VADR-6000M Subsea Vehicle Acoustic Receiver
6,000 m rated directional pinger and transponder receiver for ROVs and AUVs, tracking 8–45 kHz sources, with RS232 surface interface.
Description
The VADR-6000M acoustic directional receivers are small, rugged passive pinger receivers that help ROV and AUV operators track acoustic sound sources from 8 kHz to 45 kHz. They can also interrogate ATT-400 transponders and communicate with the surface over RS232.

- Interrogation frequency 26 kHz; system range up to 750 m (2,461 ft)
- Beam width 40 ± 5° conical
- RS232 control interface; input 18 to 32 VDC (24 VDC nominal)
- Hard-coat anodized aluminum housing rated to 6,000 m (19,685 ft)
- 12.7 cm diameter x 28.0 cm long; 6.8 kg in air / 5.5 kg in water
Applications
Locating pingers and transponder-marked targets with ROVs and AUVs.
