Looking to unravel the underwater magic of Kauai’s vibrant reefs? Your journey with Fathom Five Divers, a leading dive shop in Kauai, Hawaii, begins with mastering one key skill – buoyancy control. Perfecting buoyancy is crucial to an enjoyable and respectful dive experience. Without proper control, you may find yourself jostling up and down, damaging precious reefs, and depleting your air supply faster.

Here are ten expert tips from Fathom Five Divers to enhance your buoyancy control during your scuba diving adventure


1. Choosing the Right Scuba Weights

Balance in buoyancy starts with selecting the correct scuba weights. The ideal scenario? With an empty tank and deflated BC, you should float with water at eye level. This ensures neutral buoyancy at the 15-foot safety stop. Always tweak your weights gradually, in 1-2 lb increments.

2. Keep a Dive Weight Journal

Maintain a record of the weights used during each dive, as this can serve as a reference for future dives, especially in new locations. Remember to jot down the thickness of your wetsuit too, as it affects the weights you require.

3. Rely Less on Your Buoyancy Compensator

Achieving perfect buoyancy often means using your BC less, not more. On your descent, gradually release air from your BC and allow time for it to work. Once you reach your desired depth, try not to tamper with your BC further.

4. Get Horizontal Underwater

As soon as you submerge, orient your body horizontally. This position helps you descend faster without over-deflating your BC, ensuring you remain neutrally buoyant at the bottom.

5. Manage Your Tank’s Buoyancy

As your tank lightens during the dive, ensure your descents are comfortable. Struggling to descend may mean you’ll find it hard to stay down towards the end of the dive.

6. Efficiently Release Air from Your BC

Extend your BC’s inflator hose upward while venting air. Simultaneously compressing your BC against your chest can help eliminate the last few air bubbles.

7. Mind Your Breathing

Breathing technique significantly affects your buoyancy. By merely inhaling or exhaling, you can ascend or descend a few feet. Exhale fully before inflating your BC. Remember, a lungful of air can add up to 10 pounds of buoyancy.

8. Stay Relaxed and Still

Excessive movement can inadvertently cause ascension. Maintaining calm and extending your legs while keeping your arms still can help prevent unintentional movement upwards.

9. Understand Your Wetsuit’s Role

Your wetsuit’s buoyancy changes as the bubbles within it compress with increasing pressure. Before adjusting your weights, remember that your wet wetsuit will become less buoyant.

10. Practice Makes Perfect

Like most things, perfecting buoyancy control comes with practice. The more dives you undertake, the more relaxed and comfortable you become underwater. This makes managing buoyancy almost intuitive.
