That "just follow the bubbles" tip from a retired diver in Port Fourchon actually worked
Old timer told me to trust my lifeline tension instead of the visor gauge during a low-vis pipeline job, and after 2 hours of zero issues I finally get why he was laughing at my trim weights, anyone else had a mentor's random advice click way later on a different site?
Wish I'd had someone like that when I was learning. My first few months doing low-vis work I was glued to my gauge like it was the only thing keeping me alive, and my old super finally grabbed my shoulder and said stop looking at the numbers, feel the line. Took me forever to trust it because every bone in my body wanted that dial confirming things. Just like your guy laughing at your trim weights, he was probably watching you fight gear that was set up wrong the whole time. Had a similar moment on a dock job years back where a guy told me to count my breaths instead of watching my pressure, and it did not click until way later on a totally different site. That kind of advice sticks because you have to earn it yourself, you know? Glad the bubbles and the tension both came through for you down there.
