Question for you hummingbird guys. I am a diehard lowrance guy and have been for a while. I am slightly considering thinking about getting a Helix mega unit. 1 thing I was wandering and haven't been able to find an answer to. Can you set a page up to have the bottom half as SI and the top half a split between gps and sonar or gps and di? I haven't seen anything that shows the ability to edit a page layout and that is kind of a deal breaker for me. I am considering the helix units because you can get more screen for a considerably less amount of money. Being able to get 1 mega imaging unit and have the cheaper sonar/gps units on the network display this imagry is lucrative to me. I could sell my gen3 units used and buy brand new without coming out of pocket. I don't want to be disappointed though.
