P79 In-Hull Transducer w/Humminbird #9 Plug – 7-PinOur P79 in-hull transducer easily adjusts to hull dead rise angles up to 22. This ensures that the beam is vertically oriented to receive echoes, resulting in accurate depth readings. Unlike traditional “puck” type transducers, our P79 consists of a base that is bonded to the hull and filled with liquid. The separate transducer then attaches to the base with a twist lock. The sound waves travel more efficiently though the liquid, giving the best possible performance.Features:Adjusts to hull deadrise angles from 2 to 22No holes to drillDepth onlyRecommended for solid fiberglass hullsAdheres to aluminum hulls under 3.8 mm (0.16″) thickRecommended for planing-hull power boats, trailered boats, rigid inflatable boats (RIBS), and racing sailboatsNo hull protrusionsBoat Size: Up to 8M (25′)Specifications:Weight: 2.3kg (5lb)Hull Deadrise: 0 to 22 Acoustic Window: Layered plastic urethaneThis product may not be returned to the original point of purchase.
