SM4 BAT FS Recorder - HIRE

For Hire. Adjust Quantity for the number of weeks you want it.
If you need more than one recorder, please email us with your requirements.
 
Comes with the SMM-U2 microphone.
 
Setting the standard for ultrasonic wildlife recorders
 
Specially engineered to capture quality ultrasonic bat recordings, the Song Meter SM4BAT is the industry leading bat audio recorder.
 
With the ability to store terabytes of data and the battery life to record in the field for weeks at a time, the Song Meter SM4BAT FS gives scientists a flexible, reliable tool for conducting bat surveys.
 
New Generation Ultrasonic Microphone
 
RECORD FAINTER BATS OR BATS AT GREATER DISTANCES.
The SMM-U2 microphone is significantly quieter than the previous generation SMM-U1, and competitor's microphones. The superior signal to noise ratio results in recording fainter bats and bat calls at greater distances. In addition, more echolocation pulses are recorded, which allows more accurate identification.
The enclosure's innovative waterproof design includes a built-in mounting bracket that provides a wide range of mounting options. The microphone includes a 5 meter cable, and can connect with cables up to 100m in length with no adverse effect on recording quality.
 
Best-In-Class Recording Technology
OVER A DECADE OF CONTINUAL IMPROVEMENTS.
The SM4BAT FS intelligent recording triggers and noise file scrubber help maximize the number of bat echolocations recorded and minimize recordings that do not contain bat echolocations. The SMM-U2 along with the SM4BAT FS and its advanced trigger technology produces the cleanest and quietest bat recordings available.
 
Easy Programming
