Location: Gilberts IL/Rhinelander WI | So I saw the navionics at Icast video and am intrigued by the sonar part, has any one used the gps/sonar to essentially make your own depth contours of lakes?
I fish a lot of lakes in northern wisconsin that have no info on the chip, some even showing the boat on land. I feel as though it has been out for a while, but haven't looked into it.
I'd be using an HDS unit, how does it work? What do I need to purchase? |
