Hours v Dives

buggeriamold · 25th July 2005, 02:06

It seems to me that oc divers seem to talk of experiance in dives, cc divers in hours. Any theories on why this is?

Probably because we measure and record all kinds of time, like scrubber and battery usage.

Many Rebreather dives involve deco and and therefor require real dive planning, again measuring runtime, stop times, O2 exposure time, RMV for bailout etc. Even during training times rather than dives are required.

On OC it starts with number of dives for OW certifications and pretty much stays that way, certainly on the recreational end.

Besides, that way the numbers are more impressive:
For OC 100 dives sounds much better than 65 hours, and on a CCR 100 hrs has a different ring than 65 dives.

Hell, just giving hours instead of dives irritates the OC crowd.

True, but I got a piece of advice from Andy Driver when I was shopping for a KISS instructor. He said that ascending and descending are the most important parts of learning on a Rebreather (I assume he meant since they are the times PO2 is most dynamic and buoyancy control most important).

I think this is probably why the IANTD Mod 1 standard is written for dives and minutes.

I think.

On a recent trip to a local wreck (top 16m, bottom 41m) the OC guys on board were chuffed they did four 45min dives on the wreck over the weekend.

I only managed half the number of dives as them - only did two dives. The first dive however was 3.5 hours on the wreck, the second 3 hours

All bottom time no deco.

I guess the difference is it doesnt matter how many dives you actually do, its the amount of time you spend diving that counts.

You're correct, Dan, there are minimum requirements for both the number and and the time.

They count the time whereas men count the times.

overall a measure in time would be a better indication. in the marine world and especially in aerospace, pilots and many more personell are required to keep a log. thay all count the sailing/flying in hours.

ideally the oc sport diving community should transfer to in logging divetimes rather then actual dives.

best for all i would think would be a 2 number system of dives/hours.

Up to 100 dives OC I got excited and when I switched to CCR I was desperatly trying to get to 100 hours but now i have done the probationary period and got the mix ticket I wanted so badley I dont give a dam what hours or how many dives I have. I do as many as my wife my family and my job will allow and the wether will permit.

All I know is if i were single and lived in a diferent country it would be a damed site more
