As a diver, your life depends largely on your gear. No matter how well-trained and experienced you are, if your gear malfunctions, your life will be in grave danger. This is why you need to learn as much as you can about scuba gear before you even start training and make sure you have all the right equipment when you go on a dive.
The most basic information you need where scuba diving is concerned is the specific pieces of equipment you’ll need. If you can afford to buy just one piece of equipment to begin with, then it’s best to get a mask. Make sure it’s comfortable and fits just right. A nice set of swim fins is also advisable, as it can make you more confident as you glide underwater.
Aside from a mask and a set of swim fins, you’d also do well to get a reliable dive computer, which helps you reduce the risk of decompression sickness and saves you from the hassle of having to calculate no-decompression limits using dive tables. Of course, a wetsuit is also advisable, as it helps keep you warm as you go deep underwater, where temperatures tend to be significantly lower than surface temperatures.
Additionally, you’re going to need regulators. Note, though, that this is an expensive piece of equipment. If diving isn’t something you’ll often be engaged in, then it may be a good idea to rent, rather than buy, regulators. Another expensive piece of equipment most divers use is the buoyancy compensator. Again, you may want to consider renting this piece of equipment instead of buying your own.
Other than the basic pieces of equipment, you may also want to include some accessories in your scuba diving gear. The most commonly used dive accessories are dive knives, whistles, surface marker buoys, underwater lights, writing slates, tank bangers, and other underwater signaling devices. Weights are also often necessary during a dive. You have the option of buying your own set of weights or simply using those that are available in most dive shops.
Tanks, of course, are a vital part of any dive. Tank rental is usually included in the price of a dive package. As a beginner, you could start out renting these pieces of equipment. If you find that the activity is something you’d like to do on a regular basis, then it would definitely be advisable to start buying your own gear.
