Titley Scientific have released a new update for the Anabat Scout Bat Detector. The firmware update (Version 1.0), is an important update that should be applied to all detectors as soon as possible.
The Version 1.0 fixes the following bugs and introduces the following changes:
Fixed volume adjustment bug fixed, allowing the detector to remember user-set volumes.
Added a trigger min event to settings window.
The max memo file time is now set to 10 minutes (was 10 seconds).
Added a warning message when clock battery gets low.
Disable the audio output when recording a memo; reducing and preventing interference.
Fixed a bug that sometimes causes log files to be created in the root directory of the SD card.
Titley Scientific are continually improving the software to add features, remove bugs and address performance issues. It is vital that you install new updates as soon as they become available to ensure your detector runs smoothly.
How to perform the update:
Step One – The Anabat Scout is updated by downloading the new software onto an SD card. Simply download the update file using this link (.adx file) and copy this file, in its original format, in the root directory of the SD card. Make sure the file is named scout.adx. You can use the same SD card to update multiple Scouts.
Step Two – Insert the SD card and fresh batteries into your Scout then power it on. After a short period the message: “Firmware update 1.0 available. Would you like to update now?” will appear. Press the “Yes” key (top right hand soft key) to start the update. Do not remove the batteries or power off the detector while the update is being installed. Two squares will scroll across the display while the update is being installed and then the detector will restart. The update is now complete.
Note: To check that the update was successful or that the latest firmware is already installed on the Scout go to: Menu, Other, Update and check the version is 1.0

With Spring around the corner and the bat survey season fast approaching, it is a great time to make sure you have everything ready for the busy months ahead. Over the winter we have been busy reviewing our current products and cataloguing new ones. Here, we have picked out some exciting new products as well as some old favourites to take a look at.
The NHBS Harp Trap
Designed and built on-site at our workshop in Totnes, our three-bank Harp Trap features some innovative designs such as a winding line carrier and anti-tangling system that makes assembly and disassembly, easy and efficient. Made mostly from aluminium, the trap is surprisingly lightweight at just 15kg, whilst remaining sturdy and durable during use. The harp trap is 190cm long and has a catch area of about 4m². The catch bag is approximately 60cm deep and its entrance is about 39cm wide. When collapsed, the catch bag wraps around the disassembled frame and is held tightly with Velcro straps so that it can be neatly stored and carried in its bag. Initial feedback on its design and function has been very positive and we are excited to develop our design based upon suggestions from professional bat workers. Our standard trap will be a three bank, but if you would like a bespoke two or four bank trap, please contact us so that we can discuss your requirements.
BTHK Tree-Roost Net
Based on the design by Henry Andrews from the Bat Tree Habitat Key (BTHK) project, the BTHK Tree-Roost net is uniquely designed for trapping bats as they emerge from tree roost sites. The net is set up against a roost site prior to dusk so that it will catch any bats that emerge, keeping them safely in the bag ready for identification, measuring and ringing. The diamond shape of the net head can pivot and collapse inwards to ensure that the net fits flush against any tree, making it safer for bats and easier for surveyors. The net bag is made from fine woven nylon mesh that is soft and will not damage the delicate wings or feet of bats. The net bag can be easily removed for cleaning and features a clear plastic rim that fits around the collar and prevents bats from climbing up and out of the net when it is in place. The length of the handle is 4 meters (breaks down into 3 sections for ease of transport) and the depth of the bag is 1 metre. You may also be interested in the book Bat Roosts in Trees which is a guide to finding tree roosts.
Song Meter Mini Bat Detector
Wildlife Acoustics’ newest bat detector – the Song Meter Mini – is a more lightweight and affordable alternative to the SM4BAT (see below). Their smallest detector yet – weighing only 290g including batteries – the Mini allows you to set up and schedule your recordings using your mobile device and a free, simple-to-use app. The detector performs full-spectrum and zero-crossing recording and can record for up to 30 nights using four AA batteries. An optional acoustic microphone allows you to record birds and other wildlife when not recording bats. For more details, see our dedicated blog post where we test this new detector in the field.
The Anabat Scout is the latest bat detector by Titley Scientific. The Scout was designed with UK and European bat biologists in mind and is tailored for active bat surveying. It can record both full spectrum and zero crossing files and stores them on a SD card with every file geo-tagged. The Scout has heterodyne, auto-heterodyne and frequency division audio that can be played through earphones or its own built-in speaker. The in/out bat counter is ideal for emergence surveys and will automatically timestamp and geo-tag every count. The small OLED screen displays crucial information without being too bright or distracting and the Anabat Scout will be compatible with Anabat’s free Anabat Insight software for viewing and analysing your data.
Elekon Batlogger M
The Elekon Batlogger M is great for active surveying and full spectrum recording. The weatherproof FG Knowles microphone has a range of 10–150kHz and can record in 16-bit full spectrum. The Batlogger M also logs the GPS coordinates (via an integrated GPS receiver), and environmental temperature at the time of recording. Different recording settings (scheduled, permanent, or triggered), and different trigger thresholds (for call identification) can be set up and the device comes with its own powerful but user-friendly call analysis software package
Echo Meter Touch 2 Pro
The Echo Meter Touch 2 lets you record, listen to, and identify bat calls in real-time on your iOS or Android device. All you need is your Android or Apple device (see the nhbs.com website for compatible models), your Echo Meter Touch 2 Pro, and the Echo Meter Touch App which is a free download from the iTunes Store or Google Play Store. When plugged in, the Echo Meter Touch 2 enables you to listen to bats in real time, view live sonograms in full colour, record onto your device and identify calls to species level in seconds. If your device has GPS functionality, the Echo Meter Touch will also log the recording location and path of the recording session. There are two versions available in both an iOS version and Android version. Both versions allow you to listen to calls in real time expansion and heterodyne and you can playback in real time expansion, heterodyne or time expansion modes. The trigger sensitivity and sample rate are adjustable and three gain settings allowing users to optimise their detector to their target bat species and ambient conditions.
The SM4BAT FS is a full spectrum detector for passive surveying use. Robust and weatherproof, it will record 16-bit full spectrum calls and can store up to 512GB of data. A versatile scheduling function allows you to set when you want to record and the battery can last up to 450 hours. The SM4BAT FS is easy to fit to a tree or post and is compatible with a variety of accessories such as GPS unit and microphone extension cables. The SMM-U2 ultrasonic microphone is available with the SM4BAT FS and is a highly sensitive microphone that produces high quality, low noise bat recordings over long distances. Easy to set up and producing detailed call recordings for analysis, the SM4BAT FS is ideal for unattended use in the field.
The Anabat Swift from Titley Scientific is based on the excellent design of the Anabat Express, but has the advantage of recording in full-spectrum, as well as zero crossing. Users can choose between sample rates of 320 or 500kHz and data is saved onto an SD card. Two SD card slots are available, allowing you to save more bat calls without changing cards. The Swift also has a built-in GPS receiver that automatically sets the clock, calculates sunset and sunrise times and records the location of the device. It will also record automatically from sunrise to sunset every night (based on GPS coordinates) as one of the automatic recording settings.
The BatLure can be used as a lure to improve catch rates of bats for survey or research, to attract bats to new artificial roosts such as bat boxes or constructed hibernacula, with bat detectors at training events or prior to bat walks and for calibration of bat detectors. The Batlure can playback sounds with frequencies of up to 100kHz and is capable of playing both real time and time expanded recordings of bat vocalisations. It is very compact and robust and has a tripod attachment mount, making it easy to set-up in your desired location. It plays sounds from an SD card which is supplied complete with several pre-loaded recordings. Users can also add their own recordings onto the card.
Ecotone Ultra Thin Series M mist net for bats
The Ecotone Ultra Thin Series M is ideal for catching bats and is available in 2 mesh sizes. Both are made from nylon (0.8mm monofilament) and have 4 shelves. Available in lengths from 3m to 21m, you can pick the mesh size and length that best suits your survey and situation.
Explorer Premium Digital Endoscope Camera
The Explorer Premium Digital Endoscope is lightweight and easy to operate. It can record still images or video on to a microSD / microSDHC card (not included). The screen can be detached whilst the camera is in operation and viewed up to 10m away. The camera head has a diameter of 9mm and the cable is 91cm long, giving easy access to nest boxes, burrows, nests, crevices etc. Lighting levels can be adjusted to minimise disturbance to animals.
Below are some accessories that may come in use when surveying bats:

NHBS’ staff members are wild about wildlife! To showcase this, we are encouraging our team to write blogs about their experiences with nature.
During the Summer months, Jon Flynn, a member of NHBS’ Wildlife Equipment Team attended a number of Waterway Surveys for Daubenton’s bats (Myotisdaubentonii). Read more about his survey experiences below:
“On Monday 6th July I took part in a Waterway Survey for Daubenton’s bat along a stretch of the River Teign in Devon. The survey is completed twice per year in conjunction with the Bat Conservation Trust and is part of an ongoing data collection programme for bat species around the UK. The lead for this particular survey was John Mitchell who has been surveying this particular length of the Teign, near Teigngrace, for a good number of years. It was my third survey there.
The survey was due to start 40 minutes after sunset, so we met at 9.00pm and made our way along the edge of a maize field to arrive at our first stopping point. This was to be a transect survey which meant walking a length of the river bank and stopping at ten predetermined points to record bat activity at each one. We stood at the river’s edge and immediately noticed that the river level was a lot lower than it was during our last visit a year or so ago. We recorded air temperature and cloud cover and, as we prepared, various species of bats could already be seen zooming around the trees and openings as they commenced another night of nocturnal foraging. The air was very warm, still and humid, and flying insects were everywhere including a host of moths and some less welcome biting species.
As the light faded it was time to start. With bat detectors switched on and earphones in place, we directed a torch beam on the river’s surface and awaited the arrival of the first Daubenton’s.
The Daubenton’s bat is a species which typically occupies riparian woodland. They often roost in trees along the river bank and hunt by skimming low over the surface of the water for insects. They can take prey from the water’s surface using their feet or tail membrane.
As bats skimmed through the torch beam we were able to count them. We counted the number of passes that we observed and for this a clicker counter is always useful! The bats that we heard but did not see were also recorded as additional information. I set my Magenta 5 at 50hz and listened whilst John relied on his trusty and more accomplished Bat Box Duet.
After four minutes on the stopwatch we finished counting, compared counts and wrote down results. At stop number 1 there were certainly bats present, but they were swooping around quite high above the water surface and not showing the typical behaviour of Daubenton’s – John was dubious that they were our target species so we recorded them only as potential sightings.
Using GPS devices and torches we left for Survey Point 2 further down the river bank and repeated the same process as before. At this location there was no denying that these WERE Daubenton’s bats, as the torch beam caught their pale almost white ventral fur, confirming their identity. Our detectors were full of noise too, including the typical intense zap as a bat homed in on prey.
On we progressed with eight more stopping points to go. Occasionally our river bank scrambles took us through thickets of invasive Himalayan balsam (Impatiensglandulifera) and Japanese knotweed (Fallopiajaponica)– a sobering reminder of how our countryside is changing. The night remained still and warm and it almost felt like we were in a different country.
After eight more stops my watch said 11:20pm. It was good to see that bats were in profusion that night, as John stated ‘It was one of the best ever totals, with one stopping point recording over 50 passes!‘.
Two weeks later and we repeated the process. But this second night felt noticeably cooler and there were fewer insects on the wing. Nevertheless bats were still out and about in reasonable numbers and an average score was calculated between the two Waterway surveys. Overall there were encouraging signs that the Daubenton’s bat continues to do well along this particular stretch of the Teign.”

If you like the idea of taking part in Waterway Surveys (or other kinds of bat surveys) then contact the Bat Conservation Trust or have a look at their website here. It’s great fun and you can put your bat detector to important use!
UPDATE 7th MARCH 2016 – The Bat Survey Training Course has now been cancelled.
The use of passive monitoring to assess bat activity has important implications for how we work with the vast amounts of accumulated data, and automation now plays a crucial role in dealing with datasets which often contain thousands of recordings.
This bat survey training course has been designed to give you insights into the how-to of passive acoustic bat detection and call analysis, including its pitfalls. It will give you the skills to conduct passive acoustic bat surveys with confidence and to analyse your results in the most efficient and accurate way.
Topics covered will include: Why and where do we listen for bats, how to detect bats, signal analysis, bat call identification and working with large datasets. It will also include a short introduction to the Batcorder system.
