Still looking at up front sonar screens. I noticed that only the 917c is the last of the big screen 7 inch that is listed on HB products page. I guess it is soon to be replaced by the 957c( when the production parts play out on the 917c). Looks like it is on its last run. Hate to spend a 1000 bucks on something that is doomed to obsolesce in such a short time. Humminbird probably keeping 917c as an active product to finish out the parts run.

I guess I am being pessimistic.
