GARMIN Galvanic Isolator Kit for GT17M-THF Transducer
The GARMIN Galvanic Isolator Kit is designed for the GT17M-THF transducer to prevent galvanic corrosion in marine environments. This kit is crucial for installation by marine technicians to ensure the transducer’s optimal performance and longevity.
Compatibility & Applications
- Fits GT17M-THF transducer installations on sailboats and motor yachts.
- Prevents galvanic corrosion in saltwater applications.
- Mounts in-line with transducer wiring for effective isolation.
- Wires to the transducer’s power and ground connections.
- Replaces previous galvanic isolators from GARMIN and similar brands.
- Integrates with NMEA 2000 networks for enhanced connectivity.
The kit significantly extends the lifespan of the GT17M-THF transducer by mitigating corrosion risks associated with metal components in marine environments. Installation typically occurs in the transom area to protect the transducer’s wiring, differentiating this unit from generic alternatives by its specific design for the GT17M-THF model.
