ATT-400
RJE International's ATT-400 series of compact and easy-to-deploy acoustic transponders can operate at depths of down to 1000 meters as standard, and a 6000 meter rated variant is also available. The versatile units can be interrogated by RJE acoustic receivers to provide range and bearing information from up to 750 meters away, and can also be programmed to operate as a free-running pinger on eight user-selectable frequencies.
The ATT-400ST variant features a built-in strobe light that blinks when interrogated, allowing for easier recovery under poor visibility conditions.
