Guys,
I am buying what will probably be my last boat. Due to not getting any younger an my wife's balance issues we are getting a pontoon. I want to set this up for fishing as much as possible. I have pretty much decided on the Ulterra 80# thrust 60" shaft I Piolt link. Also installing the Minn Kota quick remove bracket. Here's where I need help I have been reading up on depthfinders. The more I look at them the more confused I get. I have been looking at the Hummingbird Helix 10 si & 12 I have also looked at the Onix 10 si. Does anyone have these models and would recommend them? Or should I be looking at something different? Also any set up suggestions would be appreciated.

Thanks
Kevin
