:doctor: To all the DIR and non DIR divers out there! I dive a Zeagle BP and wings (of course my wings with redundant bladder is custom with a prototype BP panel) I have a Zeagle drysuit and original Zeagle Apeks regs Heck I'm the Zeagle poster child (Please Note I do not use their fins and they know it) Dacor Mask but I do have a Zeagle as back up. Example - By the equipment comments of the DIR idealism for example I do not dive DIR. Because My harness has quick release buckles on the shoulders.These could be a breaking point. OK so can straps break if poorly maintained. Does DIR consider those people who have had shoulder injuries and kitting up difficulties with using a strap harness. Having more than 10K logged dives, most of which is overhead I have yet to see a diver lose a tank set short of a tank falling out of loose tank bands, could it happen I suppose it could worst case scenario. My long hose is very easily deployable, I have been told my rig is very clean. Yet you would say I'm not DIR. As I said before I am sure I will learn something if I took a DIR-F class. So what are the skills they review in the DIR teachings?
