Compatibility & Applications
- Mounts inside the hull as a depth transducer installation.
- Wires to sonar equipment through a 20 ft cable.
- Pairs with Garmin hardware using an 8-pin transducer connection.
- Fits systems requiring CHIRP operation from 145 to 230 kHz.
- Includes plastic housing for an in-hull depth-sensing location.
- Pairs with High Wide CHIRP sonar frequency coverage.
A documented installation scenario is an in-hull depth transducer run where the 20 ft cable reaches Garmin sonar hardware with an 8-pin port. Its differentiator from a generic depth transducer is the listed High Wide CHIRP band across 145 to 230 kHz.
