Scuba Divers: 10 tips to better buoyancy

December 18th, 2009

On the first day of Scuba class, a student learns how important buoyancy is in diving. Once certified, a diver will spend a better portion of his/her training perfecting their buoyancy. Simple fact, buoyancy is more art than science. With good technique, the right training, ongoing practice and the right equipment, you can perfect your buoyancy. The goal of any diver is to hover effortlessly through the water. When you “dial in” your buoyancy, you will reap the benefits such as, better air consumption, dive with less exertion, protect the environment and safely control your ascents and descents, Great buoyancy means you are diving safer and having more fun.

Following are ten tips to assist you in developing better buoyancy:

1. Get more training: Most divers often use bad habits to compensate for poor technique. Without the right training, these bad habits become memorized and hard to break. Stumbling through the water becomes the status quo for many divers. Get enrolled in a class. Learn the right techniques to proper buoyancy. Perfect the ultimate skill for being a Scuba diver, without the crutch of bad habits. With more training, you will achieve the goal of spending as much time as possible, during your dive, neutrally buoyant.

2. Weight yourself correctly: One of the first skills you will learn in any buoyancy class is how to weight yourself correctly. if you are overweighted (one of the bad habits discussed above), you will need more air in your BCD to keep you off the bottom. More air in your BCD means more management as you ascend and descend. If you are weighted incorrectly you will spend little time neutrally buoyant. In fact, you will be struggling back and forth between being positively or negatively buoyant.

3. Spread your weight out: Many divers stack their weight in a single area on their body. Usually in a weight pocket or all on a weight belt. This misaligned weight placement usually causes the head to be in a downward or upward position. Seldom does it lead to perfectly horizontal position in the water. The rule of where the head leads, the body will follow applies when this happens. Thus, if the head is in an upward position, the diver will have a tendency to rise up, causing the air in his or her BCD to increase and making the diver positively buoyant. When this happens a diver must compensate by dumping air. When a diver has his or her head in a downward position, they often find themselves crashing into the bottom. Becoming a negatively buoyant diver. When a diver’s weight is “trimmed” correctly, they tend to be completely horizontal in the water and takes little or no effort to maintain a depth.

4. Own, don’t rent your gear: Every time a diver changes their gear configuration and exposure protection, their buoyancy changes. If you are constantly renting gear, you never have the same configuration thus your buoyancy characteristics become a wild card on every dive. The amount of weight needed, where weight can be placed, the buoyancy characteristics of the gear itself all change when you continuously rent gear. If you own your own gear, the configuration and the dive characteristics will be a constant on every dive. Buy right, buy once. Gear choice is an integral ingredient to mastering buoyancy and becoming an advanced diver.

5. Streamline your gear: Once you have purchased your own gear, you should take some time in the accessories section of your local dive shop. Find the right clips and snaps to “tighten” up your configuration. In order to protect the environment and your gear, it is important that loose gear is attached closely to the body. This practice is called streamlining. When you gear is streamlined, you will find that it does not create drag which can upset your relaxed neutral buoyancy.

6. Breathe control: Divers should always have control over their breathing. I have met some divers that have had great success learning yoga as a way to control their breathing. A good steady, continuous breathing pattern is a great way to maintain a constant depth and neutral buoyancy. As divers become more adept with diving, breath control is the way they make minor depth changes.

7. Stay in shape: This almost seems like an obvious tip and has benefits far outweighing just Scuba diving. Divers who are in shape require less weight, handle gear easily, breathe easier and have better buoyancy. A good, regular cardio-vascular workout is essential for mastering buoyancy technique.

8. Slow down: Most divers swim too fast. Not only do they miss things as they motor past them in the ocean, but swimming fast over-exerts divers. This could lead to abnormal air consumption and minimal bottom time. Further, if a diver becomes too over-exerted, it could lead to hyperventilation or a dangerous underwater scenario. In many instances, divers swim fast because it is a bad habit that they have picked up to overcompensate for poor buoyancy technique. Momentum is a bad habit that can keep a diver at a single depth, regardless if they are mildly negative or positive buoyant. Slow down, if a diver can’t maintain a constant depth while hovering, more training is probably required.

9. Observe other divers: Watching other divers and how they manage their buoyancy is a great way to learn great technique and observe bad habits. With the right mentor, observation can be a powerful training tool. Be mindful of what you are observing and take advice only from those folks who are qualified to give it.

10. Practice often: Skills rust when they are out of water. If divers do not practice your buoyancy skills and dive often, they will lose their perfected buoyancy. Divers should be in the water on a regular basis. It is recommended, divers practice their skills at least once per month. If a body of open water is not available, a pool is still a good option to practice skills.

Once you have your buoyancy perfected, drifting through the reefs of Cozumel, gliding down the steep walls of the Blue Hole in Belize and floating along side sea turtles in Hawaii become far more enjoyable.

Giant stride into a buoyancy clinic or specialty class and master neutral buoyancy.

What You Need to Know Before You Scuba Dive

November 22nd, 2009

Scuba diving is a sport that many people indulge in, and it is a fun experience for almost anyone, except perhaps those who can’t swim and are terrified of water. It isn’t without it’s risks, however, and like any outdoor hobby or sport, injuries can be sustained, sometimes even fatal ones, by undertrained or poorly equipped divers. For the noobies out there, here are a few preparatory steps that you must take and some information you need to make sure that you can enjoy your first dive in safety.

Certification and Training – take up a course that actually gives you certification to scuba dive. If you’re just doing scuba for kicks however, like maybe just renting gear out at a beach resort while on vacation, then make sure you are accompanied by one a professional instructor when you do your dive. Also, keep in mind that scuba divers must have skills in swimming and snorkelling as prerequisites for scuba diving. If you’re not proficient in both of these areas, it’s best to try them out first before doing something as serious and complex as scuba.

Equipment Checks – make sure that your equipment is in proper working order. As stated earlier, get proper training before doing a dive. Part of any good scuba instructional course includes the care and maintenance of equipment, as well as spotting potential weaknesses in equipment that can lead to it’s failure underwater. Many divers have suffered accidents during dives due to faulty air lines, but aside from that be sure to check the rest of your equipment just as thoroughly, down to your compass and first aid kit.

First Aid – you’ll need special training in treating underwater injuries, as well as the ability to recognize the signs and symptoms of common maladies incurred by divers, which include hypothermia, decompression sickness, and in hot weather, heat stoke and dehydration. Make sure your first aid kit is well stocked before the dive.

Know Ascents and Descents – part of diving successfully is to keep a pressure gauge and depth gauge that monitors water pressure around you and the depth you’re at. Water pressure increases drastically the deeper you go, and divers can sometimes suffer dizziness, shortness of breath, nausea, and muscle cramps from descending too quickly. On the opposite note, even with a good, controlled descent, a rapid ascent can also lead to system shock and trauma if the diver just suddenly dumps his diving weights and rockets to the surface. The body won’t be able to adjust to the sudden lack of pressure, especially once the diver leaves the water.

Buddy Diving – never dive alone if you’re a noobie. Always have a more experienced and trained diver with you. Keep your buddy in sight at all times, and be sure to follow his or her lead once the dive begins. Do NOT go off on your own, no matter how safe the surrounding waters seem to you. Tempting as it may sound for the adventurous, even if you and a friend take the same scuba course at the same time, remember that he or she does NOT count as a diving buddy if you’re both noobies. There’s nothing more dangerous in any outdoor exploratory sport than a pair of people blundering around in a dangerous environment.

Communication – learn the hand signals used underwater by divers to communicate. Even with a high tech open face scuba mask that has an integral comm radio, these hand signals are a must for any diver. For one, your radio may break down and run out of batteries. For another, you might run into a cute girl on your dive who’s not wearing a comm system…

Navigation – know how to navigate underwater. The training course that you take should include the recognition and use of simple tools like an underwater compass, as well as more advanced things like using underwater floater buoys and line markers that will allow you to backtrack to your starting point once you’re done with your dive. Losing sight of your buddy and getting lost underwater is scary, take my word for it, and having the capability to backtrack and meet up at a predetermined rendezvous point takes a load off your mind if this happens.
