Airmar P79 NMEA 2000 In-Hull 235 kHz

Enhance your vessel's navigation precision with the P79 NMEA 2000 In-Hull 235 kHz Transducer. Engineered for optimal performance and effortless installation, this transducer is a must-have for boating enthusiasts seeking reliable and accurate depth measurements.

Advanced Adjustable Angle Design

The P79 in-hull transducer features an innovative adjustable-angle mechanism that accommodates hull deadrise angles up to 22°. This ensures the sonar beam remains vertically aligned, maximizing echo returns and delivering precise depth readings regardless of your boat's hull shape.

Superior In-Hull Construction

Breaking away from traditional "puck" transducers, the P79 boasts a sturdy base bonded directly to the hull and filled with high-quality liquid. The separate transducer unit securely attaches to the base using a twist lock system, facilitating efficient sound wave transmission and enhancing overall performance.

Optimal for Various Hull Types

Designed for versatility, the P79 is ideal for a range of boats including rigid inflatable boats (RIBs), racing sailboats, planing-hull power boats, and trailered boats. Its in-hull installation ensures no protrusions, preserving your boat's hydrodynamics and aesthetic appeal.
