Just bought a HDS-5 base-us model. Now realizing for about $50 more, I could have had the lake insight preloaded. how good is the insight? worth the extra $$ or do I put it towards a navionics chip? I can send it back and exchange it. I just need contours(would like structure and trees), I think the base map has that, but I haven't hooked it up to see yet. Already sent back an elite5 when I found out there is a rebate on the hds and it was only 50 more after that.
