Achieving perfect buoyancy control is a skill that every diver aspires to master. One of the crucial components of this skill is proper weighting. Whether you’re a novice diver or a seasoned pro, finding the right balance of weight is essential for a safe and enjoyable underwater experience. In this article, we’ll delve into the importance of proper weighting when diving, the science behind it, and practical tips to help you dial in your ideal weight.
Why is Proper Weighting Important?
Proper weighting is not just about comfort; it’s the foundation of good buoyancy control. Here’s why it matters:
- Smooth Descents and Ascents: The correct weight helps you descend and ascend smoothly, without any sudden drops or ascents.
- Comfort during Safety Stops: Proper weighting allows you to comfortably hold position during safety stops, crucial for decompression and safety.
- Improved Gas Consumption: Carrying less weight means less drag, resulting in lower gas consumption (SAC rate).
- Better Trim and Maneuverability: As your buoyancy improves, you’ll achieve better trim in the water, allowing for smoother finning and maneuvering.
The Science Behind Correct Weighting
Understanding the science behind proper weighting involves Archimedes’ Principle:
- Archimedes stated that “An object placed in a liquid will be buoyed up by a force equal to the weight of the liquid it displaces.”
- This principle applies to divers and their equipment. For instance, a slim diver in a thin wetsuit requires less weight than a larger diver in a bulky drysuit.
- The weight/volume ratio is crucial. For example, adding more equipment like twin tanks increases weight but also volume, affecting the required weight.
Where to Start: Basic Guidelines
If you’re unsure where to start with your weight, here are some basic guidelines based on your exposure suit:
- Swimsuit or dive skin: 1-4 pounds (1 to 2 kg)
- 3mm wetsuits: 5 percent of your body weight
- 5mm wetsuits: 10 percent of your body weight
- 7mm wetsuits: 10 percent of your body weight plus 3 to 5 pounds (1 to 3 kg)
- Crushed neoprene drysuit: 10 percent of your body weight plus 3 to 5 pounds (1 to 3 kg)
- Trilaminate drysuit: 10 percent of your body weight plus 3 to 5 pounds (1 to 3 kg)

How to Conduct a Buoyancy Check
Once you have an estimate, it’s essential to conduct a buoyancy check:
- Ensure your gear is on and your regulator is in your mouth.
- Completely deflate your BCD and, if applicable, vent your drysuit.
- Take a normal breath and see if you hover at eye level or slightly above the surface.
- Demonstrate negative buoyancy by exhaling and sinking past eye level.
- Adjust weights as needed until you can leave the surface gently when exhaling.
Consider Your Cylinder
Remember to account for your cylinder’s buoyancy:
- Aluminum cylinders are more buoyant than steel, so adjust your weight accordingly.

Recording Your Ideal Weight
Once you’ve found your ideal weight, make a note of it:
- Record your weight for each gear combination and environment.
- Always check your buoyancy when changing environments or gear setups.
Proper weighting when diving is not a one-size-fits-all approach. It’s a skill that requires understanding the science, conducting checks, and constant adjustment. By following these tips and guidelines, you’ll be on your way to achieving better buoyancy control, smoother dives, and a safer underwater experience.
