The Airmar P79 NMEA 2000 In-Hull 235 kHz is a depth transducer engineered for high-performance boats seeking a clean, hull-friendly installation with dependable depth readings.
-
Installation Type: In-hull installation using a liquid-filled hull interface; transducer twists into place on a hull-mounted base, with no holes to drill and no external hull protrusions.
-
Deadrise Adaptability: Adjusts to hull deadrise angles up to 22°, keeping the beam vertically oriented for accurate echo returns across varying hull shapes.
-
Frequency & Beam: 235 kHz frequency with an 11° cone for optimal depth performance in deep and shallow water ranges.
-
Depth-only Operation: Dedicated to depth measurement, simplifying data output for compatible displays and chartplotters.
-
Hull Compatibility: Recommended for solid fiberglass hulls; epoxy to aluminum hulls under 0.38 mm (0.150”) thick, broadening installation options.
-
Compatibility & Applications: Suitable for planing-hull power boats, trailered boats, rigid inflatable boats (RIBs), and racing sailboats.
-
Connectivity: Includes a 6 m (20 ft) NMEA 2000 cable & connector for networked depth data across compatible marine electronics.
-
Protection & Design: No hull protrusions and a hull-friendly interface protect the transducer while minimizing drag and impact risk.
-
Manufacturer & Model: Manufacturer: Airmar | Part No: P79-235-N2
By bonding to a hull-mounted base with a liquid-filled interface, the P79 delivers efficient sound transmission and reliable depth readings while maintaining a smooth hull surface. Its adjustable-angle design maintains a vertical beam across different hull deadrises, making it well suited for RIBs and racing sailboats where a low-profile, durable depth solution is essential. The included NMEA 2000 connection simplifies integration with your marine electronics, providing seamless depth data to chartplotters and displays on your vessel. Note: This product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns.
