Raymarine P79S Smart Depth In Hull Depth Transducer with Fitting Kit, NMEA2000

The Raymarine P79S is a smart, NMEA 2000 in-hull depth transducer that reads through a solid fibreglass hull with no protrusion whatsoever, making it ideal for trailered boats and owners who want to minimise drag. It comes with the P79 fitting kit: an adjustable flange that bonds to the inside of the hull with quick-setting marine epoxy, is dialled in to match the boat's deadrise angle, then filled with non-toxic antifreeze before the active transducer cap is locked in place for a straight-down beam.

The P79S provides digital depth data over a DeviceNet NMEA 2000 connector, plugging directly into your network for display on connected instruments and chartplotters. It operates at 235 kHz, offset from the 50/200 kHz fishfinder band to avoid interference, and accommodates deadrise angles from 2 to 22 degrees. As an in-hull design it has no water-temperature sensor and is intended for solid fibreglass hulls up to 5/8 inch thick (or aluminium under 3.8 mm).
