The Observation & Listening Device is a parabolic sound collecting dish that can hear sounds up to 300 feet away. Just place the headphones over your head to investigate and collect evidence that a traditional digital recorder might not be able to pick up.


This device features a frequency controller, record/playback buttons, and background noise reduction to digitally record sounds that can later be used as evidence. The unit takes a DC 9-volt battery for operation on the go.
