How much gas in case of accidental deco.

And, suggesting that people carry ponies because they don't know about gas management is just foolishness. It's like saying DIR divers carry wetnotes because they can't do hand signals.

That "suggestion" is your interpretation of my text...

Perhaps,

I just find it a bit odd when DIR divers can go on and on about the minutia of diving two or three stages, mixed gas and scooters but operating a pony on a rec dive overwhelms them. Maybe your philosophy finds it difficult to navigate such basic recreational issues because it was never designed to be used in a recreational setting.

F-1 racing has little to do with commuter traffic
Combat in Iraq has little to do with duck hunting
World cup Giant slalom has little to do with resort skiing

Why would anyone think the techniques and equipment used in highly technical cave penetrations has anything to do with recreational OW diving.

I have finally come to peace with DIR as I now see it as a self-consistent system (having all parts, ideas, actions, etc. consistent with one another). Extending the system to other forms of diving just creates needless strife.

Divers enjoy a very large range of choice as to dive instruction. They should keep in mind that this sport can, has, and will kill people. "You pay your nickel and you take your chances."

I wouldn't have it any other way...

I think the concept is to draw a method of 'best practice' from technical into recreational diving. The perceived benefit being an early-stagle 'indoctrination' into an appropriate mindset and approach, assuming the individual subsequently develops to technical level training.

I get the impression that DIR focused agencies absolutely assume that divers will eventually progress to technical/cave diving - which is probably true for them, given the demographic they attract. In contrast, non-DIR agencies don't make any assumptions about the student's ultimate goals or the inevitability of progression to tekkie status.

Using a pony doesn't "overwhelm" us.... it puzzles us ( at least it puzzles me). It is a solution that adds a marginal amount of time of breathing that isn't justified by the burden of carrying it around "in case you need it"... Something as simple as planning your dive trumps using a pony by a long shot in my simple way of thinking. And you do really not need to be DIR (I hate that acronym) for that.


When I carry a stage it is because I will be using it that dive. When I carry two, I will use both...

Some F1 technical developments are used in cars used for commuter traffic... Why not use technical diving techniques for rec diving ?


BTW.... these are no more than my personal views...

That wording normally means that a simulated decompression dive is acceptable. Simulated in the water, in NDL limits, that is.... not simulated on paper, or a computer screen....

I wasn't aware that any tech courses were/are available as theory only?!?! That seems like it might be incorrect...

In my world the point of carrying a pony in a rec dive scenario was to add a layer of redundancy, it was never part of the dive plan. The need for redundant gas in a rec scenario becomes crystal clear when a diver comes to understand that a cesa from depth is prolly surviveable, but there is a better safer way to get that done. We could discuss add nauseam the best way o add that safety because there are many, the pony botttle slung is just one of them, underwater dressage for the gold medal with your buddy is another, y valve, small doubles, and the list goes on.

Sorry about the dressage comment, nothing personal, I am in a 12 step program for my feelings about that and sometimes I slip.

The military sport bike rider course teaches you to hang off the bike in turns to keep the bike upright allowing you to carry more speed through a corner more safely.

This is a rider safety course to develop skills for the street...and it takes cues from...RACING?

There is no end to the examples of professional skills and practices crossing over into their recreational counterparts.



Why there is a constant need to draw a line in the sand and say if your recreational diver, your on my side, and if your a tech diver your not. This seems to me like the largest most fundimental way to confuse the crap out of new divers that are influenced by anything other than a vacation resort type of diving community.

Technical divers don't plan to finish a dive with 60% of the gas they started the dive with. Nor do they carry extra stages and deco bottles in case they accidentally completely ignore their dive plan.

Carry a small pony if you wish on your rec dive, but don't dive thirds and carry a spare 80 "just in case" you intentionally do everything wrong.
