*Floater*:It wasn't an obvious decision for me because for the same price I could have taken TDI's adv. nitrox/deco procedures, but I was impressed by the control and techniques demonstrated by DIR divers on the clips I saw,
These courses aren't comparable. TDI Deco Procedures is a deep air course (to 150 feet) and you need to be a sound diver to take this course. A better comparison could be made to Cavern and Fundamentals.
