I am just getting back from a week camping at Flamingo. I got a chance to really put Glen's chip (FMT) through it's paces. We were running 65 to 93 miles each day. We fished from outside the reef line in Islamorada during a day we decided to visit the keys and then all through Florida Bay, up the coast to Lostman's and even a little on some gulf wrecks. For the offshore we used the Navionics charts but for everything else we used the FMT chip. It was very interesting comparing Glen's tracks to the routes I traditionally run. He and I are pretty much in agreement for everywhere I went in Florida Bay. Going up the coast from the Harney and north Glen's tracks are far supperior to my traditional trails in and out of those areas. Sticking with his tracks I was in good depths the entire time even on the lower ends of the tides. Some of my routes had me running aground from time to time and I don't go up there enough to tweak the routes just right. Now I don't have to, I will just follow his trails from now on.
The satelite photo's are far superior to the others I have used as well. For Florida Bay you can just use the photos and not really worry about the trails.
