This ultrasonic microphone and cable is for use with the Elekon Batlogger. It will allow you to position your microphone much more easily whilst leaving the Batlogger in a place that is convenient to change SD cards, batteries and settings. It is particularly useful when recording in caves and at the top of masts.
The cable is 100m in length and is weatherproof. The cable is supplied on a reel which makes it very easy and convenient to transport and deploy. It comes with a FG microphone which plugs into the cable and so can be removed for replacement.
