I love my Helix 5. It works as advertised. Its a lot smarter than me though. I takes some time on youtube and here on TFF learning how to use it and understand what all it can do.
The only thing I don't like about it is the 5" screen. I wish I had the 7. On a bright sunny day I have a hard time seeing the detail on the screen when on 3d or SI mode.
The main thing you are not getting with the 5 or 7 is the auto navigate abilities like with Ipilot where you link your unit up with your engine or trolling motor. There are some other bells and whistles the more expensive units have the Helix series don't. But your structure scan, SI, sonar etc all works the same. You wouldn't be disappointed with either one of them.
If it ain't yours don't mess with it!
