How much weight do I need?.
Refer to your certifying agency procedures to plan your dives.
This weight calculator is based on the PADI Weighting Guidelines used in the Peak Performance Buoyancy course.
Although only a buoyancy check can determine the proper amount of weight needed, here is a weight calculator that'll get you started.
This calculator is based on individuals of average build, diving in salt water. Lean individuals may need less weight, while heavy individuals may need more.
You may also need to add more (or less) weight depending on any of the following:
- additional dive gear you carry (cameras, reels, lights, etc)
- type and size of tank (you will need more weight for aluminum tanks)
