To original OP: Its purely a marketing gimmick. Think about it: Do you consider yourself a master even if they give you the card.
I am humbled frequently diving after I realize I should have done x while I did y. Enjoy the diving without all the labels.
I appreciate the encouragement. I do understand the marketing part. I was only trying to bring some levity (myself being humbled) and poke some fun at the use of "master" titles a bit too loosely. I suspect that it will be some time before I would begin to consider myself as getting close to a scuba mastery of any kind. Unless losing stuff becomes a specialty. Well, not to humble brag, but I am pretty good at diving with a tiny bit of water in my mask to wipe any fog that creeps up.
I am enjoying my progress. Enjoying the learning and growth. My scuba life is pretty good.
