Mandatory Dive Time per Dive ?

[sunfishh]

I use the 20 20 rule. If I "dive" atleast a max depth of 20 feet for 20 minutes than its an official dive. Of course you can use any standard you would like in your logbook.

I personally have logged only one dive of less than twenty minutes. It was cut short due to an emergency, that being why I logged it. Otherwise, I don't think I'd log a dive that short.

For example: During a shore dive, you and your buddy descend and swim to a known point of interest. At that first stop (let's say a swim thru) you can't find your buddy. You surface after one minute and both meet up on the surface. Since the depth was only 18 fsw and bottom time getting there was only 12 min, you both descend and finish the dive. The first 12 min wasn't a complete dive worth logging in my opinion UNLESS you log the whole thing as one dive. Just how I'd do it...not necessarily right or wrong. I might note the separation in comments, though.

Well, you can log anything you want.

Now I have never had a situation where I had a dive so short as to make me wonder about "logging it" as a dive. So I have never had that question. Most of my dives are boat dives with diving operators and they are 50 minute or 60 minute dives.

But there is a bit of a warning. Divers often consider the number of dives as a measure of experience. So I would not go out and do something to artificially inflate my numbers like doing 2 dives on a single fill.

But using dives as a measure of experience is not really that good either. A measure of experience is the conditions you have done your diving in.

I have one logged dive that was 1 1/2 minutes and another that was 3 minutes but that is because I learned something on both of them. (How many ways can you spell C.F.!!!) Generally I use a 20 minute limit -- however no depth limit because some of the best dives are in very shallow water that we normally swim over.

The PADI one is pretty good. I think an entry/exit dives would be required for me to count a single cylinder as multiple dives.

I can see that, but since I often dive a steel 120LP which the shop fills to 3000psi, and many of my dive sites are 25-30 feet, one tank can last... ummm... hours.

That's why I don't go for the "one tank means one dive" thing... I can dive all day on one tank.

If you surfaced, then you should be planning any further descents as separate dives in respect of tables/RDP. Likewise, dive computers will log further descents after a pre-set time on the surface.

If the dive was planned or recorded (dive computer) as a separate dive...then it makes sense to log it as such, regardless of entry/exit from water.

I wouldn't do it in most cases. I have on a few occasions gotten down to 30' or so with a buddy, surfaced due to some equipment malfunction swam to the boat picked something up and went back down (happened with a mask strap on my last dive trip about 1/4 through the dive). I have also been on a few dives where people have gotten separated from the group, surfaced, located the flag and went back down. All of these would be logged in my log book as single dives. Others can do what they want in their book, but I am not logging something separately unless it is a planned event such as a training session with multiple stages or I exit the water.

Most agencies have a rule similar to PADI's to prevent "tea bagging" to fulfill course requirements.

I can't imagine bouncing from and to the surface just to increase my dive numbers. Since my reason for diving is underwater exploration, and admiration, I'd never find pleasure in that type of activity.

I do agree that every in-water experience offers new knowledge, and no matter how long, or deep, a submersion is having a record in your log is a valuable reference.

thanks for the replies..

Don't get me wrong though.. I was not asking so I could start logging short dives just to get me count up. I'm fairly new, just got my AOW, and wasn't not sure of the rules.. if any at all.

The real reason asked is.. I recently had a dive time of slightly less than 20 mins. The dive wasn't planned this way.. we decided to cut the dive short due to viability conditions that we were not totally aware of. We knew viz was bad.. but 1-3 ft is terrible. So.. we surfaced..planned accordingly..then went back in.

Our next class will be Rescue Diver.. and the lake where we live will usually have bad viz. So.. gotta get used to it sometime.

I just didn't want to log anything that wasn't legit.

Thal.... I can assure you most strongly that THIS here PADI Instructor would NEVER allow "tea bagging" on his courses!!!!

Teabagging
`Teabagging` is a slang term for the act of a man placing his testicles, specifically the scrotum, in the mouth The practice vaguely resembles dipping a tea bag into a cup of tea
Found on Tea bag (sexual act) - Wikipedia, the free encyclopedia
