KEC-30G Electronic compass with KA-GC9A Heading Sensor



Onwa Electronic compass with 9 axis Heading Sensor and tilt mount. 



1 in stock (can be backordered)

The 9 axis Heading Sensor looks like a conventional GPS but the similarity ends there. Inside its IP67 case there is a very sophisticate device that can calculate SOG, COG, position and heading, pitch, roll and yaw and it does all of these rather well. From switch on, it gets a heading in just a few seconds. Coupled to the electronic compass an accurate course heading is shown at all times.
