The Best Dive Computers in 2023
There is no diving without a dive computer in 2023! The advantages are numerous and the models are able to satisfy beginners, experts and also technical or commercial divers. Let’s see together why we should use a computer, how to find the right one and what the best dive computers are in 2023.
3 Reasons Divers Use a Dive Computer
A Dive Computer Improves Safety While Diving
As every certified diver knows, dive computers are a huge asset to our safety and health while diving. We learn in our dive classes how to use them to plan or monitor our dives, as they basically record the levels of nitrogen we take in during a certain dive and warn us if we are getting too close to our limits, or calculate decompression if necessary. Dive computers in 2023 operate based on several up-to-date algorithms, they can work on different gas blends, at least air and nitrox, and have a plethora of functions and options. Dive computers are nowadays part of the basic diving equipment, they are one of the first items that divers will purchase, even before BCDs and regulators, as they are an extremely personal piece of equipment.A Dive Computer Gives You a Better Experience in The Water
A dive computer will not replace what you learn in class. You’ll still need to remember all the basics of diving measurement and plan your dive properly. But the dive computer will make your experience more enjoyable by simplifying things. For example, a dive computers’ advanced automated functions can save your from a more lengthy calculation of Nitrox mix.A Dive Computer Records Your Dive in a Dive Log
Most computers will also allow you to keep a log of your dives. That’s a great way to keep records on your dive experience, depth, the marine life you’ve seen, etc.Difference Between a Dive Computer and a Common Diving Watch
Many people call dive computers dive watches, not realizing there is a substantial difference between the two products. This is common between non divers or beginner divers. While dive watches are mostly watches that are not only waterproof but can go in-depth and are safe to dive with, they don’t provide the gas absorption information and do not calculate tour exposure to pressure and gases as a dive computer does instead. Dive watches are a good accessory to have, especially as a backup for computers: in recreational diving, for instance, if your computer fails during your ascent but you have a depth gauge and a dive watch, you can easily still perform your safety stop at 5 meters – 15 feet – for the required 3 minutes, as per standards. A dive computer is much more than a dive watch. It calculates your current depth, the bottom time, it tells you in real-time how long you are allowed to stay at that particular depth and when it’s time to ascend. It will monitor your ascent rate and warn you if you are going too fast, which could cause decompression sickness and end up in hospital. It’s an instrument that strongly contributes to your safety underwater.- Are you a beginner? We have an article specifically about the Best Dive Computers for Beginners.
What About Air Integrated Dive Computers
What is an Air Integrated Dive Computer
Air integrated dive computers are advanced diving watches that give tank and decompression information to the diver. Air integration means that the computer can factor in your air usage rate and calculate how long your air supply will last. A dive computer will display how much air/nitrox is left in your tank; your time to bottom, and current PSI readings. Once you’re back on shore, your dive computer can inform you about remaining desaturation and no-fly times.How do Air Integrated Dive Computers Work
Wireless air integrated dive computers are the most popular type; they use a wireless plug-in transmitter or a hose attachment that sends information to the dive computer. So they come in two parts: the computer and the regulator attachment. The signal is sent to the dive computer via Bluetooth or radiofrequency.What do Bluetooth Dive Computers Do
You can plan several aspects of your dive and upload the relevant data and settings onto your dive computer: water type, air, certain safety factors, etc. Post-dive, you can sync your Bluetooth dive computer with your phone or tablet, or connect your dive computer to your computer with a cable to load your dive log onto your device of choice.Do Beginners Need an Air Integrated Dive Computer
Although air integrated dive computers are not a requirement for beginner divers, we recommend them for a few reasons. First, they take the guesswork out of air consumption. Second, they provide reliable, safe diving support. Finally, a lot of dive guides require dive computers for beginners.What Are The Two Types of Air Integrated Dive Computers
The two main types of air integrated dive computers are wrist-mounted and console-mounted. Both are advanced diving computers and the main difference between them is where and how they’re worn. Wrist dive computers are popular because they are easy to wear and, being a watch, they can be of use outside the water. However, console dive computers are generally less expensive and therefore a good option for beginner divers. One thing to consider is that dive computer consoles that are hose-mounted have more parts at risk of wearing out.Best Dive Computers in 2023
