Question How old are you and how long certified? Poll- please take part!

[bradlw]

well I'm geting into this poll a couple years late... but luckily it's still the same age range now as it would have been back then so I'm not skweing the data.
59 YO, certified April 1994...so 31 years ago
I've had a huge 24-year gap in my diving so my dive count doesn't align with those 31 years...so I guess I've been only diving for 7 years

2 years late as well, no skewing here— what a perfect bell curve tho on the samples
1st dive 16y ago, 1st cert 8y ago

Changed my selection (vote) from 2 years ago - now 70. Only 19 dives since, but opted for Australia/New Zealand trip with no diving in 2024.

what a perfect bell curve

yes, and interesting that the average is clearly old-farts.
I guess younger folks are either too busy actually diving to kill time like this
...or maybe can't afford the sport!
.... or they can afford it but can't justify the expense.

so it leaves us old folks here trying to keep our heads in the game at least.

I haven't really looked at it closely, but these last few weeks as I've been trying to get my family outfitted for a certification class + trying to see what of my old equipment is still serviceable, it struck me that overall the sport seems like it might be more expensive now than it was back when I was active

The median and mode are 50-59, the weighted average appears close to 50. Drops off pretty steeply at >70.

I'm 71, in top 8.3%. Fortunately, my average RMV is 0.36 cu ft/min and I am in the bottom 12.8%, helps even it out . I've been certified for 55 years but had a very long layoff between 1980 and 1997. I'm just 12 dives short of 2,500 dives since 1997, will make it next trip.

Thread 'Average Gas Consumption'

Jul 3, 2016

There has been extensive discussion lately regarding average gas consumption. A poll may help give us a better idea of what the normal distribution of RMVs is.

1 cu ft = 28.32 liters
1 liter = 0.035 cu ft

<0.3 cu ft/min = <8.5 l/min
0.3-0.39 cu ft/min = 8.5-11.0 l/min
0.4-0.49 cu ft/min = 11.3-13.9 l/min
0.5-0.59 cu ft/min = 14.2-16.7 l/min
0.6-0.69 cu ft/min = 17.0-19.5 l/min
0.7-0.79 cu ft/min = 19.8-22.4 l/min
0.8-0.89 cu ft/min = 22.6-25.2 l/min
0.9-0.99 cu ft/min = 25.5-28.0 l/min
>1.0 cu ft/min = >28.3 l/min

49 years old. Did my first dive in ~2000 in Cancun, then OW pool dives in 2004. Didn't finally get certified until last July, 2024.
