The DT800 is a smart depth and temperature transducer for Raymarine chartplotter and instrument systems. The convenient SeaTalkng output allows you to connect the transducer directly to your network and receive accurate depth and water temperature data on connected devices. Calibration of the transducer sensors is performed by a networked Axiom chartplotter or i70s instrument. 0° (flat) or 12° slanted element options available. 235 kHz frequency prevents interference with other onboard depth sounders or fishfinders. 100-Watt output provides accurate depths from 0.5 m (1.6 ft) to 180 m (600 ft). 2-inch high-strength plastic housing fits fiberglass or metal hulls. Retractable housing with water valve for easy maintenance. 6 m (20 ft) interconnect cable with SeaTalkng connector.
