Upgrading Depthfinder to Combo suggestions-Helix7?

[bfisherman11]

Maybe not the best place to ask but my dad has offered to upgrade my 560 Hummingbird depthfinder to something with GPS and lake mapping. I see a lot of resorts use Lowrance units. Not that familiar with them.... Am more familiar with HB. My gut says the HB Helix 7 DI GPS-Chartplotter w/Navonics might be the right unit for me. I mostly fish the US side of Rainy and also Kab.

Really want a good depthfinder/fish finder and good lake mapping.

What do you all like and how does it work on Rainy?

Oh, just decided on going back up on 8/13 with the wife. going to tough it out with the 560 this trip but a unit with lake mapping would be nice to help me find the reef's

thanks,

Bill

Lakemaster is spot-on for Rainy

I got the navionics. Looks good. Oh, did get the Helix7 GPS and SI.
