If you mention Diving gear to the average person, they will be able to give you a pretty comprehensive list of the gear a diver would need to reach the depths safely. Wet Suit, diving mask, and oxygen tank. Gloves and flippers. But what about a diving computer?
You might have heard of a diving computer before, but maybe you are unsure what they actually do? Do not worry, and you are not alone in that sentiment. There are some veteran divers who wouldn’t be able to tell you.
We are going to be looking at the 5 Best Dive Computers for Beginners. If you are a diving veteran and are looking to upgrade your current diving computer, I’m afraid you won’t find one here. But if you are new to the sport, we have what you need.
But before we can show you the computers, we need to clear up precisely what Diving computers are and what they do.
Buyers Guide for the Best Diving Computer for Beginners
A diving computer, to put it simply, is a small wrist computer designed to track all the vital information you will need while diving. It tracks your current Depth, remaining air, temperature, and speed.
The primary use is to monitor your air intake. It doesn’t connect directly to the tank but instead uses a depth sensor and a series of timers to tell you when to change your mix and when to ascend.
The diving computer also assists in your accent. Since you sometimes have to make multiple stops on your way up, the computer can tell you exactly when to stop and when to swim.
So what different features will you find within a diving computer? Let’s break it down.
Diving computers make use of various decompression algorithms to work out when you need to ascend and how much gas you are using. These algorithms are based on your body composition, and the companies own coding. To this end, some computers are more conservative than others when it comes to accent warnings.
The type of algorithm available will be brand-dependent. But two popular algorithms that have popped up in recent years are the Pelagic DSAT and the Pelagic Z+.
DSAT is designed for warmer, more relaxed diving, and it gives the user more control over how conservative it is. The Z+ is designed for colder waters and is helpful for more intense and skilled dives. The Z+’s big selling point is its ability to match the algorithms of other watches, letting you sync your warnings with your friend.
When diving, you won’t simply use a canister full of oxygen. Rather it will be a mix of gasses—nitrogen, Oxygen, Helium, and sometimes hydrogen. The mix you use and when you use it will depend on your diving experience and how far down you are planning to go. As a beginner, you will likely only use a nitrogen mix Or Nitrox. Most watches have the algorithms to switch between oxygen-heavy mixes and Nitrox. Some even allow for the usage of Trimex.
Suunto is a name you will see pop up a lot in terms of diving computers and diving in general. They are a leading brand in the field and create some of the best products. The RGBM algorithm is a specialized algorithm designed to deal with the dissolved gasses against free gas. Units like the Suunto zoop novo make use of the RGBM algorithm to significant effect. You won’t necessarily need the RGBM algorithm as a beginner, but it’s great to have if it is included.
When selecting your diving computer, you will need to take into consideration what type of display screen you want and what will work best for your skills.
A segmented display screen is a standard used for beginners. These offer essential information in an easy-to-read fashion, much like a digital watch. The downside to this type of screen is the inability to display more complex information.
Colour screens use colors to highlight the more vital information as and when you need it. They also work best in darker areas, so night dives or intense diving situations. You won’t necessarily need this as a beginner, but a color screen will still work great. They also eat up more battery life, so be aware of that.
When it comes to diving, weight is essential. Water makes you more buoyant naturally, but you aren’t free from the effects of gravity by any stretch of the imagination. The more your equipment weighs overall, the faster you can descend. But, keep in mind, every extra pound of weight will make your accent to the surface a bit more of a struggle.
Of course, as you use up the air in your tank, you will lose a bit of weight. But the difference in weight added by gasses is so minute, and it could be said to be redundant. So, you will want to take the weight of your selected watch into consideration.
Mounted or Wrist
The more common type of dive computers used by beginners are mounted. These units attach to your dive regulator via a special hose.
Mounted units are able to check your tank pressure to keep track of it, but they will need a specialized Air Integration system.
Wrist-mounted ones are smaller but much more accessible, being right at hand. They are often used by those who are far more skilled at diving. They are multi-purpose, being able to function for other sports as well. Of course, this means they miss out on some of the more advanced features of a mounted diving computer.
For beginners, either type can work, and it depends on what they offer and the type of diving you are planning on doing. The most common type used by beginners is wrist computers, due to their ease of reading and simplicity to use. But these models often offer limited functionality.
So, with that all out of the way, let’s dive into the 5 Best Diving Computers for Beginners.
