I saw that .... Lake Fork is the main lake needing a boat trail and it seems to be mapped well. I used to go to Fork when it was so full of trees you had trouble trolling ..... saw a guy get his motor knocked off along with part of his boat.
My HDS-9 Gen 2 touch I just bought was a floor display and had Navionics already installed and I didn't even know it. I bought Lake Insight Pro v16 and installed it before I found out .... now I have both, and will tell you which one is best on Lake Palestine tomorrow.
BOTH MAPS SUCK!!! I zoomed in and out with both maps and saw no detail ...... Found two brush piles I marked while exploring, so I guess they are good for that!
