Buoyancy and weighting: how much weight do you really need?
Properly weighted, you should float at eye level with a normal breath in and an empty BCD, says PADI. Carrying too much lead makes you swim at an angle, work harder and use more air. Do a weight check, descend calmly and level out horizontally, and write your weight, suit and tank in your logbook so you can start right next time.

How do I check my weighting?
At the surface, with an empty BCD and a normal lungful of air, you should float at eye level, hanging still without kicking or sculling. When you breathe out fully you should start to sink slowly. If you sink like a stone, remove some weight.
How should I descend?
Stay still and vertical, breathe out fully, then take small breaths in and long breaths out. As you start to sink, use your core to bring your body face-down and horizontal, and add a little air to your BCD before you reach the bottom so you don't touch it.
Why log my weight?
PADI suggests recording the weight you used on each dive, whether it was salt or fresh water, your tank type and size, and your wetsuit — so you can estimate the right weight next time.
Frequently asked questions
Why does overweighting matter?
It pulls your hips down, increases drag and makes you work harder — all of which use more air.
Is there a course for this?
Yes — the Peak Performance Buoyancy specialty focuses on it.
