Echo Meter Touch – Upgrading for iOS

Wildlife Acoustics recently announced that the Echo Meter Touch (Standard and Professional versions), can now be upgraded so that they can be used with Apple iOS devices. There are a few important steps to take when upgrading. 

Which Apple Devices can be used? 

Wildlife Acoustics have stated that only new Apple devices that have a native USB-C connector on them will work. This means that any lightning connector-based devices will not work with the upgraded EMT even if you have a lightning to USB-C cable. If you have an iPhone 15 (all versions) or later you can use the upgraded Echo Meter Touch. 

How to upgrade your Echo Meter Touch

Firstly, make sure you have the EMT with the USB-C connector. Micro-USB will not work with this upgrade specifically for Apple devices. Here are the steps you have to take: 

1. Check to make sure you have the latest Wildlife Acoustics app installed on your Android Device. When you update the app it should display an announcement telling you that Apple is supported.

2. Plug your EMT into the Android device.

3. Using the menu found in the top left corner of the screen (displayed as three horizontal bars). Select Settings.

4. Scroll all the way to the bottom of the Settings menu, and select Advanced Settings. 

At this stage the app will tell you what version of firmware you have on your EMT. If it is version 2 or later, then you do not need to update to get iOS compatibility. However if there is a new firmware update, even if your device has version 2.0 or later, you should update the EMT to get the best possible experience from the EMT. 

5. If the EMT is shown as having version 1.3 the app will offer you a later version of firmware.

6. Select Update Module Firmware – DO NOT UNPLUG YOUR EMT Device

7. Let the app perform the upgrade and is will display the notice saying a firmware upgrade has been successful. 

8. Once, this appears, remove your EMT from the Android device, and re-insert it to double check the device is updated. 

Now that you have accomplished the firmware update you should insert the EMT into your Apple device. If you have downloaded the Wildlife Acoustics app to the Apple device it should function correctly. 

 

NHBS manufacturing – a year in review

2023 proved to be a pivotal year for the NHBS manufacturing team, one in which we enjoyed new and continued partnerships with key organisations, overhauled the NHBS Harp Trap with the aid of leading UK ecologists, and continued to refine our existing products. 

A glimpse into the manufacturing workshop at the NHBS offices in Totnes, Devon.

Fine tuning the NHBS Moth Trap 

Since its introduction in late 2019, the NHBS Moth Trap has been a consistent favourite with hobbyists and professionals alike. However, a manufacturing team consistently motivated to improve our products and with an ear to the ground for customer feedback resulted in an evolution of the trap in 2023. The new design is more robust, lighter and more cost-effective.  

By changing the design of the lamp support, our manufacturing team were able to reduce the amount of steel used, saving on both weight and cost. We also upgraded the material used for the moth trap panels to a more rigid and environmentally friendly material, constructed from 70% recycled plastic. Finally, our team developed a system that allows the NHBS Moth Trap to run off a 12V battery using an inverter kit. A full night’s trapping is now possible using a single battery. 

The NHBS Moth Trap was designed in consultation with Butterfly Conservation. NHBS is proud to support the excellent work they carry out with each sale of the trap.

Nets for every occasion 

There is a sense of pride in the development of the iconic orange banded nets that NHBS produce. Without knowing it, you may have seen them in action on prime-time television shows including Springwatch and the BBC flagship series Earth that featured Chris Packham using an NHBS plankton net in the first episode.  

Our bestselling Professional Hand Net also forms a key part of the Riverfly Partnership approved survey kit. Our relationship with the Riverfly Partnership dates back to when NHBS originally acquired EFE & GB Nets in 2016, and we are pleased to further support the Partnership by making a donation to them with each sale of the kit. You can find out more about the great work the Riverfly Partnership are doing in our previous blog and on their website. 

Conservation research and monitoring 

At NHBS we are experienced in working with our customers to either develop or improve equipment for use in monitoring wildlife. Where necessary we seek out experts who can examine the design of the product and give feedback on improvements; not only to meet project requirements, but also to ensure the design is sympathetic to the wildlife that are subject to the equipment’s use.  

Early in 2023, we wanted to overhaul our Three Bank Harp Trap and so reached out to respected and experienced ecologist Neil Middleton of Batability. Neil and his team gave crucial feedback on the trap’s existing design and highlighted areas where improvements could be made. This allowed our manufacturing team to refine the design so that it maximised the safety of the bats that were caught, as well as making it easier for ecologists to use. By listening to the experts and users and making their recommended changes to the design, we now have a product that we are exceptionally proud of. 

A visiting team from LIST collaborate with NHBS engineers on the exciting NEWTCAM project.

NHBS manufacturing in 2024 

This year promises to be full of exciting developments, including the NEWTCAM project that NHBS is working on in collaboration with the Luxembourg Institute of Science and Technology (LIST).  As well as providing a novel approach to monitoring amphibians, NEWTCAM represents a very different type of technology for our manufacturing team, giving them a chance to learn valuable skills which can be utilised in future products. The first units are currently in production and will be made available to early users for field testing from spring 2024. 

At NHBS we are committed to finding the best materials and are constantly working to improve the sustainability of the production methods we use. If you have a project or product you think we could help with, please do not hesitate to get in touch using our contact form. 

Made in Britain Logo

We are also pleased to announce that we have been awarded the use of the Made in Britain logo for all product manufactured in our NHBS workshop in Devon.

The Seal Project: Q&A with founder Sarah Greenslade

The Seal Project text written in a circle with a multicoloured seal pup in the middle.The Seal Project is an environmental conservation charity based in Brixham, Devon, which monitors, surveys and manages the welfare of seals on and around the South West coast, particularly Torbay and South Hams. Alongside seal conservation, the charity also focuses on engaging, involving and educating the community on the importance of protecting our ocean wildlife through presentations, talks, assemblies in educational settings, workshops and public events. Sarah Greenslade spent many years working as a key member of the British Divers Marine Life Rescue before establishing The Seal Project in January 2019. 

Sarah, founder of The Seal Project, took time out of her busy schedule to answer our questions on the amazing work of The Seal Project, the effects of climate change on the local seal population, the importance of raising awareness, and how the current pupping season is going. 


What is the Seal Project and where are you based?

The Seal Project is a small conservation charity based in Brixham that monitors the Grey seals in South Devon – mostly around Brixham, but we now also monitor the coast between Dawlish and Prawle Point, including the River Dart. The charity was born out of a need to protect the seals seen locally, many of which are animals we know individually from all around our stretch of coastline. 

How did you get into seal conservation?

The story began when I encountered a Common Seal Pup stuck in Brixham’s Shoalstone seawater pool – who do you call at 5.30 in the morning? Myself and my best friend had no idea. The RSPCA don’t wake up that early and we had no clue what to do, but we knew that leaving the pup where it was wasn’t an option as people were walking dogs and the seal was clearly in the wrong place. My partner Lee (now a trustee of The Seal Project) suggested wrapping it up in something and putting it back in the sea. We had no hoodies or coats, so my friends partner was called and he brought down their most luxurious fleecey blanket off their sofa (as you do!) The seal, who had been swimming in the pool, came out and literally stopped at my feet. I scooped up the pup in the blanket as if it was a sleeping child and it never struggled once. We never touched it as we carried it over the rocks to the sea and let it free. As soon as we released it, another seal appeared – knowing what I know now that was most likely its mum – and off they went. The pup had clearly come in on a high tide and got stranded and the mum couldn’t get through the railings. If that was a grey seal it would have been abandoned there and then but Common seals are more devoted mums, and I hope to see this seal as an adult at some point.

After this, I became a Marine Mammal Medic for the British Divers Marine Life Rescue (BDMLR), which sends medics to call outs for marine life in distress, mostly seals, dolphins and whales. My first call out was to a ‘speared’ seal which quite literally resembled a tv ariel in the sea. She was eventually sighted locally without the spear attached, however it seems that every seal has some kind of back wound. She, like all seals, has unique identifying marks including their individual fingerprints and fur patterns, in this case a specific ‘W’ shape to the right-hand side of her head. I knew I had a photo showing that she was alive and well, and that resighting along with later  identification of an animal known by the Seal Research Trust (Cornwall Seal Group Research Trust), with whom we share all our data, are what first sparked my interest in using photos to identify individual seals. After providing the identification I spent two weeks getting called out to every seal sighting in search of the previously speared individual, and it’s all gone a bit mad since then!

We are at the end of October, which is around the time Seals finish pupping. What has it been like in the Torbay area for pups this year? 

I’ll be honest, it has not at all been as expected. Three of our known mums have not been seen for ages, and a first-time mum has been identified as a seal we know which we didn’t expect to be pupping just yet. The strange summer/autumn weather also means people are now using the coastline with their watercraft year-round and paddleboards and kayaks are now easily affordable too, so people are everywhere. Pupping seals who once had the coastline to themselves once September kicked in are now finding they don’t have these spaces to themselves, and as such pups are born or washed up in busy locations. This often results in a call out to BDMLR (as has just happened on the day I’m writing this).

Being based in a tourist area, what challenges do the seals and The Seal Project face? 

That’s a good question. Hand feeding is probably our biggest problem. When we first started, our mentor and amazing friend Sue Sayer MBE thought that us starting a Brixham-based project would have a negative response as this is a major fishing port and some believe that seals ‘eat all the fish.’ But bar the odd comment, and a tiny number of incidents involving fishing and tripper boats hand feeding seals, we have experienced very few problems with the commercial operators in Brixham.

As a tourist area another big problem is angling-line entanglements. Our Breakwater is a busy area for novice anglers and they tend to feed the seals in an attempt to make them go away – clearly that doesn’t work. Also, some seals are sadly too habituated and get caught in angling line regularly. With adult seals there is nothing that we can do about this, and they have to be left to themselves until the hooks rust or fall out. Stones are also often thrown at seals to make them go away, and the animals are uncommon at a couple of locations where more ‘commercial’ land angling takes place.

Our biggest challenge is lack of awareness. We spend so much of our time trying to raise awareness and get the message out there which requires help from the local authorities and the tourist boats, but this doesn’t seem to be happening and it’s frustrating for us. We should all be working together, and the amazing local wildlife – including seals – should be respected and appreciated. Without our incredible wildlife many tourist boats would just be ferry services.

What projects or research have you been carrying out or got planned for the future?

We monitor and record all seals, sightings, dates and locations to try to build up a big picture of the seal population around our coastline. We now know many seals well and have been gathering data since 2016/2017. Matching our seals to individuals from Cornwall is difficult as there are very few other locations on the south cost carrying out monitoring in this way. Therefore, unless an image of a seal happens to be shared on social media or passed onto us from a private group, our records are mostly limited to the confines of our study area.

We do however have sightings of seals which have been released in Cornwall or seen in north Cornwall. We would love to be able to find out where else our seals have been seen and to build a better picture of their travels. Given that we do have Cornish seals visiting our area, we’d like to know if they behave differently to the individuals normally resident in Devon; my Cornish surveys show that the seals there are much more skittish than the individuals we see in Brixham, which tend to be relaxed and show little concern around the noise and traffic of this major fishing port. We do also have a couple of students planning research, but as of yet nothing is confirmed. Our data is not in the best shape and every sighting of each seal takes time to document – identifying one seal can take seconds or hours, and as this is all done by eye the catalogue is a minefield to get involved in! 

How has climate change impacted the local seal community? 

At this time, I can’t say for sure. My biggest concern is the fact that seal pups, born with white fluffy coats to be camouflaged in snow, are increasingly being born in hot September sunshine, and therefore once abandoned they are at a greater risk of dehydration due to being on sunny warm beaches when it should be much cooler. This year, numbers of seals appear to have been increasing unusually slowly as we head towards the winter months, but we’re yet to reach peak winter season to be able to confirm whether numbers will remain low. Our only other concern at this time is for the three mums who we’ve not yet seen pup this year, as they’ve been so predictable for the past few years.  

Do you have a success story you’d like to share with us?

We first encountered him in 2020 as a juvenile seal entangled in industrial strength plastic. He vanished and we feared the worst, however a week later, on Easter Sunday, he was back in the same haul out spot on a girder in the marina, freed from the plastic. At the time of our first sighting, he appeared to have a bunny shape on his right-hand side (alongside a letter ‘A’), but this time the bunny seems to have disappeared with the ‘A’ is clearly visible. He reappeared regularly over the coming years, often seen for a few days and until the last several months always in the same spot, before disappearing for a few days and coming back again. We have seen him elsewhere a number of times, and last winter he was seen socialising with two ‘tagged’ seals (former rescued seals with plastic rear flipper tags for identification), so we look forward to seeing if they return to the area soon too.

Conservation volunteering with Wild Planet Trust’s Seagrass Project

I recently had the opportunity to witness first hand a team from the Wild Planet Trust working to survey seagrass meadows in the Torbay area. The ‘Save Our Seagrass’ project, which has been going for some years, involves repeated survey work throughout the year to assess the meadows’ health and the diversity of marine life that they support.  Having lost over 90% of seagrass meadows around the UK in recent centuries, these surveys provide vital information about the growth or decline of existing meadows, as well as potential impacts from factors such as global warming.

Megan and her team of volunteer divers met with me early on a Saturday morning to travel out into the bay to survey three specific meadows: Fishcombe Cove, Torre Abbey and Breakwater Beach. Each of these meadows carry unique characteristics derived from their locations. Torre Abbey is situated close to the harbour entrance of Torquay and is very shallow during low tides. The Breakwater Beach area is home to local swimmers and tourists.

The third site, Fishcombe Cove, near the fishing town of Brixham, holds a key to solving one of the problems that has contributed to the deterioration of the meadows. There are typically many reasons why a meadow sustains damage and/or gets wiped out, the most obvious being where fishing nets are trawled across the seabed. But more and more these days, casual leisure boat users cause damage by dropping their anchors. When damage occurs, it can take ten years or more to recover, assuming that the conditions are favourable.

An innovative approach to solving this problem has been using the deployment of “no anchor” buoys such as those that are situated in Fishcombe Cove. Designed to allow up to three boats to moor without dropping anchor, these buoys are chained to the seabed and have smaller submerged buoys attached to them which keep the chain from scraping the seabed and damaging the seagrass.

The surveys such as the one I observed use two different methods: a transect and a spiral form, and each dive team is equipped with a float with a GPS unit that stays on the surface and records their location as they move through and around the seagrass meadows. Each diver carries two hours’ worth of oxygen to be able to carry out the surveys at anywhere up to ten meters depth.  With underwater cameras they record the general health of the area and any unusual sightings along with expected marine life.

One of the observations from the divers from the surveys that I attended was the extent of life that had grown on the chains for the buoys, along with shoals of Bib (Trisopterus luscus) that were using the seagrass for cover. Around the meadow near Torre Abbey, plenty of additional life was found including Pipefish (Nerophis ophidion), Common Cuttlefish eggs (Sepia officinalis), Hermit Crabs (Pagurus bernhardus), gobies, periwinkles and Sea Slaters (Ligia oceanica).

All the data from the dives will be collated and, following a single additional dive day schedule in October, the team at the Wild Planet Trust will start the process of analysing the collected date from this year, looking at how the meadows have changed in comparison to previous years.

In the Field – Hawke Endurance ED Marine Binoculars 7 x 50

Introduction. 

Choosing the right binoculars for either your hobby or work is something you should spend time on. While using binoculars on dry land sometimes has challenges with poor weather conditions, if you then wish to use a pair of optics out at sea, you should consider some additional points. 

Wind, changing light conditions and weight are amongst the deciding factors on what makes a good pair of optics but add variable movement and changing landscapes to the list of elements to assess a pair of binoculars and you need to review your selection even more carefully. I’m very lucky to be able to have access to a boat for cetacean spotting and surveying. With that in mind, I decided to put the Hawke Maritime 7 x 50 binoculars through a test. But one thing that always makes it a challenge is the sea state, coupled with fast-changing light and weather conditions. Many of the points outlined below still form part of the normal considerations for use on land, but I’ve tried to extend the thoughts to the case of ‘at sea’. 

What to look for in a pair of marine binoculars? 

Crisp image 

I have found that some binoculars are let down, not by the amount of light going through the lens elements, but by the overall quality of the image. While a bright image is important, chromatic aberrations can cause issues with the identification of surface or flying objects, especially when they are near the edge of the field of view. When the sea state is above 1 (calm or glass-like), there is more movement in the wave height and the amount of time you have to determine the object on the far side of the wave is reduced. Is it a bird, or a dorsal fin? At certain times of the year, it becomes even more of a challenge when you have adult guillemots on the surface of the water with their black and white bodies that can look like the dorsal fins of cetaceans.  

This is also important with the large field of view. Maritime binoculars are all about the amount of vision you have. If you are a skipper on a boat and need to make decisions that affect the safety of your vessel, then seeing more of what is at a distance from you is critical. The choice of a BaK-4 Roof prism also plays into the quality of the image as this design of prism is reserved for higher-end products, and it shows with the quality of the image. 

Brightness 

The overall brightness of the image in all weather conditions is a big help. Timed survey periods for cetaceans rely on the confidence of the surveyor in deciding what they have seen. Whether the light is behind you or in front, the subject brightness needs to be enough to see markings, details of any dorsal fin damage (nicks, cuts), and for the assessment of age. Typically, the youngest calf will have fetal folds on its body, and a bright image will assist in making out those factors to allow assessment of age as they lose these folds after about six months. The Hawke Endurance ED Marine binoculars come in two sizes of front element, the larger giving a brighter image, but at the cost of weight (see below) with the larger binoculars being over 50 per cent heavier than the smaller version. I tested the 7 x 50 version which did not disappoint in brightness and, in my opinion, worth the cost in weight. 

Wide field of view 

The difference between the two main pairs of binoculars in the range from Hawke is dictated by size. The smaller version (not tested) is lighter in weight and contains a smaller front element (less brightness compared with their larger version) but with a greater field of view. This may be part of your decision for the selection as it is worth remembering that the amount of extra view may not be as much as you first thought. A useful tip to remember is that one degree of field of view equates to about 17.5 meters at a distance of 1000 meters. So the difference between the two versions of the maritime product is just under 23 meters of view!  

Waterproof 

The binoculars have been rated IP67. Technically they are waterproof and can be immersed in water for a short period of time without any problems. Hawke have given consideration to this by adding a set of float-assisted neck straps. Coloured bright yellow, it makes it easy to spot should you accidentally drop them over the side of the boat. The strap will keep them afloat. Needless to say, I didn’t test this benefit! It is also worth keeping a cloth with you for wiping away the salt water as, no matter how durable a pair of binoculars can be, sea spray will eventually damage the product. 

Weight 

The 7 x 50 binoculars compared with many others are no heavier than the average. However, my view on weight is reflected by the circumstances of use. If you intend to use them on a boat, and the conditions are less than calm, then holding them with one hand while using your other hand for stability is a great test. Long periods of time holding them in one hand can start to strain the wrist. Using the neck strap is important. 

Conclusion

I found the 7 x 50 binoculars to be a joy to use. Overall, the specifications have been well thought through, and provide the majority of what you would need to survey. They even produce a version with a compass built in, which I can imagine would be a further benefit for recording the sighting direction when surveying. They are comfortable to hold and generate a bright image, making it easy to identify the subject matter. It should also be noted that Hawke provide a lifetime warranty on product defects, which I feel is an outstanding part of the manufacturer’s services.

In the Field – Kite APC Stabilised Binoculars

Kite Optics has always been a provider of high-quality optics, and we were thrilled to be given the opportunity to test a pair of stabilised binoculars from their range. The Kite APC Binoculars are purported to be ideal for watching birds and other wildlife. The big draw is the construction and ability to stabilise the image for more accurate observation.

Unpacking

Opening the box, you find a neck strap, carry case, instruction manual and the binoculars themselves. The first impression of the binoculars is that they look and feel ready for anything. The binoculars’ rubber casing provides an incredibly easy grip while giving you the feeling that they could withstand a little rugged handling.

To start with

Before using the binoculars for the first time you need to take the necessary first steps, as you would with any pair of binoculars. Adjust the dioptre ring to take care of any sight needs, alter the width of the eyepieces if needed (which was simple as they are linked together mechanically to create a single round image when looking through the eyepieces) and insert some batteries.

This is essential to get the full impact of what these binoculars have been designed to give you. It should be noted that the manufacturer clearly states that you should not use rechargeable batteries in this product. As with all electronics that may be put away for periods of time, you should also not leave the batteries in the binoculars while stored. Though you only need to use two batteries to run the stabilisation, there is a compartment for another two batteries, effectively giving you double the length of use while out in the field by swapping over tired batteries with the spares.

To access the battery compartments, you need to look at the front end of the binoculars. On either side of the lens, you will see recessed openings with plastic lids that have flip-out handles. It was a little fiddly at first to get hold of these, but once raised, opening the compartments was easy. When replacing the lids on the compartments you cannot over-tighten them. When screwing them shut, you will reach a positive stop.

How we tested them

Originally the plan was to take the binoculars out on a boat to view birds, seals and dolphins. However, in the timeframe, it wasn’t possible as the weather stopped the trips going out. An alternative was to take the binoculars up to a local reserve in Devon, Berry Head. An ideal location for watching the sea traffic, scanning the water for cetaceans and viewing the local guillemot colony that is nesting on the cliffs, along with other pelagic species.

The objective here was to see how well they handled the windy conditions and the distance to the subject both on the water, in the air and on the cliffs.

What we found.

With a relatively clear and bright day to start with and a medium wind, it was easy to break the test down into three areas based on subjects. Walking to the edge of the headland, I started scanning the sea. Plenty of gannets were around in a couple of sea locations and, while watching them, they started to dive. Initially, I left the stabilisation off just to get a good understanding of how they felt based on having to compensate for any shake with my hands. It quickly became clear that was quite tiring on the wrists and fingers while keeping the image as steady as possible. These binoculars can be quite heavy, though you should take into account that they contain stabilisation technology. Turning on the stabilisation, using the horizontal dial, and raising them to view, I was amazed at the change in the viewing experience. If you have ever used a more recent phone to shoot video, you will understand the concept of the gimbal mechanism that is deployed in the binoculars. The image became a lot smoother, even with irregular gusts of wind. Being able to track the birds not only in flight but as they dived made the experience much more informative. While watching the gannets, the extra magnification enabled me to view them angling their heads to the side to look down on the sea while searching for fish.

A fortunate moment occurred while the birds were diving. Something I had hoped to test on a boat occurred with the appearance of a cetacean. There are five different cetacean species off our coast in Brixham. The one that is most difficult to spot because of their surfacing behaviour is the harbour porpoise. Typically, you get a fleeting glance as they surface and then they are gone, reappearing after some minutes in a different location. Harbour porpoises are more solitary in their behaviour which can also add to the challenge. But with the sharpness, contrast and stability of the binoculars I could scan around the area the birds were feeding and note any surface disturbance, sometimes pre-empting the moment the porpoise surfaced. This coupled with the clarity of the optics gave me the chance to identify the species, recognising the small angular dorsal fin before it submerged again. It should be noted that there was a slight chromatic aberration around the edges of the image, but this was outweighed by the image quality where it counts.

The final test was to visit the opposite side of the reserve and use the vantage point across the cove from the nesting colony. This is some distance away on the cliffs, so again I decided to turn off the stabilisation and try to look at the guillemots before switching it on. To provide a comparison I shot a couple of videos through the eyepiece to show the stability of the binoculars before and after activating the stabilisation. It’s apparent that, if you were trying to assess colony size, you could quite easily carry out a census using these binoculars.

Opinion

These binoculars are built to withstand a good level of environmental bashing! With a waterproof construction (IPX7) and the rugged covering, I wasn’t afraid to use them out in the elements. The clarity of the view through the binoculars provided a level of confidence in judging the scene and the species within. Contrast and colour were well represented, which is incredibly important when bird watching as this will be the difference between identifying one species over another. The stabilisation was a real game changer, especially for identification purposes. I would feel good about using these on a boat to be able to survey cetaceans as when you halt the boat, the rocking on the sea would make this an ideal advantage for scanning the water. Good thought has been put into the design of the controls, with a large horizontal focusing wheel easily accessible and controlled using the tips of fingers. The stabilisation switch has been designed not to intrude on the use of the binoculars. Turning the stabilisation on lets you forget about the need to activate them. When you aren’t using the binoculars and they are in a vertical position, around your neck, for example, the stabilisation goes into sleep mode, improving the battery life. I would mention that they are quite heavy, without the stabilisation you could get fatigued trying to compensate to keep the image static, but with the stabilisation active, I know the stress on the hands would be less.

Equipment in Focus: Spring Frame Butterfly Net

The Spring Frame Butterfly Net is a compact net for anyone interested in studying butterflies or moths. Designed and built by NHBS in our Devon workshop, the net comprises of a short-handled frame, net and cover.

Bag, Net, Spring Frame and Instructions

Because of its lightweight metal frame, it can be folded down to fit into the supplied travel bag, neatly allowing it to be stowed away in a rucksack while out in the field. The main net is olive green and opens to a diameter of 30 cm. The short handle makes it easy to use at close quarters while trying to sample butterflies. 

When you receive your net, you will find it collapsed down inside its carry bag along with instructions for folding it back into the bag after use. To help you do this, I’ve gone through the process of collapsing the net in the steps below.

Steps to collapse your net

Start with a hand holding the open net with the bag draped below – held in the right hand.

Grip the top of the frame with your thumb ready to push from the underside of the frame.

Keep your right thumb over the screw that attached the frame to the handle.

Use your left hand to twist the frame into a figure eight. Your left thumb should help because it will be pushing from underneath the frame.

Twist almost completely with your left hand over the top of your right hand with your index finger ready to clasp the folded rim. The frame should naturally want to fold over itself.

With the frame folded, use your left hand to wrap the net around the folded frame to keep it from springing open. The net can now be safely stored in the bag provided.

Other equipment

It is also worth considering stocking up on a few supplies if this is the first butterfly net you have bought. 

A spare net: While the net is hardwearing, it is always worth considering keeping a spare net on hand. You can purchase additional nets on the NHBS website. 

 

 

A hand lens: Ideal for examining any butterflies that you have sampled. NHBS carries a selection of hand magnifiers that you can keep in your pocket. This particular lens is a 15 x magnification which is extremely good for viewing the beauty and detail of the butterfly.

Collecting pots: NHBS carries a selection of different types of pots that can be used for transferring a butterfly from the net to something you can view the butterfly with.

In the event that you wish to extend the handle, additional lengths and styles are available. For example, you can extend the handle to either 50 cm or 90 cm with the fixed length long handles such as the Professional Butterfly Net: Handle, or for a more flexible approach you can choose the Telescopic Handle that extends the range of the net between 82 cm and 125 cm reach.
