That comment about intro on doubles having a worse safety record than intro on singles is crap at best. It all depends who is tracking these records and what parameters are used....... did they die, have a near miss, ran out of gas, got lost and gas saved them etc, etc. No one is tracking that to the best of my knowledge, so let's not pretend we know.

My understanding is that no intro diver has ever died on a dual-outlet single tank, despite all the hand wringing over burst disk and neck o-ring failures whenever this debate comes up. All the accident analysis articles I have read involving intro divers were situations where intro divers, in doubles, were performing a full cave level dive.

I still do not see why double tanks are needed for an intro level dive. It is like packing up provisions for a week-long expedition on the Appalachian trail and then going for an overnight hike at O'leno. If someone is so concerned that they are going to get lost and need that extra 5 days of supplies, maybe their first concern should be improving their experience and navigational ability rather than bringing extra equipment to compensate for both. Diving a single tank forces an intro diver to dive conservatively and slowly build experience, which in my opinion is best.

Boy Scouts Found in North Carolina Mountains
Monday, September 24, 2007


WAYNESVILLE, N.C. — Eight Boy Scouts who got lost while camping in the North Carolina mountains turned up Monday as searchers scoured the heavily wooded area, officials said.

"They're fine," said Donna Johnston of the Boy Scouts' Occoneechee Council in Raleigh. "They're out of the woods."

Johnston said the boys and their three leaders had gotten off a trail and decided to set up camp for another night. They waited until daylight rather than trying to walk out in the dark.

Rodney Jones, an assistant Scout master whose son was in the group, said they followed their training.

"I knew they would do as they were supposed to do and that is hunker down," Jones said. "Everybody's in good shape, a little tired. They said if they had cell service, they would have called us. They were, as the Scout motto says, they were prepared."

Kathryn Logan, whose brother was among the lost Scouts, said he was finally able to get cell phone service Monday morning and told her the troop had gotten off the trail.

The group started the trip Friday and was due home Sunday evening. The search was started after they failed to return as a precaution in case any of the boys, all age 12 or older, might be injured, said Charity Sharp, spokeswoman for the Cruso Fire Department.

Firefighters and search and rescue crew members checked a five-square-mile area near Black Balsam Knob in southern Haywood County overnight, and a fresh search team of 15 to 30 people with tracking dogs went out after dawn on Monday, Sharp said.

Is that a function of the doubles or the mentality/maturity of the diver?
 
Do you think a sports car is the best choice for a 16 year old's first car?

Do I? No. But take a look in the parking lot of a nearby high school and tell me what you see. Bad choices abound.

One could also argue that pursuing cave training before a solid foundation is built in open water is inherently dangerous. Doesn't stop people from doing that either. Same with decompression diving, rebreathers, or any other more technical diving.

It could likely be argued that intro divers in doubles having a higher accident or incident rate falls more to the personality of the diver than the equipment. Just as we could say that the teenager who begs for the hot sports car instead of the Camry is exhibiting certain personality traits.
 
I say 16 year olds should drive DOUBLE MUSTANGS! :)
 
I wish ScubaBoard had that "beating the dead horse" emoticon that DecoStop has.
