Disadvantages of DIR ?

[-hh]

Just to put a little context around where I'm coming from ...

Quite level-headed; my congratulations.

What I will NOT do is tell my students that something else is inherently dangerous. I like to believe that people, given adequate information and training, are smart enough to figure out for themselves what are their best choices.

Nice to see that some things within the NAUI System...or at least some of their Instructors...haven't changed one bit.

To my concern, a well-maintained recreational regulator is not inherently unsafe ... as long as it's used in the conditions for which it was designed to be used (i.e. recreational diving). What can be unsafe is a lack of knowledge about the gear, a lack of practice at basic safety drills, and an unaware mind with respect to what's going on around you (especially with your buddy). Hog rigs are more efficient ... that's why I use one. But a well-educated diver can be just as safe and efficient in a standard rig, as long as they dive within their limits, know how to properly configure and use their gear, and practice safety drills regularly.

Exactly. FWIW, I really don't care for the contemporary business strategy to try to sell something through 'FEAR'. Doesn't matter if we're talking about scuba regulators, SUV's, or Household-based Electrical Generator systems.

But ... to address your last point ... regardless of what configuration they choose, no student of mine will dive with danglies ... that is a basic safety issue, and I won't compromise on those.

Agreed. A dangly-snag is a frequent enough risk which can precipitate a cascading failure such that a policy of prevention is the appropriate risk management strategy.

I think a comparison that would shed some light on this on-going tirade would be the percentage of deaths in recreational diving per annum compared to the number of deaths in technical diving per annum.

Would cave diving fatalities fall under tech or rec?

Tech.
Anything including overhead environment or greater than recreational NDL's. Even to include unqualified divers making tech dives.

If they had cave training they would be tech, if not they would fall under rec.

 

[The Kraken]

The dive itself is technical.
The comparison is between fatalities in the two sectors, not among divers.

How would contaminated gas fit in?and also poor heath ,and marine life? Would all these be contributing factors or should it just be tech divers verses rec divers

Tech vs Rec, period. End of statement.

It will take me a few days to compile the data if it can be done at all. I'll try and go back at least one year, and I'll post my findings in the accident forum

i,m really not sure what question this would answer. the per centages would be estimates and we would end up arguing about definitions.
