To control my buoyancy as I ascend after a dive, I should. frequently let expanding air out of your BCD in small amounts to control your buoyancy.

9 Tips For Better Buoyancy Control

  1. Weight Yourself Correctly. ..
  2. Adjust weight according to equipment and conditions. ..
  3. Perform a buoyancy check.
  4. Perfect your body positioning.
  5. Familiarize yourself with your BCD.
  6. Master breath control.
  7. Don’t use your hands.
  8. Enroll in a course.
  9. LOG YOUR DIVE

Weight

The weights you wear in your BCD weight system or on a weight belt are often the biggest problem, so that’s the place to start.

When you have more weight than you need, buoyancy control is more difficult: Every extra pound has to be balanced with about a pint of BCD air. Since this volume expands and contracts with depth changes, you have to constantly compensate to keep the volume at one pint. Five extra pounds (which happens) means five un-need pints of volume that grow and shrink every time you change depth.

To check for proper weighting, with a nearly empty tank (500 psi) and an empty BCD at the surface, hold your breath (reg in mouth in case you sink). You should float at eye level and slowly sink when you exhale. If you check with a full cylinder, add 5 pounds to compensate for the weight change as you use up your air. This is because your cylinder gets lighter as you use the air in it. The air in an aluminum 80 weighs almost exactly 6 pounds and at 500 psi, it’s about five pounds less. So, you should start the dive about five pounds heavy.

Breath Control

Your lungs are a natural buoyancy compensator with as much as 10 pounds of buoyant lift. A normal, resting breath expands your lungs by about one pint, giving you one pound more buoyancy. Breathing in and out, your buoyancy fluctuates within a range of about one pound. So as long as you are nearly neutral with a half-breath, you can make fine-tune buoyancy adjustments just by controlling how deeply you breathe – but never hold your breath, of course.

What are Suunto dive computers used for?

Suunto dive computers are used to plan dive profiles, gases and back-up plans. After a dive, dive information can be downloaded back to someone’s computer.


Why can’t you and your buddy share a dive computer?

-because dive computers track your dive profile precisely and small differences of even a meter/few feet can affect time limits. -dive computers also track changing nitrogen levels between dives also
