Doppler Log 

SKIPPER DL 850 speed log system is the latest in computerbased speedlog technology for use onboard merchant- and larger fishing vessels. 
DL 850 is a dual axis speed log, working on the doppler principle. It provides information about transversal and longitudinal ship speed plus possible drift speed and angle. 
DL 850 gives information on both speed over ground and through water. 
DL 850 has a backlit, colour LCD display with «Soft-Keys» to choose between different screens. The operator can choose between several screens and through this obtain all necessary information concerning speed and drift. 
DL 850 has a built-in echo sounder function for depths down to 100m, with the possibility to measure current in three depth layers down to 50m, and reading of sea temperature. 
The system may be interfaced with most modern peripheral equipment.
