Product details

NASA's innovative electromagnetic log sensor gives you precise information about speed, distance travelled and other journey data. The log measures speed through the water with no moving parts, but via an alternating magnetic field.
The robust, accurate sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water. The supplied control box converts the sensor signal to a pulse output to connect to the display.
Supplied with log sensor, Clipper series display and databox.

Also works fine in an Aluminum hull

In spite of the guidance that it only works in a GRP hull, we installed it in our Aluminum hull and it turns out to work fine. Of course when there is fouling the speed reads a little slower (more so than the SOG), but this is a good reminder to dive and clean the hull, and unlike those stupid paddlewheels a stiff brush is all you need for it to read cleanly again!

Interesting technology

Replaces the ever-clogging wheel with the log giver.

4/29/2026 Variant: 80245 in use on a Sirius Werft GmbH - Sirius 26

good thing

While not completely resistant to fouling, it's significantly better than the usual dials.

A disadvantage is that the system displays noticeably different speeds when the water flow isn't straight. On the starboard tack, my boat is half a knot "faster" than on the port tack (at the same GPS speed). I suspect this is because the water flows differently around the sensor in each direction.
