The Skipper DL 850 Dual Axis Speedlog has a 10.4inch colour LCD display and provides longitudinal and fore/aft transversal ship speed relative to the seabed and water simutaneously. Remote speed data is available by adding an IR 300 Digital Speed Repeater. The Skipper DL 850 270KHz version operates at lower frequency tracking botom speeds at greater depth. Both are IMO approved.
There is a full range of speedlog sensors, sea valves and tanks to suit all vessel applications.
