Well I got my 1198c si delivered. I can hardly wait to get this thing in the water and I am surrounded by nothing but ice! Going to replace my 898. the 898 will be on the trolling motor, linked by Ethernet with the 1198. Moving Puck for 898 to the bow also for more accurate gps. Puck for 1198 will go on rear gunnel for more accurate gps also. (maybe overkill?) I fish Indiana mostly, trips to Canada, Wisconsin and Kentucky. Anyone have experience with the sonar chips or would I just be better off with the std. navionics. Mounting on a Lund 1850 Tyee. Probably a Ram Mount. Going to have the marina do the install in a couple weeks. Am I forgetting anything? I am excited!!!
