Can't hear the calls of bats? With the right technical aids, you can! This bat detector kit makes it an easy and fail-safe exercise: the circuit board is already equipped with numerous SMD components. You only need to solder in a few parts yourself and wire the circuit board to the microphone, loudspeaker and control knobs. Modern integrated circuits ensure high sensitivity and volume. However, it is not only bats that emit ultrasound, but also numerous technical devices.
