Our P79 in-hull transducer 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, 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.Works with the Lowrance HDS Series and Simrad NSE Series Multifuction Display units.FeaturesDepth 50/200 kHz 600 W RMS Mid-performance Plastic 7 Pin Blue Connector Specifications: Temperature: No Speed Included: No Pins: 7 Mounting Style: In-Hull Box Dimensions: 2"H x 7"W x 8"L WT: 2.7 lbs UPC: 421945336052 Owner&';s Manual (pdf)Brochure (pdf)
