Lake and inshore all-around saltwater fishing for small to mid-size outboard boats. RMS power: 600 W. 50/200 kHz. Easily adjusts to hull deadrise angles up to 22 degrees. This ensures that the beam is vertically oriented to receive echos, resulting in accurate depth readings. Unlike traditional "puck" type transducers, the P79 consists of a base that is bonded to the hull and filled with liquid. Separate transducer then attaches to the base with a twist lock. The sound waves travel more efficiently through the liquid, giving the best possible performance. No holes to drill. Depth only. Recommended for solid fiberglass hulls. Epoxies to aluminum hulls under 0.125" thick. Recommended for planing-hull power boats, trailered boats, rigid inflatable boats (RIBS) and racing sailboats. No hull protrusions. Boat size: Up to 25 feet.
