I'm looking to buy a GPS. I dont know if I need to get a GPS?fishfinder or a good hand held. I've been looking at the 520c GPS and the Garmin Map 60cxs. I need to be able to run the boat in fog or night, fishin, duckhuntin or whatever the case may be. I've got a buddy of mines lil Garmin Vista and dont really rthink I coulod run at all with it (plained out). Ya im sure it would get there, I just wanna be able to run 20-25mph with it. I would also be getting the mapping for it, to were the Vista doesnt do that. I dont know a darn thing about any of this GPS stuff, just learning.

Any info would be greatly appreciated. Jon
