Best Diving Computers in 2019


Investing in the best diving computers is one of the best ways to ensure that you remain safe under the waters. With a good device, you will not have to worry about calculating your nitrogen levels using complex dive tables. Being able to keep track of information during your underwater adventure is the only sure way to avoid decompression sickness. Moreover, you will be in a better position to fill your dive efficiently.

When you have a nice dive computer, you really do not need to buy a dive watch, unless you want to have one for back up. A dive computer will let you know when you have to go up, when your air is running out, your depth and many more details. Having a good scuba tank is good, but you need a computer to manage your diving experience.

CLICK TO BUY ON AMAZON

 

If you are looking to purchase an entry level dive computer, then you should go for the Cressi Leonardo. The Leonardo was my first device to buy after I got certified as a scuba diver and I wouldn’t mind to recommend it to beginners.

Most dive watches including the Cressi Leonardo have advanced over the years. Today, this model is one of the most powerful scuba accessories you can own. The device comes in form of a wrist mounted watch designed and produced by Cressi which is an Italian company that deals with diving gear like wetsuits for diving, scuba booties, snorkeling sets and scuba tank regulators. They also make fantastic and durable buoyancy control devices (BCD).

Capabilities

The Leornardo watch has a large interface that displays a lot of data simultaneously. You’ll note that it can function in three different dive modes which include:

  • Air
  • Gauge
  • Nitrox

The oversized display allows you to access all the important information such as mode and time. The only problem that I noted about the display is that it becomes hard to read when the waters get dark and murky.

Cressi Leonardo scuba diving computer is designed to supply you with information on decompression status, depth, time between dives, ascent rate, and dive times. Additionally, it also displays the battery status to keep you aware when to switch off the computer before the battery runs out.

This computer features a one-button menu navigation system that makes it easy to use. You can press to toggle between the menus and hold to select menu. At least you won’t get lost in between the menus if you are a new diver.

The other awesome features are the screen warnings and audible alarms that are meant to alert you about safety stops and when approaching deco. For starters, the device has an ascent-rate indicator that uses an ascending stack of arrows to alert you. Secondly, it features an oxygen-toxicity bar graph as well as an audible alarm that informs you about toxicity levels.

Technical Capabilities

The Cressi Leonardo features marvelous technical capabilities that will help you become a better diver. For starters, you can use a connection device to transfer your dive log to your computer. This way, it will be easy for you to change that’s data to run dive simulations and help you in planning future dives.

The computer comes with a built-in dive log that has the ability to record data for 60 dives which is approximately 75 hours. This data is sampled at an interval of 20 seconds during a dive so as to provide a credible record of your historic dives.

Cressi features a Haldane algorithm which is programmed to calculate safe decompression limits even when you undertaking multiple dives within a few days. The algorithm is able to process your system’s nitrogen absorption and release continuously to ensure that you have a safe dive.

Pros

  • Multiple modes
  • Cressi’s own RGBM algorithm
  • Connects easily to your computer
  • Can be reset after each dive
  • Simple one button navigation
  • Features safety factory settings

Cons

  • Dull backlight
  • No Air integration & compass
  • No Safety-stop timer

  • Watch
  • Gauge
  • Norm

With the Veo 2.0, you do not have to take it to a service center for battery replacement because you can do it by yourself. This will save you a lot of time and money.

We found the navigation buttons easy to master. It has a button, which you can use to switch on the backlight, another one used to save a setting and two other buttons to move back and forth in the menu options.

The Geo 2.0 features visual and audible alarms that will warn you when something is not right. Luckily, you have the freedom to set alarms for air or nitrox diving which include:

  • Decompression violation
  • Too fast ascent
  • PO2 limit violation
  • Dive time exceeded
  • Maximum Depth violation
  • Violation of deep stop

ShearWater Perdix AI dive computer

CLICK TO BUY ON AMAZON

Having been in scuba diving for long, we have had the chance to test the Shearwater Perdix AI in various technical diving spots such as the Blue Grotto Dive Resort located in Central Florida. We are therefore glad to bring you a detailed review of this air integrated computer.

During our tests, we put the Perdix Ai and other dive computer into a series of simulated dives to evaluate its performance. We were able to evaluate the presentation of data, ease of use and how well we could see the display screen in various conditions.

To start with we noted that the Perdix AI was easy to read despite having a display that is filled with a lot of data. This advanced device features a 2-inches wide screen that allows you to customize the display colors. It uses the red and yellow colors to capture your attention during warnings

We liked how the alerts and warnings are displayed on an inverted background to help colorblind users. You can choose to personalize the screen to display additional information such as CNS and PO2 levels, dive time, and time. The bright color display allows you to view data easily even when you are in murky and dark waters.

The New Suunto EON Core Dive Computer Review

CLICK TO BUY ON AMAZON

 

The much hyped Suunto EON Core is the latest dive computer in the market 2018. Just as the name suggests, this device has so many specifications, features and functionalities that are similar to the EON Steel dive computer. The only difference is that it comes is a much smaller and lightweight format that a recreational diver would enjoy at an affordable price.

Capabilities

Having got the opportunity to test the EON steel dive computer for a week, we are comfortable to recommend this device since its usability matches the build quality. The first impression we got from this computer is how intuitive the menu is to use without the need to refer to the manual instruction. You’ve probably bought a new computer and encountered difficulties operating it.

As soon as we got the Suunto EON core, we were able to figure out all the basics within two minutes. It is not the kind of watch that you will have to press buttons randomly in order to see what does what. With this new advanced device, you just have to long or short press to activate various functions.

The Suunto EON core features a large and clear screen that comes with a black, white, or lime green bezel. It has a backlit LED screen that features a 320×240 resolution. You won’t have to struggle to read the information display when under the water. This is because the numbers are displayed in high-contrast and bold colors. The colors change depending on violation or proximity to various diving limits.

When you are diving in normal parameters, the display is usually in green, white and blue while the notifications are always in yellow. Alarms or warnings are always in red so that you do not confuse NDL violation and time to deco. You can adjust the brightness of the display to suit the conditions that you will be diving in.

Another advantage is that you can flip the display so that the buttons stay on whichever side you prefer. In case you wish to customize or re-program your display, you can do so using the Suunto’s Dive Manager Software. With this dive computer, you will have 17 different language settings available. Moreover, it also has a long but standard elastomer strap, which is so comfortable.

The EON core has a strong battery to support all the functionalities. It takes around 5 hours to charge the device fully. With the highest brightness setting, the charge will last for 14 hours, 27 hours in low brightness and 19 hours in default. Make sure you battery level does not drop below the minimum charge of two hours since the device will switch into gauge mode and lock all decompression calculations for  2 days.

This air integrated computer connects wirelessly with a maximum of 10 Suunto tank PODs to show gas and tank information. You can transfer your dive data or modify your settings using the Suunto Movescount App; you only need to connect using your Bluetooth with a mobile device.

Best diving computers buying guide

A dive computer is a device that you need to stay safe in the waters. You can choose to do without it and still enjoy your adventures under the water. Dive computers are device that play an important role in scuba diving navigation, gathering log information and decompression stop calculations. Such a tool should be a very convenient tool for all diving levels.

In case you are looking to purchase a good computer, you should take time to do your research and determine the features you would like in your device. At Scubadivinglovers.com, we have conducted our research and compiled a number of the important features. Hope you will find our buying guide helpful in your search for a versatile scuba dive computer.

Navigation

If you are a technical diver, you probably know the importance of having a compass integrated dive computer with you. A compass helps you navigate smoothly under water. Most of the advanced computers will come with a digital compass. It is therefore important to adjust the compass correctly to facilitate smooth operations.

If you are on a budget, you can consider buying the console versions that operate with analogue compasses. They will still work as expected. For beginner dive computers, they do not have an integrated compass. This is why they are sold at an affordable price since they miss out on some serious features.

Air/Nitrox integration

Air integration is also a key feature to look out for when buying a new scuba computer. For the basic dive computers, they do not come with air integration features. This means you have to use a pressure gauge as well as compass. To avoid using all these equipment, you should go for an air-integrated dive computer. Of course you will have to part with a good amount of money to buy such a device.

The good thing about air-integrated dive computers is that they will display important information such as the tank’s current PSI reading, air time remaining and bottom time remaining. In case you own a pressure gauge, you can opt for the non-air-integrated dive computers because they are less expensive.

If you opt to go for an air integrated dive computer, it is good that you decide if you will use air or nitrox mix.  Make sure you buy Nitrox –compatible computers if you dive using Nitrox or you may need it at some point. With such a computer, you can program the percentage of oxygen in your mix.

Data Transfer

Nowadays, all advanced dive computers will allow you to transfer dive data to your computer or cloud. You only have to connect your computer to your laptop or even smart phone to download all the data you require.  You will use a special USB cable to download data to your PC. Some dive computers allow Bluetooth transfer.

Replaceable batteries

Nowadays, most of the modern computers come with replaceable batteries. Unlike the old dive computers that you had to take to a service center for your batteries to be replace, today you can do it by yourself. Make sure that your computer has a watertight battery chamber; otherwise you might ruin your device if water gets into it. This is one of the reasons why divers still rely on service centers to get their batteries replaced.

Screen Guards for the best diving computers

If you want your dive computer to last for long, it is important for you to choose one with a scree guard. The guard protects your device from cracking or getting scratched, meaning it will last for a long time without the need for replacing. In case you buy a computer with no screen guard, you can buy a Perspex one separately.

Readability

It does not make sense to purchase a dive computer that will be difficult to read under the water. This is why we consider readability as a very important factor when buying a new scuba dive computer.

You should be able to read the data on your display even when wearing a mask. Some of the computers have backlight on the display which is very important when diving in murky waters. A readable screen has big digits, a back lit display and a wider angle color screen.

Wrist or console-mounted?

Scuba computers are available in two models; a wrist mounted computer and a console mounted computer. The main difference between the two models is that the console mounted computer is large and is attached to your equipment through a hose. Most of the console dive computers have the air integration feature, although you will find some that don’t have.

The console mounted computers use batteries, which means at one time you will have to replace them. The pressure gauge of these console computers must be connected to your tank in order to show a pressure reading.

Wrist mounted dive computers are great for recreational divers who do not dive too deep. The good thing with the best diving computers (wrist-mounted dive) is that you can use them as day-to-day watches. For people who like to dive in wrecks or caves, it makes a lot of sense to use a wrist mounted computer. You won’t have to struggle to maneuver tight spaces.
