DTI-300A Diver Acoustic Receiver

The DTI-300A is a small battery-operated acoustic receiver that tracks and locates underwater acoustic beacons and a unique family of acoustic transponders. It is ergonomically designed and displays navigation data via an LCD display. Sealed switches allow the diver to access the control and utility functions of the receiver.

When operating in passive mode, the DTI-300A can locate standard acoustic beacons that operate from 25-40kHz. DTI-300A display guides the operator with signal strength and bearing to the selected acoustic beacon. A built-in electronics compass gives additional directional support in keeping the diver on course.

The DTI-300A can also track and locate transponders designed to work with the receiver. These transponders, ATT-400, allow divers to mark targets underwater and relocate them up to 1000 metres away. Once an ATT-400 has been interrogated, the DTI-350FN gives accurate range and bearing to the transponder - to within 1 metre. Because the ATT-400 can be programmed to operate on eight different channels, the DTI-300A can relocate eight different locations simultaneously.
