I gave an example of a dive that I believe should have safety divers.
The moment that gear needs to be swapped/moved around is a disaster waiting to happen.
Thats why I feel that safety divers deep is a waste of a scarce resource. What really is going to happen? Just like the 120 stop. Take reg out of mouth....put reg in mouth. Kinda hard to really mess that one up.
For my example of the Athel Viking dives.
Diver removes leash with 50% and 100% bottles. (and holds that in one hand)
(This is neg by a couple of pounds, but the leash makes it easy to hold)
Diver then removes 80 stage and clips this to the leash.
(The 80 is pos and the 40's are neg, but the leash "system" is close to neutral, so if you drop it...it doesn't drop like a rock, taking your deco bottles with it.)
Diver then takes the 40's and clips them to his harness. (This is the dangerous part. This is where it is nice to have a support diver...to get back on topic
Now, If he drops the leash now...no biggie, those tanks are done.
Now, change all those luxfer tanks and make them steel bottles. It changes the dynamics of the whole swap.
Just like the 120 stop. Take reg out of mouth....put reg in mouth. Kinda hard to really mess that one up.
The bottle move is the dangerous part. A gas switch is always a danger, but your buddy is there. But your buddy can't replace your 50% bottle for you.Now, I'm confused- exactly what part of your Athel Viking example is a disaster waiting to happen? It sounds like a reasonable gas switch and bottle move to me. Or are you just saying the risk is higher during the bottle juggle?
Course, you might just put the wrong reg in your mouth...' you've then messed up '.
I might be looking for any signs of IBCD , but otherwise, there is lots of gas to deco on.
Always a slim possibility....we 'mix' divers should all be aware of the dynamics and signs of IBCD.
Having skilled support divers for 'typical' (I know...what ever that is) recreational tech diving is rare.....don't get to spoiled by all the attention.
