Description
Raymarine P79S Smart Sensor Depth | Boat Supply Store
This depth-only transducer eliminates hull penetrations by mounting internally on solid fiberglass hulls up to 8 meters. It delivers processed depth data directly to your NMEA 2000 network with 60W power output and a 235 kHz frequency, preventing interference. The unit utilizes an antifreeze coupling for optimal signal transmission through the hull, ensuring accurate readings without external protrusions.

Common Concerns Answered
How does the in-hull installation affect accuracy compared to thru-hull transducers?
The P79S utilizes an antifreeze fill and is specifically designed for solid fiberglass hulls to optimize signal transmission, mitigating potential signal degradation common with some in-hull installations. Careful placement and calibration are essential for peak performance.
What are the limitations of the P79S sensor?
This sensor is exclusively for depth readings and does not provide temperature or speed data. Optimal performance requires precise placement and calibration during installation.
Will the P79S interfere with other sounding devices on my boat?
No, the P79S operates at a 235 kHz frequency, a band specifically chosen to prevent interference with other common echo sounder frequencies.
