Ive been diving for many years with no trim or buoyancy issues. Recently i invested in a new bcd new new psotively buoyant fins. Things started to change. Ive now started cooler water diving and im face planting whilst underwater leading to an uncomfortable dive and a very sore back.m heres some info:
- female and short
- using a aqualong pearl bcd
- changed to negatively buoyant fins (this helped a little)
- 7mm wetsuit
- changed from 5mm to 3mm ankle booties (helped a little)
- moved all weights to weight belt and integrated pocket (not in trim pockets)also helped a little.
- tank sitting as low as possible in the bcd
- using steel tanks, 10L. Tried 12 but they are way too long for me.
- hate ankle weights, have strong currents i need to kick with ease.
Tropical diving, 5mm suit, al tanks im fine until the end of the dive when air gets lower. NEVER had this issue using rental bcd's. Even after all. The changes as above its just unbearable.
I had rhought it was the fins, im now thinking it might be the bcd and how it ends up positioning the tank.
Question: would a rear inflation bcd, help or make the trim worse? Im struggling to think of the physics involved here, and which way it will tip me if at all.
thanks so much!
