In fresh water you need
A
Less weight
4
Q
5 step buoyancy check
A
- Enter water in full gear
- Completely deflate your bcd
- Let yourself float vertically holding a normal breath - should be eye level
4 adjust as needed
5 sink slowly when you exhale
5
Q
If check with full cylinder
A
Add to kg
6
Q
Variables
A
1 suits -> suits gets compressed, less displacement, less buoyancy
2 gas consumption -
3 depth change - as you go down, add air to bcd to offset extra compression on suit
