yeah gerald thats what happened to me- in the quarry though during my OW cert. i somehow got it under control though- dont really know how though.
reading all these LDS (which i assume stands for local dive shop) horror stories, my heart really goes out. the guys at my Local Dive shop were very nice and happy to help with anything i needed. they required us to buy fins, a mask, a snorkel, and a reg mouthpiece for our OW cert class. Trying to save some money, i called up my Grandfather who is an avvid scuba diver down in Miami to send me up some fins and a mask to save some money. somehow, it wasnt there on the eve of my first pool class! i was freaking out, beacuse how was i supposed to go to my first pool class without any equipment. in an act of desperation, i called the LDS taht runs the class and the owner was very sorry for me. i asked him if he rents any of the above stuff, and he apologized and said no. NOt beacuse of bussieness issues, but simply because many people like to buy this stuff on their own or rent from the dive shop they are going to on vacation. he then said if i wanted, he could close the shop and run home to get some of his stuff for me to use until my gear came. that was a very nice gesture, but i ended up suckign it up getting my own equipment which now i really adore and glad i got it (i LOVE my stuff.) when i was reading all these LDS horror stories, i got very confused. hearing all of these, i think i am going to stick with my LDS for a looong looong time.
