Garmin Airmar P79 In-Hull Transducer

The Garmin Airmar P79 is a high-performance, adjustable in-hull depth transducer designed for easy installation and reliable bottom tracking without drilling through your hull. Perfect for boat owners who want accurate depth readings while keeping their hull completely clean and drag-free.

Suits all Garmin GPSMAP® and ECHOMAP™ fishfinders/chartplotters with 8 Pin connectors. It can also be used with 6 pin units when using the adapter part number G010-11612-00.

Features

• Dual-frequency performance: 50 kHz (45° beamwidth) for maximum depth up to 1,000 ft (305 m) and 200 kHz (12° beamwidth) for sharper resolution up to 600 ft (183 m). Delivers excellent depth performance in a wide range of conditions.
• Adjustable deadrise: Innovative design allows the transducer to tilt and lock from 0° to 22°, ensuring the sonar beam stays vertically oriented for the strongest echo returns regardless of your hull’s angle.
• Drill-free in-hull mounting: Mounts entirely inside the boat on solid fiberglass hulls. Simply bond the plastic base, fill with non-toxic propylene glycol (antifreeze), and lock in the transducer — no holes, no leaks, and no hull protrusions.
• 600W power rating: Provides strong signal strength and clear depth data for most recreational fishing and cruising applications.
• Depth-only transducer: Focuses purely on reliable depth information, making it ideal for pairing with your Garmin chartplotter or sounder.
