Raymarine A22154 Plastic TH DST800 Depth-Speed-Temp

The D800 is a Smart?, TRIDUCER multisensor that offers depth, speed, and temperature functions in one compact thru-hull fitting. Digital signal processing inside the housing provides depth, speed, and temperature data to a chart plotter, radar screen, or digital display, eliminating the need for a dedicated depth sounder. The wide port-starboard, fan shaped beam is able to find bottom even when installed on high-deadrise hulls or on sailboats when heeled.
