Navigation Speed Logs

SKIPPER manufacture all the Sensors to the SKIPPER Speed Logs. SKIPPER manufacture two different  Speed Log families, Doppler Speed Logs and Electromagnetic Speed Logs. The Doppler Speed Log consists of two versions based on the frequencies; 540 kHz and 270 kHz. 

Dual axis Doppler Log DL850 indicates speed in dual axis in water and above bottom, it could even indicate speed in three axis (Docking function), both for water speed and speed above bottom. DL850 have built in echo sounder and watertemp readout. SKIPPER EML224 is a dual axis elektro magnetic log which indicate speed in dual axis and sea water temperature. The EML224 is now also available with a Compact Display in 1 or 2 axis. Both systems are wheelmark approved. 

SKIPPER EML224 COMPACT
The SKIPPER EML224 Compact is the newest Electromagnetic Speed Log. The difference from the EML224 Graphic is that the operator unit (display) is smaller. The EML224 Compact is available in single or dual axis, making it more flexible depending on customers needs and demands. 

SKIPPER EML224 Graphic
The SKIPPER EML 224 is a dual axis speed log, working on the electromagnetic principle. It is providing longitudinal and transversal ship speed relative to sea water. The EML 224 gives accurate navigation parameters, measured as they happen, and presented in a logical, user friendly way. 

SKIPPER DL850 270 kHz
The SKIPPER DL 850 is a dual axis speed log, working on the Doppler principle with 270 kHz transducer. It is providing longitudinal and fore/aft transversal ship speed relative to the sea bed or the water. The DL 850 provides accurate navigation parameters measured as they happen, and presented in a logical, user friendly way. 

SKIPPER DL850 540 kHz  
The SKIPPER DL 850 is a dual axis speed log, working on the Doppler principle with 540 kHz transducers and a 270 kHz transducer for the Echo Sounder function. It is providing longitudinal and fore/aft transversal ship speed relative to the sea bed or the water. The DL 850 provides accurate navigation parameters measured as they happen, and presented in a logical, user friendly way.
