For all you fishermen/women, I just downloaded navionics lake maps to.my phone. It is shweeet!!
I have the 250$ lowrance h20 I use for fishing, this provides just as much detail. In addition, my phoned has a larger screen and way higher resolution. I can also geotag with pictures using my camera. I am pretty psyched. I can't believe I got all that functionally in that app for 12$.
Guess mug lowrance is going on ebay
