The SKIPPER DL21 is a Dual Axis Doppler Speed Log and a Single Axis Doppler Speed Log in one sensor unit. It is working on the doppler principle, providing longitudinal and transversal ship’s speed (STW and SOG) and distance relative to sea water. The SKIPPER DL21 gives accurate navigation parameters, measured as they happen, and presented in a logical, user friendly way.

The new DL21 Speed Log is designed for ships over 50.000 GT with simultaneous and independent measurement of speed through water and speed over ground. This is according to new IMO resolution MSC334(90).
