TDI training limitations...
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...
My NACD card calls out limitations,
My NACD Intro card clearly defines the allowable diving limitations based on the certification. The Doubles certification is noted, as is the "expiration" date which was 1 year from the date of certification.
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.
