Wow, you come off sounding incredibly belligerent. Did I personally offend you somehow?
Yes, I personally know and have dived with people who have had problems with both fills and with getting onto resort dives with tech cards, or have witnessed firsthand. Many have posted about it firsthand, too. Let me help you out:
http://www.scubaboard.com/forums/4069963-post7.html - Tech 1 card refused because it wasn't AOW
http://www.scubaboard.com/forums/4070256-post19.html - NAUI instructor card refused
http://www.scubaboard.com/forums/4070435-post25.html - Danny Riordan's Cave 3 instructor card refused because it didn't say NITROX on it.
There are others, too. These are all from a single thread, a search will undoubtedly uncover more. Soo...at least we're not "Kinda curious.
" anymore, I hope?
One good suggestion I found when perusing these old threads is to take a picture of your c-cards and keep them on your camera. It may or may not help, but it's a bit of no-cost insurance that might save your dive if you leave your cards behind.
