RAPID DIVER REPORTED BOTTOM TIMES...REPORT YOUR DIVE TIMES!

[Blub Blub]

I had been asked about bottom times when using the Rapid Diver. Here are some of my bottom times when I first used the Rapid Diver. They have remained in the same time frame since. I hope they will be of some interest and use to others. Bottom times with the Rapid Diver so far are not real accurate as it has been from 6 ft. to 37 ft. up and down depending on where I was searching. The first dive I ended with 400 psi after 42 minutes on air, and the second dive I stopped at 500 psi after 47 minutes on 32.7% nitrox. ( I can't tell any difference breathing nitrox over air, bottom times or any other I use it more as a safety measure while diving a air profile, and it is easier for me to fill nitrox. ) The first two dives were with a lot of movement doing searches and lots of fanning sand and silt. My third dive was in the same range but from 6-8 ft. for around 20 minutes then to 42 ft. for 10 minutes for a total time with 800 psi left, a total of 35 minutes on 32.3% nitrox. I have a 30 cu ft pony that I have had as much as a hour and quarter in 6 - 8 ft of water with 32% nitrox taking it easy. The fourth dive at depth of 36 ft. at a sunken boat. Bottom time: 31 minutes 30 seconds at depth to surface.another 10 minutes at 3 feet moving small rocks. Total time 41 minutes. PSI start 3500 end 750, with 32% Nitrox. The sixth dive at 36 feet for 31:30 minutes plus 10 minutes at 4 to 6 feet Temperature at the surface: 82°, bottom: 77°. Using 31.3% nitrox. This was a search on a 30° slope from 6 feet to 36 feet. back and forth over a distance of 100 ft. It was of 5 passes with over lapping vis, and fanning sand at the shallower depths of 4 to 8 feet. With the 30 cu ft tank at 3500 psi I cleaned a friends pool, on air, approximate 1½ hours with very little movement moving very slow about split the time from shallow end with deep end and stopped at 400 psi. Saturday on air and 3000 psi I made a lake dive to 36 feet for 5 minutes and then at 20± feet kicking hard for about 25 minutes, I ended the dive with 500 psi. I was done in then it was 30 minutes total time. I don't push it and am quite relaxed. I started diving in 1955 and have well over 12,000 dives. I would suspect the average will be around 25 to 30 minutes for most users, maybe less especially for rescue/recovery divers who are excited and practice much. From what I see the fire department and law enforcement and most people in this area don't do a lot of diving, maybe a couple dives one day a month in warm weather and on occasional trips, so their air conservation is fairly low.

Great post and one that everyone should read. You are right, the more you dive the better your air consumption will be. Even in stressful condtions, with the right training and conditioning you can still maintain a good breathing rate.

Just getting wet on a regular basis the key to keep you in top performance.

Great post!

Everyone should be monitoring their bottom times and logging them into their log books, I would like everyone on the Forum to list their bottom times to get a baseline. If you have a downloadable computer that would make the data more accurate. Are there any Forum users using a computer? If so what type?

I scored on some tank mountable shears/slate. The slate will work as a good place to put your data.

I use the wrist mount Aeris Atmos 2 and the Atmos AI on all dives.
I like redundancy.

23 minutes at 14' used 1800 psi. Using a Uwatec Galileo Sol wrist computer.

I average 40-45 minutes with the Rapid Diver Tactical version(30 cu ft. HP steel cylinder on my rig).
