About this product
We currently have 2 ex-demo units available. It has been tested and is fully functional. The detector has been written on in permanent marker, and there are some signs of wear on the packaging and the device itself.
The Batlogger M from Elekon is a sophisticated bat detector / recorder designed for transect surveys and bat walks. This compact handheld device features a weatherproof FG Knowles microphone which allows it to record full spectrum ultrasonic calls over the range of 10 – 150kHz. These recordings retain details of the amplitude and harmonic structure of the original bat signal; details which play a huge role in the accurate determination of species. Files are saved in WAV format onto an internal SD card along with additional information such as location (using the built-in GPS) and temperature.
In addition to recording full spectrum calls, the Batlogger M also features a super heterodyne monitoring capability which will automatically convert bat sounds to a frequency that you can hear. Like the Batscanner, the Batlogger will automatically adjust to the peak frequency so that you don’t need to worry about missing bats or adjusting the settings yourself (although you can if you want). Calls are played through the built-in speaker or you can listen via earphones.
Different recording settings are available, including scheduled, permanent or instant as well as different trigger thresholds for call identification. All settings can be accessed directly on the Batlogger M. Alternatively, the free BATPARS Editor Software can be used to customise your settings on your PC. These are then transferred to the device via the SD card.
The Batlogger M is powered by an internal lithium-ion battery which is charged using the included charger. As this device is made by a Swiss manufacturer, please note that this charger has a type C Europlug (CEE 7/16) power plug). The internal battery allows recording over several nights, but for those who want longer autonomous observation and protection against weather influences, a Strongbox can be purchased separately which includes a set of batteries in a weatherproof case. Alternatively, if you are looking for a long-term recorder, you may wish to consider the Batlogger A+ or the Batlogger C.
The Batlogger M comes in a sturdy foam-padded carrying case, and includes a 16GB Kingston SDHC-card (loaded into the device) and a charger. For additional accessories, please scroll down to the bottom of the page.
The free BatExplorer Software for Windows allows you to manage and analyse Batlogger M recordings easily and quickly. Listen to time-expanded recordings, filter and sort to find relevant data and import, export or backup your data. A customisable spectrogram with zoom and measuring aid facilitates manual species identification. BatExplorer also includes computer-aided identification of species with the help of an integrated bat species library (European species). Requires Windows Media Player version 11 or above.
Free software is also available for Mac users (BatScope) to analyse and manage recordings. BatScope allows you to transfer recordings from your Batlogger M to a structured and easily searchable database from where you can view spectrograms and automatically analyse and classify calls to species. It also enables you to cut long recordings into single bat calls.
GPS data from the Batlogger M can also be extracted for use with Google Maps/Earth. Requires a minimum of OS X 10.6 and 1 (preferably 2) GB RAM.
The Batlogger M is covered by a 2 year warranty, please note that this does not include the microphone. Replacement microphones are available to purchase separately and are extremely easy to change - just unplug your old one and plug in the new.
The other review I found online fails to do justice to the brilliance of the Batlogger concept. Without the software you have a nice Swiss made, state of the art, full spectrum recording, heterodyne autotuning, highly sensitive bat call, time, temperature and GPS logging device (ok, that is already a quite impressive list) but combine this with the accompanying (free!) BatExplorer software and you’ll transform yourself from a bat detecting amateur into a bat detecting army, paintbrushing bat observations on hitherto unmarked territory. In Europe it is emerging as the de facto standard for bat (distribution) mapping with the added advantage that every observation is backed up by a full spectrum recording (+ time/gps/temp xml file) so as to facilitate independent verification of any (contentious/uncommon) find. The software allows you to review the recorded bat calls in time expansion and in heterodyne mode, in essence giving you the best of both worlds. The European species identification is not perfect (no such software exists at this time) but it will help you make a decision allowing you to compare your recordings with reference recordings from within the software. With some experience you will reduce the non-bat recordings due to the highly sensitive FG black microphone but a sizeable percentage still will remain. However in the BatExplorer software you will quickly learn to discern useless recordings based on their spectrograms and you will swiftly proceed to the many, many excellent bat call recordings. The whole process of reviewing your recordings using the BatExplorer is highly rewarding because thanks to the satellite view showing where your recordings took place and the instant playback of those recordings you relive your last night’s excursion as no other hardware/software platform can. Be prepared to see your (say) four hour bat detecting exploit (still getting a good night’s sleep) return HUNDREDS of valid observations assuming you have covered some distance in those four hours (needless to say this depends on the territory/time of year/weather etc.). I guarantee that for many of you the Batlogger will take your bat detecting to a new level, it is like you have a team of field biologists working for you. Now you can do for instance quick scans covering wide areas unthinkable when you just had your precious but now hopelessly outgunned non-recording/not gps-enabled/not software integrated detector of yester-year.
