Target Electromagnetic Speed Log

The Target electromagnetic speed log measures the boat speed through the water with no moving parts.

Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. It is designed for installation into most types of GRP hulls.

With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the log sensor sends signals to a control box which then converts the sensor signal to boat speed, trip and total distance. This data is transmitted in NMEA 0183 format to a new Target EM Log display unit.
