so, I have a question, if everyone is ascending, and you have 2000 psi left, have you ever just sort of nonchalantly pretended not to notice and keep diving...? Sometimes it is better just not to look.
I smiled when I read that.
A lot depends upon the dive plan, what you agreed to by sitting thrui the dive briefing and not raising your hand when the DM asked, "Any questions?"
I have seen some interesting solutions to this problem. It does depend upon the character of the dive.
If there are two DM's, one will continue to collect the heavy breathers and eventually herd the upstairs en masse. Obviously, this is dependent upon everyone using the "1/2 Full" (referee's Time out hand sign) when they have reached the 1500. The assigned DM can then begin to assess everybody's rate, and he will understand that the first diver to signal will use exponentially more and more air as his worry factor sets in. Eventually, he will gather his charges and slowly ascend. In some places with different theories on liability, the DM will hand the air sucker a long hosed 1st stage as we all cling to the lava formations watching for the Hammerheads to fly by in the underwater breeze.
In a gentler situation, say the Caribbean, it depends upon whether its a moored dive or a drift dive.
In a
drift dive, the DM usually handles the reel and the dive flag. The Boat Captain, very much so a real part of the dive team, follows this and his trained eye can spot individual divers by their bubbles. If select divers are directed skyward, they should understand to make a slow ascent, keeping forward pace with the dive flag- after making a moving 15' safety stop (a real skill to be learned), they ascend and signal the driver by whatever agreed upon method.
This is where the skill of deploying the sausage from depth (20fsw) on a line and then waiting 5 mins at 15fsw, all the time staying near the flag. Many do not understand how very little air they consume at 15fsw and really begin to panic, causing heavier breathing. At 300 psi one might hang at 15 feet for 15 minutes
if in good form.
On a
moored dive where the DM is signalling the 1/2 way point in a wall dive, where he wants you to slowly ascend then at a predetermined shallower depth, begin your return to the mooring pin. If I were the DM, if you showed me your gauge with 2000 psi, signalled me that you were going to go a bit further and then loop back, I would then give you the OK and dawdle back with my ducklings.
If, however, I was a Cayman divemaster, I would hold your hand, tell you "no-no" and then lead you back to the boat. I would do whatver my boss told me to do.
In the Philippines, the resort told them 30 min BT on night dives. After day three we had a chat with the DM and told him that we weren't going to say anything if he wasn't. We would drift along in 20' in ripping currents for 1:30, until he got cold and got out. 15 minutes later we would follow.
It all depends on who you are (both parties) and what the DM is directed to do. Pick your dive ops wisely.
