Why does nobody talk about how different bottom times are between quarry work and open ocean?
I spent 6 years doing inspection dives in quarries around the Great Lakes region, where visibility is usually 10 feet or less and you're working in a controlled environment. Last spring I took a job on a pier repair project in the open ocean off the coast of New Jersey, and the difference in bottom time was striking. In the quarry, I could push 4-5 hours easy on a light day, but out in the ocean with current and surge, I was gassed after 2 hours even with the same gear. Has anyone else noticed this split between inland and offshore work, or is it just me getting old?
