Posted in the wrong place, but a previous poster had asked about map cards for Helix graphs.
My son has Navionics, apparently Lakemaster doesn’t cover Santee and a bunch of other lakes. He’s been very happy with it.
I use the Navionics in mine. It covers every lake in SC I fish and it covers coastal (inshore) waters I fish. I’ve heard good things about Lake Master but I’ve never looked into them to see what lakes they cover.
No matter how much it hurts, how dark it gets, or how far you fall…you are never out of the fight.
