Mine was in the late 60's in a NE Pennsylvania lake. Small shop rented ski boats and dive gear. Mom took me for my 12th bday. Guy asked if I could swim (yes), strapped a steel 50 to me with a J valve and dual hose regulator. Said try not to go over your head, don't hold your breath and come back when it gets hard to breathe. No BCD, no gauges, remember that dive to this day. Years later got certified in Norfolk, Va. Became an instructor with SSI and PADI with several specialties. Remember that first dive to this day. Couldn't afford a Doxa then, can now. These days I find things that folks drop off the dock and clean my boat hull. You?
