Do-It-Yourself Bat Detector Kit

About this product

Build your own ultrasonic bat detector and listen to the sounds of bats as they fly overhead.

This bat detector kit is simple to assemble and does not require any soldering skills. The printed circuit board is fitted with all of the required components. All you need to do to complete the kit is to plug in the remaining parts then connect the circuit board to the microphone, loudspeaker and the control elements. A 34-page manual (in English and German) provides detailed assembly instructions.

Once assembled you can take your detector out into the field where the sounds made by nearby bats will be transformed into a frequency which is audible to human ears. Tune the detector to the correct frequency using the left-hand dial and adjust the volume with the right-hand dial.

The completed bat detector is powered by a 9V battery (not included) which will provide up to 25 hours listening time.

Not suitable for children under 14.
