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.
This device is not made to hear sounds that the human ear can normally perceive, but instead it will hear ultrasound beyond the range of human hearing
