Relocation of a Marked Site
Low Visibility Equipment RelocationSonotronics, Inc. offers an Under Water Diver Receiver that allows a diver to approach an object or animal marked with an ultrasonic pinger*. The UDR can achieve ranges exceeding 1km, while still allowing relocation in zero visibility. The UDR comes with waterproof headphones and has variable gain control to maintain good signal strength and directionality during approach of the target, as well as volume control and a backlit display. The UDR is user programmable for frequency and gain ranges.
