I would like to thank Larry from scubatoys for the great program Table Tudor. He is kind enough to give the program to any scubaboard members for free and it is a great training aide or to practice using the dive tables. It has 9 different tables to choose from and I use the Navy tables as I am heading in the technical diving direction and they also list deco stops for extended range diving. when I get there with the cave diving I am looking to do this fall. If you havent checked out this program yet give it a try...Thanks again Larry for a great product...Toolbox
