What Is a Dive Computer?

A Dive computer, individual decompression computer, or decompression meter is a gadget used by an underwater diver to quantify the time. In-depth during a dive and use this information to figure and show a rising profile, which will give a generally safe decompression affliction as per the customized decompression calculation. The greatest invention in Scuba diving is Dive Computer, which is going on your wrists. This thing has a sensor in it that knows how deep it is in the water, and as you change depth throughout the dive, it continually calculates how much nitrogen is going into your blood at each depth, and then it tells you when you need to come up.

How to Choose the Best Dive Computer for Beginners?

The best dive computer for Beginners is those who can easily understand how it works. It should be a user-friendly interface designed on a low profile and much more compact than the other devices available. The gadget is easier to use when contrasted with the other Diving computers in a close value range. Its security setting should be easy to adjust and flexible. You can add extra decompression quits during our dive to create a base danger of decompression ailment. You can set showcase sound alerts for base time, rising rate, profundity, and a lot more things.

Devices should be super easy to use where beginners can easily understand the menu and operate a Dive computer while diving under the deep sea. Generally specialized (and more costly) Diving Computers are “incorporated,” which implies that they interface with your controller and air flexibly. A Diving computer with air framework incorporation can follow the air in your tank and give you dead-on figures. Most recreational models do not have air framework incorporation, which minimizes your Dive-Computer expenses and the remainder of your gear.

The essential showcase includes:

Best dive computers for Beginners should show you the rudiments initially. Those are the most extreme depth, current depth, diving time, and no-fly/no-stop time.

Super Easy to Use

You must keep in mind whether it is easy to read display with a big screen and big fonts with crucial information and sharp matrix screen. It must be ensured you get simple, precise information, clear and easy to read Logbook with scrollable graphs and memory.

Understandable Algorithms

No complicated Scuba diving algorithms which are difficult to understand by the beginners. The less experienced you are, the more traditional a Dive Computer you need. It would help if you never took any risks when you’re beginning. Indeed, even experienced jumpers like me frequently use more moderate calculation algorithms to remain safe.

Display

Backlight and glow display, you probably will not think you need one. However, a backdrop illumination is something you genuinely need to have if something turns out badly.

User-Friendly

Preference for the beginners Diving should go for the Diving-Computers which have a user-friendly interface. So, it would be easy to operate and interact with the device in less time and can be used easily.

Water-Enactment

Water-activated computers turn on and begin computing when they hit the surface. Since we all neglect to turn things on occasion, this is one accommodation you would prefer not to manage without. It is smarter to pay more and have the option to believe your Dive computer to work in any event when you forget to activate the mode.

Alert Cautions

Cautions are the component that ensures you will see critical alarms when you must because even the most mindful Diver incidentally forgets to take a gander at their computers. Search for cautions that are movable and simple to program. It would help if you had the option to utilize whatever will grab your eye, regardless of whether it is clamor or blazing lights.

Consider Air System Integration

A few Dive Computers are “autonomous,” which implies that they take a shot at their own. They will supplant a couple of bits of your plunge hardware (Depth, gauge, check & compass), yet they will not interface with your air framework. For most recreational divers, they are all you truly require.

Style

There are many different kinds of designs when it comes to scuba diving computers; however, the wrist and watch style works best for beginners and recreational divers. 

Wrist style computers are a bit heavy and bulky as compare to watch style computers that makes them easy to read during the dive. The wrist and the watch model are often more robust and durable; however, they don’t have an emphasis on fashion. 

Still, the watch style computer for diving is compact and stylish so much that you may want to wear them every day underwater and outside of water. However, beginners can have difficulty with small watch computer, especially in cold water and low light. So when you pick your dive computer, keep your personal preferences in mind and think of how often will you be using it and in where, and decide accordingly.

If you want to use your device daily or your diving cause an impact on your gear, look for an option that is long-lasting. Look up the warranty of your desired model before buying.

Types of Diving

There are so many diving types you can try, from night dives to ice dives and deep dives; here are the few common types of diving.

Night Diving

It is what it seems like; however, there is something else entirely to the late evening diving experience than merely hopping into the water around evening night time.

Deep Diving

How profound deep would you be able to go? A jump is viewed as a ‘Deep Dive’ when the scuba diver goes farther than 18 meters underneath the surface level. Most deep dives will occur at 30 meters or more underneath ocean level.

Cave Diving

Most scuba divers are cave diving fans, which takes you exploring the sea’s numerous ways, aperture, and passes. Lowered caverns can be discovered everywhere on the sea, and specific objections are known for having mostly amazing ocean gives in that draw in divers from around the world. It resembles a submerged play area or maze that you can explore.

Wreck Diving

There is nothing so interesting, secretive, and delightful as a submerged boat submerged, with the entirety of its components still there to find and explore. Typically, wrecks will have pulled in a different environment of fish, coral, plants, and ocean life, making them staggering spots to explore.

Ice Diving

Ice diving is for those insane cold searchers who need to investigate cold sea conditions underneath sheets of ice.

How to Use a Dive Computer?

Dive-Computers come with a screen that shows information digitally. Most Dive-Computers have three modes.

  • Pre dive mode: which is where you look at your gas?
  • Dive mode: which is where you look at dive time depth and the ascent rent?
  • Dive Log: which is where you get the information that was recorded during those dives?

That you can put it into your dive logs and physical dive logs, and your instructors can sign them, so let’s take a look at each one of these computers individually. Remember that these computers have the dive tables built into them; we don’t need table-charts anymore. This is one button computer, and when you press the button, it goes to the pre-dive mode.

From there, you press the button three times, and you get to the log mode. When you get there, you can see on the screen it says log to get into the log mode; you hold down the button and what comes up is the history of all the dives on that computer when you press the button one more time. It goes into the first log dive. All of the information recorded by the computer in the dive mode will be there for you to record into your logbooks.

What is a Dive Computer Used for?

Dive Computer which is going on your wrists, basically this it has a sensor in it that knows how deep it is in the water. As you change depth throughout the dive, it continuously calculates the depth, time pressure, and measures how much nitrogen is going into your blood at each depth. Dive Computers address a similar issue as decompression tables. However, they can play out a nonstop figuring of the incomplete weight of inert gases in the body dependent on the Diver’s real profundity and time profile.

As the Dive Computer naturally quantifies profundity and time, it can caution of unreasonable rising rates and missed decompression stops. The Diver has less motivation to convey a different dive computer watch and profundity check. Best dive computer for beginners gives extra data to the Diver, including air and water temperature, information used to help forestall oxygen poisonous, a Computer-readable dive log, and the weight of the excess breathing gas in the diving chamber. This recorded data can be used for the Diver’s very own Logbook of their exercises or essential data in the clinical survey. Or legitimate cases following diving mishaps that keep Diver safe, so this is a vital piece of gear. It means you don’t longer need to use Tables- Charts because Dive-Computers continuously calculate it.

What are the Technical Features Of Dive Computers

This is especially great for divers who travel to exotic locations where there is no service centre. This way your diving adventures won’t ever be spoil because of low battery.         

Adjustable Safety Settings

All the dive computers are designed to ensure safe diving; however, some models let you choose exactly how conservative you want your dive to be.in simple words with adjustable safety settings you can go on a lowest risk diving plan.

Some models let you make multiple decompression stops, lower the ascent rate and set multiple kinds of display and sound alarms.          

Air-Integration

The devices have air integration feature keep track of tank pressure during the dive via Bluetooth. So you will be able to see how much air is left for you. Some divers prefer this feature so that they don’t have to take up a pressure gauge underwater. 

However, air integration is not meant for every diver. You need to buy a wireless transmitter for this feature. So keep your budget in mind when deciding to go for air integration in dive computers or not.
