Discovery Channel Ultrasonic Detector - Argos

Discovery Channel Ultrasonic Detector - Argos

Found 11th Apr 2014
Was looking for a bat detector - this detects bats and is only £7.49

Also can listen to rodents and loads of other ultrasonic stuff that's going on around you!

Audio spectrum - from 20,000Hz to 100,000Hz.

This amazing hand held unit allows you to hear sounds normally inaudible to human ears! Simply turn on and tune in to hear ultrasounds made by bats in the night, a bee taking pollen from a flower, the reverberations of a pin dropping and popping bubble wrap! and much more. The manual lists many interesting options, plus operating instructions and the science behind the sound detection. Recommended minimum age 8 years. Requires 1 x 9v battery (not included).
