Have you gotten bent?

[sskasser]

According to Delta P the depth sensor went bad, I didn;t turn it on prior to jumping in and it didn't kick in for like 30 min. I normally wouldn't check the computer on a wreck like this because I know how deep I am. Anyway I still have the computer as a backup(witha new sensor) and I dive a Shearwater connected to my Inspo. as a main.

It's a good heads-up to us all to check all gadgets after entering the water. Thanks!

Those VR3's do weird things. Mine reset TWICE while on deco a few years ago, on different dives. Luckily I always wore 2. One minute you have an hour of deco ahead of you, the next you're clean and ready to exit... pretty disconcerting...

Agreed, very disconcerting. Any explanation from Delta-P? By 2, do you mean 2 VR3's? Only one of them do the reset thing?

Yep, I had 2 of them and only 1 would keep resetting. delta P thought it was probably a bad connection to the battery - that was always a weak point on those units, the battery housing is very fussy about the shape of the battery's negative terminal. Funny how toy manufacturers can get it right, but $2000 computer manufacturers can't ... sorry, I'm venting here!

LOL, and preaching to the choir

LOL yep thats what they told me as well. I gotta say once I save up enough cash I'm gonna replace the VR3 with another Pursuit. IMHO a far superior product. I don't care its not in color and I can't play games.

Mine did that too......of course I had tables to bail out on, after that.... got rid of it. X1 is FINE!

Actually it was erroneous information, it neglected to count about 28 min of the dive. So in reality I thought I was down for about 30 min or so when in reallity it was closer to an hour. My fault for not paying attention to how long I was down.

Interesting. So far, HALF the respondents have had some sort of incident. And I didn't even impose a limit on minimum nomber of cave dives.

Seems like "bent cave diver" is almost tautological.

I doubt that the category mild type 1 (untreated) would qualify as getting bent in a scientific survey. eliminate those as not really bent and the numbers show a whole different thing.

also, the bent cave divers are 1) those who attend to this forum and 2) those who have been bent or think maybe they have are the ones most likely to respond to the poll.

These polls are fun little topics for a discussion, but have no relationship whatsoever to reality.

I think you're seriously wrong about your first statement. I just know too many people who are reasonably tough individuals who felt serious pain, but didn't get it treated. You're suggesting that a lot of them are hypochondriacs. I can't guarantee that they aren't, but I'll bet you have one of more diving buddies who took one or more fair hits and never went into the chamber.

Your next paragraph - 1) well, duh! - that's the whole point, it's THIS GROUP that I was interested in, and 2) based on what evidence?

This poll ain't perfect but it's a lot more indicative than you're claiming. Some percentage of that "type 1 untreated" group may not have actually had a hit, but let's say that somewhere between all and 1/2 actually did (and I'll bet it's way closer to the former)). That would still leave you with roughly:

60-72.5% no hit
12.5 to 25 % mild untreated
8.8% mild treated
5.8% serious treated

That's still a VERY large percentage. Still it makes sense really. Getting bent is a stochastic process. Computers and tables don't guarantee never getting hit, they aim for an acceptably low rate. Let's say that rate is 0.1% per dive (I'm guessing but I'll bet it's of that order). That's one so-called "undeserved" hit in 1000. And I'll bet that the average number of dives for people on this board is at or above 1000.

Plus - aren't you amazed that about 16% have taken rides?

Dive enough, and your chances of taking a hit start looking pretty large. Especially when a large percentage of those are deco dives, which by definition are "pushing" the tables.
