UltraSoundGate Player BL Light

part #70113

UltraSoundGate Player BL Light is a cost-effective ultrasound playback unit for luring bats. The system consists of an USB computer interface, D/A converter, power amplifier, speaker, tripod mount and playback software. It is entirely powered from the USB interface of the computer (bus-powered), which means that no additional batteries are required. An attachable eye allows to hang the unit on a mist net pole or a tree.

The comfortable playlist feature of the accompanying RECORDER USGH software allows to play both original, noise-reduced or fully synthesized bat calls in random order and at random intervals. A growing collection of European bat sounds that are suited for this purpose is available at www.batcalls.com.
