I am looking into getting a 2nd unit for my boat. It currently has a hook2 3x on it, so I am going to stay with hook2 style. What size should I get? It would go on my console, do I get 5" for console and 5" for bow, or 7" console and keep the 3x at front? Either way the console would have all the goods on it with side scan, gps... Etc.

 

Thanks for the help

Personally I want the biggest screen where I spend my time (at the bow).  As for size get the biggest you can afford.
