Hey jim---given its a male instructor and female pupil I reckon if he was to be playing around with her chest region he might end up in a power of hurt. -just a thoughtThe other is to grab the front neck of the wet suit to bleed any trapped air also the back of the BC can trap air....

Matey sound like you and i followed a similar path -different locations but similar eclectic mix of dive conditions.No offense taken. I log every dive and by now I am getting it down quite well. But I travel and dive by myself so you realize that I often get to a place, get on a boat with other divers, buddy up, guess the proper weight given the water temp, exposure suit etc and get in the water. In my experience with now a number of dive shops, they really don't want take time to weight check everything.
I'll give you a 3 month example.
1, Cuba, salt 85 degrees 3mm shorty, steel 80
2. Italy. salt 60 degrees 5mm full, Steel 100
3. Alberta fresh full 7mm booties hood and extra vest 14mm on core 45 degrees, Al80
4. San Diego straight 7mm, Al 80, 55 degrees
As I said, I log every dive and now am getting pretty good after about 35 or 40 dives but when the shops push you through, what I log in my book is the gear, the weight and comments like a little overweighted, little under" and adjust for the next time.
Another thing you said was "That gives you a baseline for the next dive in the same conditions." Being slightly "ha ha" older than 10, I do refer to my log and equip properly if I have dove in the same conditions before.
I know... I should demand to do a weight check but there is peer pressure when you got 6 or 7 in the water wanting to go down, especially when you are the junior diver. BTW, have I said I believe I got it by now. Still learning other stuff though. Thanks.
Hey and the cool thing about diving is you NEVER stop learning something new.
