If you are in a hurry and just want to find out what the best dive computer is, then we recommend the Cressi Leonardo Dive Computer as the best one.

Are you in the market for a new dive computer? No matter if you are looking to replace your old dive computer or are looking for your first one you want the best dive computer there is. Dive computers are often times referred to as a diver’s best friend as they allow you to spend more time enjoying your dives and less times making dive calculations.


Choosing the best dive computer.

The key is finding the best dive computer with how many choices there are. Like many technology driven products selecting the best dive computer is not as easy as we would like, after all it’s a pretty complex piece of equipment.

For those of you who have already spent time reading through the specs of various dive computers, you know just how complicated they are. With how important dive computers are to scuba diving how do you know you are picking the best one?

Here are a few important factors to consider when selecting the best dive computer for you.

  • Diving level

The first thing you need to ask yourself when looking for the best dive computer is what is your current diving level, basically how much diving experience do you have. If you don’t answer yourself honestly it is very easy to end up with a diving computer that it too advanced for your current needs.

If you are a beginning diver the best dive computer is going to something simple and easy to use. Big displays are a good thing to have on a beginner’s dive computer because much of your time is going to be spent getting comfortable breathing and swimming underwater. The less you have to fiddle and worry about the better. Even as you gain experience you will never outgrow the basic dive computer, as it will always make a great backup.

If you are a tech diver or an advanced recreational diver the best dive computer for you is going to be quite different because your diving needs are a lot different. One thing to look for is Nitrox capabilities, you might not use it on every dive but you will end up needing it at some point. As a more experienced diver you are going to need and want more advanced features, including things like trimix, free dive modes, etc. As an advanced diver you need to look for dive computers that offer features most important to you.

  • Readable Underwater

As you are going to have to read the dive computer underwater, you want to make sure that the display can be read underwater. So without taking it for a test drive, how can you tell if the dive computer is able to be read underwater? You want to look for a display that is generally easy to read. The display will have high contrast colors with a backlit display and big numbers.

  • Easy to use

As with all computers, some dive computers are easier to use than others. The less time you have to figure out how to use the thing the more time you can spend using it on dives. One way to determine how easy the dive computer is to use is to read about other people’s experiences with it.

If majority of people are saying it’s hard to configure or switch modes you might want to reconsider the purchase. You also need to think about where you plan to use the dive computer. If you are going to be in cold water a lot that means thick gloves, so you need a dive computer with big buttons. The bigger the buttons the easier it will be to use with thick gloves on.

  • Set up/Style

Dive computers come in two different set ups or style. You have the wrist or console. The wrist computer provides you with all of the data right there on your arm. Wrist computers are easy to read and offered a more streamlined option. With the wrist style you can get the classic dive computer or one that looks like a wrist watch. A console computer is ideal for divers who prefer to keep all of their dive instruments in one central location.

  • Air integration

This feature is a newer one and should not be the main factor in determining the best dive computer for you. Wireless air integration is nice as it provides you with a transmitter to monitor how much air you have left in your tanks, but like all technology it isn’t perfect. The signal between your dive computer and the transmitter can be lost while diving.

  • Price/budget

Dive computers can be expensive and the more features they have the higher the price tag. Determine how much money you can afford to spend on a dive computer beforehand. If you are new to diving and have a relatively small budget you can easily find entry level dive computers with the most basic features. If price isn’t a concern look into the dive computers that offer some of the more advanced features, such as a digital compass, multi-gas capability, etc.
