Airmar P-79 In-Hull Transducer


Our P79 is a dual-frequency, depth-only, in-hull transducer that easily adjusts to hull deadrise angles up to 22°. The P79 includes a plastic mounting base which is aligned to the centreline and secured inside the hull. Then it is filled with non-toxic antifreeze. The transducer is inserted into the base and adjusted for the proper deadrise offset, ensuring the beam is shooting straight down for maximum echo returns. The eco-friendly coolant provides the best medium to transmit through solid fiberglass and into the surrounding water. The major benefit of in-hull transducers is no protruding features on the exterior of the hull, making it the perfect choice for trailered or lifted boats. Designed for smaller boats up to 8 m (25′) with a solid fiberglass hull.
