Strength member terminated in a soft eye to fasten to your vessel. 10 feet of audio cable from soft eye to audio and power connections*.

*If you require more than 10 feet of audio cable from the soft eye to the audio and power connection then please email your length to This email address is being protected from spambots. You need JavaScript enabled to view it. after placing your order.

This model has two MODES:

1. Long Distance HIGH GAIN with Automatic Gain Control and

2. Short Distance LOW GAIN with NO Automatic Gain Control.

The first mode is used to listen to creatures at a distance with no powered boats operating in the area. The second is used when other powered boats are close by. A contact at the surface end of the cable sets the MODE.

In addition to the plugs connecting to your ship board stereo amplifier system, a red wire connects to the stereo 12 Volt positive source. This supplies a low current bias to the hydrophone active electronics.
