SKIPPER SD21 Speed over ground (SOG) Speed log with built in STW sensor

The SKIPPER SD21 is a Single Axis Doppler Speed Log and a Dual Axis SATLOG Combined. It is designed to meet the IMO resolution MSC334(90) that require two separate speed logs for vessels above 50 000 dwt. The SKIPPER SD21 gives accurate navigation parameters, measured as they happen, and presented in a logical, user friendly way.
