Final Decompression Stop Depth

Lancer4545

Seeing as you're in the mood for polls, here's another one for you.

If you'd like to make a SHORT explanation why you stop at a particular depth please do so.

Regards,

Lance

6m for me usually:

• easy to hold
• less effected by surface swell
• away from keels of any boats
• Can stay on ppO2 of 1.3 without hassle

Sometimes come up to 4.5m - esp if on O/C - if its calm.

Same as Steve and from 6m and up 1m/min. If long deco.

6m for me as well with slow final ascent. All the above reasons.

Last stop at 3m, for me depend on surface, and finishing with at least for 3 to 5 minutes on the loop with a O2 flush again on surface.

Usually 6mtr myself, same reasons as above....

When I did my OC Trimix cert I was taught something the instructor called "sloppy 6's" (it had another name I can't remember) which I've always rather liked.

The idea was you cut two plans and compare the last stops, with a last stop at 6 it might be 20minutes, last stop at 3mtrs might mean 8min at 6mtr followed by 10min at 3mtr (for example)

When you execute the plan you come up and do the 8min at 6mtr planned stop then you do a very gradual drift up to 3mtrs over 10minutes until you reach 3mtrs and the length of the longest plan (which was 20 at 6) and then 3-4minutes minimum to the suface... (remember this was a gas course afterall) The thinking being that the difference between the two plans could be done anywhere between 6 and 3 and you could approach the surface slowly and in control. rather than jumping from 6 to 3 and loosing it.

This was before VR£ diver on a rope, GF and other intermediate stops where common knowledge, although Pyle Stops where making an appearance, so I used to do Pyle type deco up to 9mtrs then this Sloppy 6 stop took me the rest of the way.

I now use the Shearwater GF but on big dives I still use to "drift" stop last, when the computer clears to 3mtrs I start a slow ascent over whatever stop time it suggests, maybe it takes abit longer but it feels good- I'm not one who's ever understood the rush to surface but maybe my divings just not deep enough?

For me 6 meter too. Same reason. If possible I make a very slow ascent to surface (1 M/min).

Hi,

I have just bought a HH controller and the last stop is at 3m. I personally would prefer to do the last stop at 6m but it's not an option on the computer.
What do you do guys when you're following the deco on you computer? Do you still do the last stop deeper than what the computer says? Doesn't it take ages to clear the last stop?

VR3 lets me select the depth of my final stop... but with the diver on the line tool it also lets me go above this depth if I want when it shows its actually safe to do so.

I use Vision on the other wrist and this shows me my current ceiling which lets me do the same.

10 feet unless on O2 or if surface condition make the stop to hard to keep.
