Diver one of sixteen to die using high-tech gear

[DiverMole]

OK, lets look at 50-70m dives on OC V Turtle

OC we are talking twin 12's and 232 bar. £35 ($50) for a fill of say 18/30. Also need side slung, say 7l of 50% min, probably 36% and 50%, or 28% and 100% depending on your preferances

My turtle rig for deeper dives has 2 x 7l cylinders, left is 18/30 right 100%. Costs me £10 ($15) for a fill which will last for 4 or 5 50M + dives
The 18/30 ius rigged in to my OC/DSV so I can bail to it istantly and I have a DV connected to the O2.

If I have a problem I bail (if I cant fix it staying on the loop) OC to the 7L of 18/30 (or 10/50) which is plenty to get me to 6m with my now extended stops (I carry an emergency bail out OC table as well as the VR3 being able to do this on the fly). At 6m I go to the O2 DV and can spend up to an hour on 100% (air breaks!!!)

The folks I dive with all tend to carry their own bailout so sharing isn't a problem, but all our dil cylinders (internal or side slung) are fitted with extra whips so we can cross plug our gasses into everyone elses units. I do not dive the unit solo

So lots of options, all safe, all redundant, no need to panic. And this is if you have to come off the loop in the first place (rare). This is why many RB divers believe they are actually safer at depth than the OC guys, we have more ways open to us of getting a breathable gas

If I want to go deeper I just add 7l Ali side slungs with say 10/50 and plug them in as needed

Hope that helps
