Buoyancy and Weight Estimator
This simple tool provides a basic starting point for recreational divers to estimate their weighting needs. Estimating your starting weight for a dive is part science and part personal experience. Everyone's buoyancy is a little different as is the specific gear brand and type you use. Which is why we give you a range, not a single number. You must always confirm your final weighting with an in-water check. For deeper dives on this subject, we recommend checking out our guides on Buoyancy & Weighting and Balanced Rigs.
Estimated Weight Needed
Freshwater: ___ pounds
Saltwater: ___ pounds
Always perform an actual weight check at the surface with a near-empty tank. Adjust for gear changes, undergarment differences, and personal buoyancy shifts over time.
