I'm thinking of upgrading my front unit to a combo, only have sonar now, use a handheld Garmin for gps. Wannabe, thanks, sent me an old FHS chip for my Garmin GPSMAP 76Cx but it does not have Okatibbee creek on it. Scott has a LMS (I think) with the base map according to Sac and it does have the creek on it and it has maybe spoiled me, now I want that on my boat. So what combo units with chips do you have and can you tell me if they show Okatibbee with the creek where I do 90% of my fishing. I haven't been able to find a site that lets you pick and look at what is on the chip. Would like MS and Ala for sure. Having the creeks on there sure makes it easier to follow. Sure would be nice to be able to see a pix of the lakes you mainly fish on the map sites.
