Handheld gps
I have an H20c and I just got the Navionics card and I like it. The only thing that I don't like is it does not have the roads on it so you have put your other card in until you get to the lake or are looking for streets. But it shows a lot of detail on the water. I like the Lowrance gps. I have had it since last year. Hope that helps.:D
But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus.
