Weight for a drysuit: what to know
The air layer in a drysuit and the thickness of your undergarment change your buoyancy a lot. Weight yourself with the undergarment you will actually dive, and get drysuit training before diving one.
Worked example
For an 80 kg diver with an average build, wearing a drysuit and using an aluminum 80 tank in saltwater, the calculator estimates 10.5 kg (23 lb). Your number will differ with your body and gear, so enter your own values above and then do a buoyancy check.
Common questions
How much weight for a drysuit?
Commonly 6 to 12 kg depending on undergarment and body size. This model estimates about 8 kg for a base setup.
Should I use the same lead for every drysuit dive?
No. Re-check when the undergarment or tank changes.
Do I need training to dive a drysuit?
Yes. A drysuit changes how you control buoyancy, so take a drysuit course from a certified instructor.
Why does a drysuit need so much weight?
Air in the suit and undergarment adds lift, and thicker undergarments add more.
How should I weigh myself for a drysuit?
Dress exactly as you will dive, with the undergarment, and check with excess air released from the suit.
