Northstar AA002028 Fishfinder Transducer B164-20-6N

The B164 is a 1kW through-hull low-profile depth and temperature transducer with a bronze housing, that operates at 50kHz and 200kHz. It has a fixed (non-retractable) insert. This transducer is ideal for fast, trailered, tournament, sport-fishing boats that cannot install an external fairing.

This version has a Northstar/Navman 6-pin connector and is sold by Northstar as part AA002028.

The 20 deg tilt transducer is suitable for deadrise angles from 16 deg to 24 deg. The ceramic element is tilted inside the transducer to compensate for the boats deadrise (angle of the hull). This aims the beam directly at the bottom for accurate readings.
