UltraSoundGate Player BL Pro is a full-featured ultrasound playback unit for luring bats. The system consists of an USB computer interface, D/A converter, power amplifier, speaker(s), tripod mount and playback software. The unit can be powered either entirely from the USB interface of the computer (bus-powered) or by an external 24…36 V battery in order produce maximum possible sound levels. It is available with either a single speaker (#70115) or two integrated speakers (#70116). The dual speaker version is certainly suited for luring bats into mist nets. 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.
