I finally quit arguing with a tender on a piling job in Galveston and his one line stuck with me
We were doing a 40 foot inspection dive on some old timber piles down near the wharf, water was murky enough I was basically working by feel. I came up hot about something small, I think it was the umbilical getting pinched on the rack, and I started going off at the guy running my line. He waited till I was done, then said real calm, "You watch my back up here, I watch your air, that's the whole deal." Never raised his voice, didn't argue the point at all. I've been on maybe 60 or 70 jobs since and I still think about that. Now I try to sort out the line feed stuff before we splash instead of after. What's the one thing a tender said to you that actually changed how you run a dive?
