Battery operated directional device detects sounds beyond the range of human hearing, with narrow band tuning from about 23 to 27 kHz, allowing you to hear and pinpoint mechanical, electrical and biological high-frequency 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. > Click for more information <
