sub $500 down imaging fish finder/gps help
The lowrance console fishfinder on my 17 foot 1985 charger bass boat seems to have bit the dust. I want to replace it with a down imaging fish finder/gps combo. While I wish I could spring for a nicer unit, my finances are limited to sub $500 so I know I am looking at 4-5 inch unit. I want one that swivels so I could view it from the front or the back of the boat, which seems to eliminate the humminbird helix (yes I know I could get a ram mount- but why didn't humminbird make a swivel mount like other manufacturers? too logical I guess). Most of the lakes I fish are not on a chip, so I am very interested in mapping them myself which seems to leave me down to Garmin and Lowrance. Am I over analyzing this? Which sub $500 unit would you choose? Thanks in advance!
