Estimate the amount of lead weight needed for proper buoyancy while diving.
Diver Profile
Safety Note
This is an estimate. Always perform a buoyancy check at the surface before every dive.
Weight Estimate
Enter your profile to calculate estimated lead weight.
Overview
Your requirements depend on body mass (approx 10% for salt water), exposure suit thickness (adds positive buoyancy), and tank characteristics. Steel tanks are typically negative, while aluminum tanks become positive as they empty.

Fun Facts
"Proper weighting allows you to maintain neutral buoyancy with a near-empty BCD at your safety stop."
"Fresh water is less dense than salt water, requiring approximately 2-3kg (4-6lbs) less weight."
"As you descend, your wetsuit compresses, losing buoyancy, which is why we add air to the BCD to compensate."
