Restriction definition?

[DaveP]

Is this still the correct definition:

"Restriction: A narrowing that is not large enough for two divers to swim through together (this is a minor restriction). A major restriction requires gear removal to negotiate."

Thanks,
Dave

A minor restriction is when your buddy is stuck.

A major restriction is when your stuck.

[Sludge]

Dave, your definition is correct.

[BgDadddy]

Hmmm...

So, by that definition, an intro diver shouldn't be able to go through the keyhole or that little area right before you get to the park bench...

[Sludge]

They don't have to be side-by-side. They could be one above the other. And nobody expects them to actually do it - it just has to be possible.

Rick, what did you think the definition was?

A minor restriction is when your buddy is stuck.

A major restriction is when your stuck.

I like this one better!!!!

Page 72 of the NACD Handbook-
Introduction to Cave Diver Limitations

Minor Restrictions Permitted - Minor restrictions - those areas of the cave which are too small to allow two divers to pass through at teh same time and require a single file formation- are permitted at the Intro Diver Level. Under no circumstance should the Intro Diver attempt entering any area compromising a major restriction - one which requires the diver to manipulate his body and/or equipment. Furthermore, there is no circumstance which justifies removal of life support equipment in the overhead environment

I'm guessing that a major restriction would be like cow entrance, not my fault, lips bypass, etc. Hopefully divers are well trained enough to evaluate their comfort level in order to make their own (educated) decisions, and don't have to get the standards handbook out to plan a dive.

A major restriction is when your stuck.

And a minor restriction quickly becomes a major restriction if it is blocking your exit.

Oh, I knew that was the definition, I was just talking smack.

I had forgotten about the "minor restrictions permitted" though in the NACD handbook that James posted. For some reason, I thought it said no restrictions and the keyhole was just something that was allowed to slide.

Although, if that was the case, people could always take the route around the keyhole on the right, which is wide open.

I beg to differ with that statement.
