Buddy trained at intro level.... received NSSCDS Basic and TDI Intro cards...
TDI card specifies following limitations: Max depth 130' w/ 30' vis, no deco, no restrictions, reserve 2/3 air supply to exit, continuous guideline to exit, at least 3 lights/diver...
Is single tanks assumed....?
Card makes no reference to advanced topics; navigation jumps, gaps, curcuits, traverses
TDI's site is lacking on detail....
Whats the scoop...?
-------------------------------
Yes - they are diving 6ths...
1/3rds in based on singles, supposed to follow 1/6s on doubles. You will not be allowed in Ginnie if you tell them you are diving doubles. It restricts you to mainline, no jumps, gaps, etc.
Was he trained in doubles or singles? If he was trained in doubles, he needs to get a letter from his instructor stating this and present it to the folks at Ginnie. They should allow him to dive Devil's in doubles with the letter. And as Ant said, in doubles, penetration is limited to 1/6.
My IANTD intro cave card states specifically "introductory cave with doubles."Will I have a problem at Ginnie if I want to dive doubles? I also have TDI advanced nitrox and deco procedures cert cards and never dive anything but doubles anymore.

It's all my curiosity at the ambiguity in the cards text... as the card was issued under reciprocity... Nothing more...Quote:

It is 1/3 in single and 1/6 in doubles
It is a Single primary guideline
Yes it does say about advanced topics! - Introductory Cave!
There is nowhere in any sport or profession you would learn advanced topics in an into class.
I am not an Instructor for NSS-CDS but I believe that the change from Into to Basic was to identify the new standard for Doubles. So I don’t believe you need a waiver there either.
As far as I know IANTD is the only one now that you would need a waiver for doubles in Intro.
No waiver needed for IANTD. They print "In Doubles" on the card, but the instructor needs to let Patti know this on the application. I don't know if TDI does this or not, but I do have a couple of friends that were almost not allowed to dive Devil's because they didn't have anything that said single or doubles on their cards or in the form of a waiver.
TDI cards do not distinguish between being trained in doubles or singles.
Hey Tim,
Good weekend?
sounds like your buddy needs a nice NAUI Cave 1 card :).

Ginnie has had no problem with this card. The Intro (w/Doubles) card is pretty much a hand made affair with the written info typed on white card stock and then laminated in plastic.
I had the same thoughts netmage when i saw the card before and was wondering the same thing but after going back to ireland had no way to find out then totally forgot about it over time to send e-mail ask i like seeing the answers to your questions helps me understand as welll a bit.
The NACD card sounds like an Apprentice card not an Intro card.Quote:
