Raymarine P79, 600w In-Hull Transducer - E26001-PZ

The Raymarine P79 In-Hull Transducer (E26001-PZ) is a mid-performance 600W sonar solution designed for boaters who want accurate depth readings without drilling holes through their hull. It is specifically engineered for solid fiberglass hulls and is a popular choice for trailered boats or high-performance vessels where minimizing drag is essential.

Key Performance & Design

The P79 features a unique liquid-filled base that is bonded to the inside of the hull. This design allows sound waves to travel efficiently through the liquid and the fiberglass, providing better performance than traditional "puck" style transducers. It is a depth-only sensor, meaning it does not provide water temperature or speed data.

• Adjustable Deadrise: The innovative flange design easily adjusts to accommodate hull deadrise angles from 0° to 22°, ensuring the sonar beam is always pointed straight down.

• Drill-Free Installation: Because it mounts entirely inside the boat, there are no hull protrusions, reducing drag and eliminating the risk of damage from floating debris or trailer bunks.

• Dual-Frequency Operation: It operates at 50/200 kHz, offering a balance between deep-water tracking (up to 1,000 ft) and high-detail resolution in shallower water.

• Easy Maintenance: The transducer features a twist-lock attachment that allows the sensor to be removed from its base in seconds for servicing without affecting the hull seal.

Technical Specifications

• Part Number: E26001-PZ (often associated with ST60/i50 instruments)

• Power Output: 600W RMS

• Frequency: 50 kHz (45° beam) and 200 kHz (12° beam)

• Compatibility: Optimized for Raymarine i40, i50, iTC-5, and legacy ST60+ systems.

• Hull Requirements: Solid fiberglass only (Max thickness 5/8"). Not compatible with cored hulls, wood, or metal.

Installation Tip: To ensure the best signal, the mounting area must be free of air bubbles or coring material within the fiberglass. If you need to connect this to a modern NMEA 2000 network instead, I can find the Raymarine P79S Smart Transducer for you. Would you like to see that version?
