As mentioned above but my two cents for what it is worth, I would go with the Humminbird Helix Gen 3 or Gen 4 in the biggest screen I could afford 10 inch minimum. This gives you some options Mega 360 and Gen 1 Megalive which both can be had for pretty cheap now. I have both and my Megalive Gen 1 I am more then satisfied for how it performs for me and the Mega 360 makes using the Megalive even easier in finding structure and suspended fish then fishing that structure or fish with Megalive.
