DL 1 – Single Axis Doppler Speed Log
The SKIPPER DL1 measures the speed of the vessel through the water at all times and in any depth. The system includes a single sensor mounted in a tank or sea valve. The display housing can be
mounted anywhere on the bridge and a connection box can be placed wherever it is most convenient for connection. A COM port within the connection box allows for easy installation and diagnostics from a laptop with a RS-232 COM port.
DL 1 – Multi Axis Doppler Speed Log
The SKIPPER DL1 is a single axis speed log system, working on the Doppler principle, providing longitudinal ship’s speed and distance relative to sea water. The SKIPPER DL1 gives accurate
navigation parameters measured as they happen and presented in a logical user friendly way.

DL 2 Doppler Speed Log
The DL2 present the critical parameters on a touch screen and can be interfaced with bridge systems and repeaters. The DL 2 can also present distance traveled, depth and water temperature.
Doppler technology is commonly considered the gold standard of speed measurement as it measures remotely, (away from the effects caused by the vessel itself) and once installed, it operates even with considerable organic growth on the transducer.
DL 21 Doppler Speed Log
The new SKIPPER DL 21 is a speed log, working on the Doppler principle, providing Speed through water (STW) and Speed over ground (SOG) in 2 axis. The DL21 Speed Log is designed for ships over 50.000 GT with simultaneous and independent measurement of speed through water and speed over ground to comply with the requirements of MSC.334(90), amendments to performance standards for devices to measure and indicate speed and distance.
