A few points some of which are YBOD specific.


1: There is no such thing as a bimble CCR dive

2: 02 cells are far from perfect and can fail from new, never fully trust them

3: On a two day dive dive 1 and dive two are totally separate events and pre dive checks should be just as meticulous.

4: Assembly of the unit should follow a totally strict list of events and checks. If you mis cock up or feel unhappy about any stage of preparation my advice is take the whole thing apart and start again.

Assembly of the unit is best achieved by laying out all the components in task specific order prior to starting.

5: Sofnalime is damaged by frost and should be stored in an area comfortably above zero c and propped up on insulating wooden blocks.

6: Flapper valves are probably one of the least checked / inspected items on the CCR and yet one of the most likely to kill you.

7: Bailout gas is for people who need to stay alive. Alpinist is for people who don't care if they do or not.

8: Small bailout cylinders are carried by people who pretend they want to stay alive.

9: Bailing out to Air can and probably will kill you at depth

10: If you breathing a little hard and cant think of a reason why BAIL OUT IMMEDIATELY as in a few moments time you wont be able to.

11: BOV's and Full face masks are a major contribution to CCR safety

12: HUDS are critical safety equipment and should be fitted to EVERY ccr. Diving without one leaves you blind to whats going on for 75 - 80% of the dive or ruins the dive because all you see is 1.3 1.3 .13

13: Electronics and salt water are sworn enemies. Dead divers are collateral damage in their epic struggle
