They call them trim nazis.
Assume the DIR position soldier!
The all touted perfect skydiver position, not exactly the most streamlined thing I’ve ever seen. Look closely from the side at somebody who swears they are in the DIR “perfect trim” position. What do you see?
I see the tank laying at an angle pointing uphill catching water (worse with a STA), I see their crossed hands in front and below their straight line catching water, I see their goofy feet sticking up catching water. From the side they look like a blob. From the front they are not exactly punching the smallest hole through the water. They are anything but perfectly flat!
That position is great for slowly moving through caves, wrecks, and for hovering above a silty bottom without disturbing it, agreed.
But there are a lot more circumstances in diving and the sky diver position isn’t always the end-all answer touted by the self appointed dive gods in all scenarios.
Fortunately, the trim nazis seems to be a scubaboard thing, at least from what I have experienced. We had one here but he moved away.
Wow! I’m so glad they don’t write the scuba laws.
