When programmed as a transponder, the ATT-400 works with the DTI-300, STI-350 or VADR-6000M to mark and relocate targets underwater, in ranges up to 750 meters (2,461ft). A manual ON/OFF water switch activates the transponder where it can remain in receive mode for up to 18 months (based on model), waiting for signal from the DTI-300, STI-350 or VADR-6000M. The ATT-400ST has a built-in strobe light that blinks when interrogated, making diver recovery easier in poor visibility. It can be programmed to operate as an acoustic pinger with eight user selectable frequencies from 27kHz to 34kHz. With a 2 watt output, it provides a range of up to 1,800 meters with a standard receiver like the PRS-275. Made of a non-corrosive material, the ATT-400 can be depth deployed to 6,000 meters.
