Definition of Problem
Some divers appreciate having their valves checked, others hate it, and there have been DMs that have mistakenly closed the valve. Boat operators have liability and personal responsibility concerns and some divers have justifiable trust issues.
Proposed Improvement:
Since jumping overboard with a closed valve is only a small part of the actual problem, lets critique the following to see if it works for everyone and can be refined:
- Divers are requested to show their SPG to the DM and breathe from the regulator until the DM is satisfied that the cylinder valve is open AND the entire breathing system is functioning properly.
- I dont think anyone would object to the DM listening for leaks and looking for gear problems. If a concern is identified, the DM will always discuss them with the diver and never change anything without asking. Comment: It may slow the parade but IMHO beats the alternative.
- Testing the BC supply to verify operation may also be requested.
- Divers will be advised of this procedure on the pre-dive briefing so they can choose to postpone them before the witnessed test in order to save gas.
- Briefings should be concluded by asking for questions and special requests.
- SPG pressure can be recorded at the option of the DM and/or boat operator on leaving and returning as a backup to their everybody onboard roll call.
- Vindicator valve handwheels are desirable (not required), especially on cylinders provided by the boat.
Add to this list my own personal pet peeve: Cylinders supplied by the boat should be convertible between DIN and Yoke
but I kinda like the hot babes for DMs idea too.
Yeah yeah I know, men are such pigs.
