"Garmin P79 600W In-Hull 50-200kHz for GSD-24 (010-10327-20) Brand New Includes One Year Warranty, The Garmin 010-10327-20 is an Airmar P79 8 Pin adjustable in-hull transducer that easily adjusts to hull deadrise angles up to 22°
This ensures that the beam is vertically oriented to receive echos, resulting in accurate depth readings. Unlike traditional ""puck"" type transducers, the Airmar 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. This adjustable in-hull mount transducer provides depth data. It has an operating frequency of 50 or 200 kHz and mounts on a 0-22° deadrise angle. 010-10327-20 Features: Plastic In-hull Transducer (8-pin), Provides Depth Data, Operating Frequency 50 & 200 kHz, Adjustable Transducer, Mounts On 0-22° Deadrise Angle, Includes Installation Instructions, For Garmin GPS Models: GSD&trade 24"
