I have paper charts of most lakes, but I will take a GPS over paper any day
my maps also work on the computer so I can plan my day and put a waypoint or routes on the computer and upload it to my gps and drive right to it rather then looking at the paper map while drive to the spot
I knew simcoe like the back of my hand but to find the one finger on cooks bay often took 1/5 an hour to find
now point and click and I am there......gps changed fishing for me...now if only I had a working boat to go with the gps
