Navigation Speed Logs



The SKIPPER DL2 is a Dual Axis Doppler Speed Log, working on the doppler principle, providing longitudinal and transversal ship’s speed (STW and SOG) and distance relative to sea water. The SKIPPER DL2 gives accurate navigation parameters, measured as they happen, and presented in a logical, user friendly way.
