Product Description

Lets you hear the amazing world of high-frequency sounds. Many uses in the scientific field especially entomology to study insects, bats and other animals. Also used for man-made sounds such as leaking air, water, gas, steam, pipes, etc. Or as a detection device allowing one to hear animals or people walking in the woods on dry ground, even through wet grass. A crumpling plastic bag, the jingling of a key chain, etc. This unit opens a whole new world allowing you to listen to sounds you didn't think even existed!

Hear The Astounding and Incredible World Of High Frequency Sounds - Beyond That Detectable By The Human Ear!

Hears Ultrasounds and Rejects Normal Sounds

Battery operated directional device detects sounds beyond the range of human hearing, with narrow band tuning from about 23 to 27 kHz (-3db points), allowing you to hear and pinpoint mechanical, electrical and biological sounds such as leaking gases, air, water; corona leakage; motor frictional sounds potentially including bearing wear breakdown noises; bats, insects, and other sounds of mother nature; a hunter's aid for high frequency sounds made by animals traveling through dry woods or even wet grass -- even beading water! There are countless applications for this unit.

Pinpoint Those Annoying Sounds Coming From Animal Repellers, and Those Who Might be Purposely Using Ultrasounds Against You for Harassment

The 12" aluminum parabolic dish increases the amount and sensitivity of collected sound (increases the reception of fainter sounds, or those from a longer distance), and provides more of a directional target location.
