This is usually said by someone who has very few cards....Cards don't mean squat.
Do you show your Rescue card?
Yes, but that was not the discussion. The discussion was which cards do you show.They look at your gear and they talk to you, and you tell them where you're from, your experience, and what kind of diving you do. That's worth a lot more than breaking out a stack of cards.
You say this a lot. It might even be true, but saying it a lot does not make it more true.There are many divers out there with every card available that still can't dive their way out of a wet paper bag. There are instructors out there that have done very few actual real dives outside of a training/class environment for their entire career.
DittoI have never had a divemaster talk to me and ask me about my experience and the kind of diving I do before a dive. They are usually pretty busy getting ready for the dive.
They can expect anything they want, but it is easy to say No or Pay Me.I see comments about "show the minimum needed".
Wrong, show as much as possible, but not to the point they will expect you to work for them. Show that you have experience, know what you are doing.
