Scuba & Snorkelling Dive Computers

Scuba diving and snorkelling are both popular water sports that allow you to explore the underwater world. While they may seem similar, there are some key differences between the two activities. Scuba diving requires the use of specialised equipment, such as a dive computer, mask, fins, and snorkel, and is typically done in deeper waters. snorkelling, on the other hand, can be done with just a mask and snorkel and is often done in shallow waters.

Dive computers are an essential piece of equipment for scuba diving, as they help to monitor your depth, time underwater and air supply as it can show you your remaining air. Masks help to keep water out of your eyes and nose, and fins allow you to move more easily through the water. Snorkels help you to breathe more easily while swimming on the surface.

When choosing a dive computer, it is important to consider the features that are important to you. Most dive computers have features that allow you to track your dive data, while others have more basic features. It is also important to consider the size of the dive computer and how easy it is to use.

A personal dive computer is your best buddy. You must be able to quickly and easily read and understand your dive computer, whether monitoring your depth, the length of an underwater excursion, calculating nitrogen absorption, or measuring air supply.

If you purchase a console computer and don’t intend to take your regs on your next diving trip, you’ll either need to hire and utilise a dive computer that you are unfamiliar with or remove the console from your regs and place it on the hire regs.

Advanced recreational divers on the other hand, should have little problem owning and utilising their dive computers on every dive. Their equipment is equipped with GPS, Bluetooth connectivity for easy downloading and a digital compass, they have back-up computers, their dive log is in the cloud, and they’ve even ditched their paper charts and tables.

For those looking for a bit more simplicity, a wristwatch-style dive computer is often the best choice. These types of dive computers are easy to use and usually have all the features that you need.

Wrist mounted dive computer with large display. Choose a dive computer with a large display so that you can easily see your depth, time and other important information. A backlight is also useful for diving in low-light conditions.

When choosing a dive computer, it is also important to consider the battery life. Most dive computers use CR2032 batteries, which are relatively inexpensive and easy to find. However, some dive computers use AA or AAA batteries, which may be more difficult to find in a pinch.

It is also important to consider the warranty when choosing a dive computer. Some manufacturers offer limited warranties, while others offer lifetime warranties. Choose a dive computer with a warranty that suits your needs.

When choosing a diving computer, it is important to consider the type of diving that you will be doing. If you plan on doing a lot of deep sea diving, then you will need a computer that can handle the depths. If you plan on doing a lot of night diving, then you will need a computer that has a backlight. It is also important to consider the size of the dive computer and how easy it is to use.

The most important thing to remember when choosing a dive computer is to find one that fits your needs and preferences. There is no one perfect dive computer for everyone, so it is important to find one that has the features that you want and that you are comfortable using. With so many different dive computers on the market, there is sure to be one that is perfect for you.

If you are looking for convenient and easy-to-use technology possible, computer feature an intuitive interface and standard user-changeable batteries. Download your dive profile wirelessly to your smartphone or tablet.

Snorkelling is a great way to enjoy the underwater world without the need for specialised equipment or training. However, it is important to be aware of your surroundings and to stay safe while snorkelling. Be sure to choose a safe location, such as a beach with lifeguards, always snorkel with a buddy and basic equipment.

Safer Dives

A computer is also safer for your dives if you use them correctly. You eliminate the risk of human error inherent in manual computations, as well as the need to rely on someone else to do it for you. 

Given the possibility that a dive computer may get it wrong, and even if it does, if you and your buddy both have one, the problem is essentially solved. You two each have computers, and they both agree; therefore it’s very unlikely that both machines are wrong at the same time.

Longer Dives

You may go deeper. Because the dive tables assume you’ll stay at the same depth for the entire dive. Every single diver in the world understands that this is rarely the case. Computers in scuba gear calculate the initial plunge and any other rising and succumbing you do during your dive. 

The bottom time is constantly updated (like a GPS!) according to your present depth, taking into account all of your prior depths and times. It does things your mind can’t even fathom. It does more than my mind could ever comprehend, to be honest.

Maintenance

Begin by reading the instruction booklet. Check out each feature with all of the buttons pushed. Create a few preferences, such as time and date, metric or imperial units, fresh or saltwater, etc.

After each dive, rinse your dive computer in clean water as soon as possible. It should be kept out of the sun, especially the display screen. Keep it safe from harm and mishap.

The manufacturer’s instructions should be followed when changing or recharging your dive computer’s battery.

Required

Before diving with them, many dive operators insist that you use a dive computer, particularly if you’ll be doing more complex dives. Sometimes you can rent one, but wouldn’t you want to use a computer that you’re comfortable with. 

It will be a shame to discover on your next diving vacation that the dive business you booked with requires you to have a computer and you don’t have one. So make sure what the restrictions are at the shops you plan to visit beforehand.

Eliminate dive profile mistakes

The dive computer eliminates human error, including pressure groups and maintaining theoretical nitrogen loads for repeat dives. So, when the dive computer beeps or flashes an indication, take notice of it since it is correct.

Caution 

Diving computers aren’t perfect. Their job is to assist you avoid being bent by continuously calculating your bottom time and depth during rapid and continuous computations. They are unable, however, to consider other DCS risk variables such as weight, age, hydration levels, or the fact that you partied all night.

It does not know anything about your particular body or health, so it shouldn’t be considered a substitute for good diving knowledge. As with any tool, dive computers should be viewed as a tool and nothing more. Before using it, educate yourself on how to use it and never allow it to take the place of sound diving expertise. 

Ensure that your training and knowledge are current, then use the computer to assist you in utilising it in a safe manner.
