Product Name Notes
DX900+ Multilog Smart™ Electromagnetic Speed & Temp Sensor Say goodbye to the paddlewheel and hello to technology. The DX900+ uses electromagnetic technology to accurately measure dual-axis speed-through-water plus immediately calculate leeway travel. Paddlewheels need cleaning and only measure...
ST300 Speed and Temperature Sensor Thru‑hull The ST300, speed and temperature sensor is low in price and short in size. As part of our Shorty™ Series, it is designed for boats with limited headroom. The...
ST61 Speed and Temperature Sensor Transom Mount The ST61 consists of a paddlewheel speed carrier that snaps into a small transom housing containing sensing electronics. This standalone unit gives accurate speed readings over a wide speed range.
ST63 Speed and Temperature Sensor Transom Mount The ST63 easily adds speed and temperature to any analog display. It is used with instruments that allow separate depth, speed, and temperature inputs. Both the paddlewheel and electronics are...
ST69 Speed and Temperature Sensor Transom Mount The ST69 is the ultimate, high-speed, transom-mounted sensor. The paddlewheel and housing do not project below the hull which minimizes spray and drag. And the design protects the sensor from...
ST800 Smart™ Speed and Temp Sensor Thru-hull The ST800 speed and temperature sensor processes digital signals inside the thru-hull housing. Then this Smart™ Sensor sends data to a chart plotter, radar screen, or digital display in...
ST850 Smart™ Speed and Temp Sensor Thru-hull The ST850 is a low-profile, retractable, thru-hull sensor that computes accurate speed and temperature data and sends it to any NMEA 0183 or NMEA 2000® display or network. These low-profile...
