I just bought a humminbird 787c2 that is GPS capable and was wondering which chips offer the best details for them.  I fish out west.  Any suggestions would be apreciated.

Thanks

I went to the local Bass Pro Shop and they installed the different chips in a unit like mine and let me see the differences, and there was a big difference on the east Tn lakes. You may try BPS, Cabelas, West Marine or possibly local boat dealers. Not sure if the local dealers are willing but the guys at BPS were more than willing and very helpful. I would be afraid to recommend a chip for another area as the detail may be different. The biggest difference I saw was depth contours and land (bank) detail. If none of these are available talk to other fishermen at local tournaments or tackle shops. Good Luck
