Well i am going to get into the process of "collecting cards" over the years, not for the sake of it, but to gain knowledge of an new skill/type of diving and then try to get out and use that new info to dive better. I am not going to try to get the very tough fish ID type ones, but i might like to do a cavern after AOW, rescue and a few others - cos i think i will want to dive in many types of environments that i dont currently do. Do i think it is a "license", of course not, but it gives me a chance of being intoduced to a new sphere of diving that i might kill myself doing IF i didnt get the training.
Will the cards say anything about my diving, watch me in the water and see how i dive, make your own conclusions. I want to learn more, to experience the wide variety of different environments that diving can offer and move more seriously into some of them, so i think the training is very useful - the card at the end is just a reminder that i passed a few tests of what i was taught along the way.
