NASA Electromagnetic Log - Data box & Easy Log

Feature

For a complete solution the EML-2 transducer and controller can be supplied together with a Clipper Easy log display

Speed through water with no moving parts.

The new EML-2 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.

With exellent linearity and a resolution of 0.1 Knot over the range 0.2 to 40 Knot the control box converts the sensor signal to boat speed trip and total distance and sends it to any compatible NMEA-0183 display.
