It's a C80, the 120 would block my whole windshield, too big!

I like it, it is a nice unit. I'm probably going to upgrade to a BIG **** bolt-through-hull transducer this winter. The standard transom mount one is good but i want better. Don't get a shoot-thru-hull ducer unless you absolutely have to. I tried 1 and the bottom definition was POOR.
