VADR-6000M Subsea Vehicle Acoustic Receivers

Description

The VADR-6000M acoustic directional receivers are small but rugged passive pinger receivers. The unit assists ROV and AUV operators in tracking acoustic sound sources from 8kHz to 45kHz. The receivers use an RS232 protocol for communication to and from the surface. The VADR series receivers can also track the ATT-400 acoustic transponders and have operational depths of 6,000m.
