STI-350 Surface Acoustic Receiver

TThis rugged directional receiver provides both range and bearing to either the ATT-400 transponder or acoustic pingers operating from 25kHz to 45kHz. Designed for small boat operations, the STI-350 uses a directional hydrophone and adjustable staff assembly to locate underwater locations or targets marked with an acoustic beacon or ATT-400 transponder.

VADR-1000M and VADR-6000M Subsea Vehicle Acoustic Receivers

The VADR-1000M and VADR-6000M acoustic directional receivers are small but rugged passive pinger receivers used to assist operators of ROVs and AUVs in tracking acoustic sound sources from 25kHz to 45kHz. Both receivers use a RS232 protocol for communication to and from the surface. The VADR series receivers can also track the ATT-400 acoustic transponders and come in two operational depths, 1,000m and 6,000m.
