I want to upgrade my sonar and a combo unit is not that much more $. My question is my GPS now has a ext. antenna and I dont know if I get a combo with a internal antenna will they interfear with each other? I kinda like the Idea of having two gps,s.

Everybody needs 2 gps in a boat. One might fail..like my son's did down at Keaton Beach last year. He got lost...in a pea soup fog..after his gps failed. Only the aid of a compass saved his hiney...he headed due east till he hit land...at Dekle Beach. That's where we found him...anchored...at the end of a pier..with his wife blowing on a whistle. Turned out to be an electrical connection problem with the gps.
I don't think the two antennas will even know the other is on board.

Yeah, I can't see how they would interfer with each other, the antennas are only receivers and do not transfer any signal.

GPS antennas will not interfer with each other. Just as was previously said they are receivers not transmitters. No reason you can't have a back up unit. Now transducers are a different story, transducers of the same frequency would interfer with correct depth readings.
