Batlogger Bat Detector

Sensitive full spectrum recording+GPS+temperature logger

Elekon Batlogger

The BATLOGGER is a compact and versatile tool with a lot of features for researchers. The 10-150 kHz ultrasonic sounds of are recorded unaltered in full spectrum on a SD card with a microphone that is one of the most sensitive BCM has tested. The richest metadata information of any FS detector is stored with each file. An important feature here is the built-in GPS receiver, and every recording is referenced by the coordinates. This is particularly valuable in elaborate setups with several recording devices, or during mobile transect recordings.

Additionally, the temperature at the time of recording is also recorded. The BATLOGGER can be used as real time bat detector as well. The integrated live monitoring (heterodyne, with automatic tuning) with speaker or headphones simplify work. A wide range of accessories make the BATLOGGER universally.

The built-in live monitoring (mixer, resp. superheterodyne) tunes to the different call frequencies automatically. On detection of bat activity, recording can be started automatically or manually and important information is displayed clearly in real time.

Scheduled recording, permanent recording, instant recording and different triggers (for call identification) can be set up. Charts and statistics summarize the recorded data clearly and concisely and can be exported for further processing.

We believe the data belongs to the user. Therefore the recordings and metadata are stored in open formats such as WAV and XML. Thus you do not need special software to use the data and can, besides our software, also use other popular audio and bioacoustics programs.

The built in, rechargeable lithium-ion battery allows recordings over several nights to monitor a site in detail and to understand the local activity. For even longer autonomous observation and protection against weather influences the BATLOGGER can be extended to a total of 153 hours (~19 nights @8h/night) with the StrongBox.

Included in delivery: Batlogger in a case, charger, headphones, 16 GB SD card. BCM exclusive: 1 extra microphone


BCM's take on the Batlogger

The Batlogger has been tested paired with the Pettersson D500x, the Wildlife Acoustics SM2BAT+, and an Anabat SD1. The Batlogger did quite well, possibly recording the most pulses of any of the detectors it was paired against. We do need to conduct further tests particularly looking for low frequency recordings below 20 kHz. No other full spectrum detector/recorder includes an integrated GPS and temperature logger, making the Batlogger an ideal "go to" device anytime you would want to do a walking or driving transect. The omni-directional microphone is not intended to be in the rain, and weatherproofing any omni-directional microphone introduces unwanted reflections and distortions, so applications for long term passive monitoring are more limited. A spare microphone is included in the package however, so troubleshooting a bad microphone is easy. Using headphones it is easy to monitor live bat activity during recording. For more information a quick start guide is available and you can also download the Batlogger manual.

Record a transect in 5 easy steps...

1. Prepare for bat walk

Press the two buttons '<<' and '>>' at the same time. The BATLOGGER starts up. Now press the '>>' button to enter record mode.

You can now begin your trip and start walking.


2. Automatically record bats!

Once a bat is within hearing distance, a recording is started automatically and their calls are stored directly and unaltered to the SD card. If the bat flies away the recording stops automatically. In addition, place, time, temperature, etc. is stored on together with every recording.


3. Finish and shut down

After the excursion, leave the recording mode by pressing the 'Menu' key ("Exit Record") and then confirm with the '>>' button. Turn off the BATLOGGER by pressing the 'Menu' button three times ("Shut Off") and then confirm with the '>>' button.


4. Load recordings into SonoBat (USA) or BatExplorer (Europe)

Insert the BATLOGGER SD card into the card reader of your PC. You can use SonoBat to view files, but the Batlogger is really intended to be used with BatExplorer to take advantage of the metadata and GPS track. Open BatExplorer, create a new project and import the recordings from the SD card to your computer. A wizard dialogue guides you in this step.The recordings are copied to the hard drive and BatExplorer starts the analysis automatically.

5. Analyze the recordings

Congratulations! You can now view, listen to and evaluate your recordings. In the project view BatExplorer shows all recorded data and the results of the automatic analysis (recordings, calls, frequencies, statistics, map, etc.). Click the "Play" button of a recording to play it, transformed into the audible range, or open the detail view of a recording by double-clicking its spectrogram.
