"Standard Horizon DST525 Brand New Includes Three Year Warranty, The Standard Horizon DST525 adjustable in-hull depth angle transducer easily adjusts to hull deadrise angles up to 22° which ensures that the beam is vertically oriented to receive echos, resulting in accurate depth readings
Unlike traditional ""puck"" type transducer, only the base piece filled with liquid, is bonded to the hull and the separate transducer then attaches to the base with a twist lock. There is no adhesive layer under the transducer face to absorb sound energy. The sound waves travel more efficiently though the liquid, giving amazing performance.
