One evening, a bat found its way into our bedroom and flew backwards and forwards in a figure of eight and we were able to watch it for a considerable time, even taking some video of it in flight. Eventually, after we'd opened all the windows wide, it flew out. This increased our interest in the bats so we looked for a bat detector to enable us to 'listen' to the bats' ultrasonic echo-location noises, and perhaps identify them.

Now we are offering three bat detectors from Stag Electronics that will cover most requirements and enable you to discover more about these fascinating creatures that share the night with us.

The Batbox III is the most popular detector for the majority of amateur 'bat detectives', whilst the MicroBat is more suitable for children and casual beginners. The Batbox Duet is a more sophistocated device with two different methods of frequency shifting. It is more suitable for the real enthusiast or field researcher.

Whether you buy a bat detector or not, we recommend you get the Bat Detective book and CD as an ideal introduction to British Bats and how to identify them.

This pager-sized, 103 x 61.5 x 23.5 (mm) bat detector is the simplest bat detector yet. It features a built in speaker, headphone socket, and a belt clip. The advanced circuit means that there are no protruding knobs. Membrane switches provide two selectable centre-frequencies and power on/off. The unit can be operated single-handed and because of its robustness and ease of use, it can be used by children.

Eavesdrop on the secret world of bats with this tiny but very capable detector.
