GPS COMPASS KGC-222

─ Features ─

• KGC-222 consists of two main components, display and antenna. Display unit has processor, receiver and LCD display built-in. 

• KGC-222 has internal electronic compass as backup sensor. This enables the backup sensor to output heading even if the GPS signals are interrupted in such case as the vessel passing under a bridge. 

• KGC-222 can also output pitch / roll and heaving data. When KGC-222 is used with an echo sounder with heaving compensation function, you can obtain stable sea bottom without effect from heaves and waves. 

• It has 3 heading data output ports. Up to 5 ports will be available with connecting optional junction box.
