The DST800 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. One hole in the boat's hull makes this TRIDUCER® Multisensor attractive to both boat builders and boat owners. And the retractable multisensor is available with NMEA 0183, NMEA 2000®, or custom CAN protocols. The wide port-starboard, fan shaped beam is able to find bottom even when installed on high-deadrise hulls or on sailboats when heeled.
