Furuno 1623 Radar

Found a sale at a local supplier who was selling a display model of the Furuno 1623 Radar. Added in a GPS antenna for the radar unit and a back-up GPS antenna that will go in the boat as a secondary navigation aid. Rarely will radar be needed so a small simple positioning GPS readout will be used. Low power and simple to use.The radar dome sees up to 16NM, (30kms / 18.5m)

I'm not crazy about the display being black and white, but power consumption is the key here, 12v @ 4amps (about 50watts to power the device with radar on)

I have no compass attached to the NEMA connections, but the GPS seems to give me course info. Do i need a compass? or is the GPS capable of giving me all the course info i need? any input would be awesome!

The entire set-up...

The display with positioning data only...
