1. What is the PADI Weight Formula?

The PADI weight formula helps divers estimate how much weight they need to achieve proper buoyancy. Proper weighting is essential for safety, comfort, and air consumption during dives.

2. How Does the Calculator Work?

The calculator uses the PADI weight formula:

\[ Weight = (Body\ Weight \times 0.1) + (Tank\ Factor) + (Exposure\ Protection\ Adjustment) \]

Where:

Body Weight — Your total body weight in pounds
Tank Factor — Adjustment based on tank type (Aluminum 80 adds 2 lbs, Steel 100 subtracts 4 lbs)
Exposure Protection — Adjustment based on wetsuit thickness or drysuit (+2 to +6 lbs)

Explanation: The formula accounts for your body's natural buoyancy, the buoyancy characteristics of your tank, and the additional buoyancy from your exposure protection.

3. Importance of Proper Weighting

Details: Proper weighting is crucial for safety and enjoyment while diving. Being overweighted makes you work harder and consume more air, while being underweighted makes it difficult to maintain proper buoyancy.

4. Using the Calculator

Tips: Enter your body weight in pounds, select your tank type and exposure protection. The calculator provides a starting point - always do a buoyancy check in the water with your actual gear.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculator suitable for saltwater and freshwater?
A: This calculator provides values for saltwater diving. For freshwater, you'll typically need about 2-4 lbs less weight.

Q2: Why does tank type affect weighting?
A: Different tanks have different buoyancy characteristics. Aluminum tanks become more buoyant as you breathe them down, while steel tanks remain more consistent.

Q3: Should I always use this exact weight?
A: This is a starting point. Factors like body composition, gear configuration, and personal comfort will affect your actual needs.

Q4: How does exposure protection affect weighting?
A: Thicker wetsuits and drysuits trap more air, making you more buoyant and requiring additional weight to compensate.

Q5: When should I re-evaluate my weight needs?
A: Whenever you change equipment, exposure protection, or if your body weight changes significantly.
