Directional Receiver
Description
The Seeker acoustic directional receiver is a small, rugged passive pinger receiver, used to assist operators of ROVs and AUVs in tracking acoustic sound sources (from 25 to 40kHz).
There are two different models of Seeker receivers. The VADR1000M operates to depths of 1000 metres and the VADR6000M can withstand depths of 6000 metres.
