When diving, you can choose between a wing and jacket-style buoyancy control device (BCD). Wings are typically simpler and better for technical diving. They are more streamlined and provide even buoyancy. Jackets offer more pockets and support for casual divers. Decide based on your diving style and comfort.

Scuba diving can be risky, and divers must be prepared for emergencies. Common problems include a stuck autoinflator valve and a buoyancy compensator (BC) that won’t inflate. To avoid these, properly maintain your gear and check it before diving. If issues arise, try to control your ascent or descent and use the lanyard for the […]

Trim is the posture a diver maintains in the water. It is different from buoyancy, which is about floating up or down. Proper trim involves keeping your body horizontal and aligned. This helps with air efficiency and visibility while diving. Good trim also protects marine life and reduces air consumption.

Good buoyancy control is very important for filming underwater videos. Holding the camera steady requires hovering without swimming for long periods. You can adjust buoyancy by breathing in or out, and over-weighting may help in strong currents. Always be aware of your surroundings; avoid kicking up silt that reduces visibility. If you’re not horizontal, consider […]

Neutral buoyancy is crucial for public safety divers as it allows them to maintain a balanced position underwater without rising or sinking. This balance is achieved by managing buoyancy through the wing or BCD, dry suit, and lung volume. Proper trim, or body position, minimizes disturbances to the environment and improves search efficiency. Maintaining good […]

A recent video reveals a group of divers exhibiting poor scuba diving skills. Observers noted various issues, such as improper buoyancy control, excessive hand movements, and a lack of respect for marine life. Some commenters suggest that these individuals likely participated in a resort-style ‘Discover Scuba’ course, which often lacks sufficient training. Experienced divers express […]

In freediving, finding the right amount of weight is crucial for safety and performance. Freedivers perform three weight checks: the surface safety weight check, the 5m safety weight check, and the 10m performance weight check. The surface and 5m checks ensure that a diver can safely float back to the surface if they experience a […]

Handling vertical currents while diving can be tricky, but it’s important to know how to manage them. These currents can either push you down or pull you up and often occur near walls or ocean pinnacles. To navigate safely, swim away at a 45-degree angle from the current and adjust your buoyancy accordingly. Watching a […]

Argonauts, or paper nautili, are a special type of shelled octopus. Female argonauts create thin shells that serve as their eggcases and help them stay buoyant in tropical waters. These creatures are often seen during blackwater dives and are known for their unique mating and feeding habits. Males are much smaller than females and only […]

Breathing techniques are essential for improving your scuba diving experience. New divers often take big breaths, which can affect buoyancy and lead to wasted air. Instead, focus on deep belly breathing, which enhances efficiency by minimizing carbon dioxide buildup. This helps divers feel less “starved” for air and allows for better control while photographing marine […]
