50-59. Looks like we quinquagenarians form a plurality, at nearly 24%.
Certified 25 years ago. But I guess I don't really dive much. After 25 years I have only ~300 logged dives. I guess I don't like the cold, black water, and that's all we have around here. 45°F or so even in the summer, with maybe 3 feet visibility. I have a dry suit and a backplate rig and doughnut, but I only rarely make those dives. Sometimes with Gypsy Blood Divers on the Jersey coast, and sometimes in the rivers and quarries in eastern PA. Mostly I prefer the tropics, and that's a long and expensive trip so I only dive 15 or so cylinders per year. But I love diving. For many years before I was certified I'd take a mask and fins and go down to 20 feet or more searching for treasure, or just to observe.
Deepest dive: 340 feet.
Shallowest dive: 11 feet.
Longest dive: 3 hours 15 minutes.
Number of times I shat in my wetsuit: 1 (horrible experience)
Number of times I had to abandon a sinking diveboat: 1 (also a horrible experience)
Number of times I completely exhausted my breathing mixture and had to reach for another diver's secondary: 1 (Best. Dive. Ever. Lightening storm above and the DM said we had to stay down no matter what. Saw a pod of 7 black dolphins swim within a few feet of me. Described it as a "school of dolphins" but there was a marine biologist on that dive and she promptly corrected me. Fish come in schools; dolphins are mammals: they come in "pods". Fair enough.)
