The Raymarine P79 is a 600-watt adjustable in-hull transducer designed for fiberglass hulls. Its tool-free angle adjustment accommodates deadrise angles up to 22°, and only the base piece bonds to the hull — leaving no adhesive layer under the transducer face to dampen sound energy. The result is clean, direct sound transmission straight to the bottom with strong echo return. The transducer can be pulled in seconds for servicing or storage, and it pairs with the E66019 ST69 speed and temperature sensor for expanded data.
