Best Beginner & Recreational Dive Computers

Most divers will start looking to buy their first dive computer shortly after completing their Open Water Diver Certificate. It's generally easy to go with whatever dive computer you used during your training. This is common and understandable, as it's the first one you'll have gained some familiarity with.

A lot of new divers are unsure how far they're going to take their diving.

Scuba Diving

For the majority of new divers, entry level dive computers are the best place to start.

Even if you think you'll move towards a more technical style of diving, entry level dive computers hold their value well. These are always in demand if you decide to upgrade later on.

If you do decide to upgrade later on, a quality dive computers will serve you well as a back-up dive computer. One thing worth remembering when considering a backup dive computer, is to make sure you go with the same algorithm so they match.

How do the Entry Level Dive Computers compare in Price and Functionality?

There's two levels of Dive Computers aimed at the entry level market, and this is reflected in both their pricing and functionality.

Entry Level Dive Computers

The first level are priced around the $200 USD mark and have all the basic functions, which cover everything new divers need. Some of the best in this range are the Cressi Leonardo, the Mares Puck Pro and the Aqualung i100 and i200. You need to keep an eye on the price for the i200 as it jumps around a bit.

Recreational Level Dive Computers

The second level in this range include the Suunto Zoop, the Cressi GiottoAqualung i300C, the Oceanic Geo 2.0, and Deepblu Cosmiq+. These are priced in the $270 USD to $360 USD range. 

The Deepblu COSMIQ+ and Aqua Lung's i300C are well worth considering if your dive computer budget is around the $350 USD mark.

The advantage these two have other other Recreational dive computers in this price range is that they both have Bluetooth connectivity.

Watch Sized Dive Computers

Best Watch Sized Dive Computer with Air Integration

There's usually a bit of a compromise when it comes to watch-sized dive computers. These dive computers aren't big and bulky and most can easily pass as an everyday watch during vacation. To fit into the watch-size category though, the display is smaller so these may be more suited to younger eyes.

Being 'watch sized' though, also means they're more expensive than other wrist mounted dive computers. If you're ok with this extra expense, then the dive computers listed below might be just what you're looking for. 

These watch-sized dive computers have more features than their entry-level counterparts, plus the option for wireless air integration.

Suunto D4i Novo, D5 & D6i Novo, 

Suunto D5 Dive Computer black and lime

Suunto D5 Dive Computer

Suunto has released new colors for the D4i Novo. The D6i Novo now comes with a range of Zulu straps which really appeals to a lot of people. I do like the look of the D6i Novo with a Zulu strap. These really hit the mark when it comes to having both the functionality and the look of an everyday watch.

The Suunto D5 has many advantages over the D4i and D6i. It has wireless air transmission, wireless mobile connection and the battery is easily rechargeable. 

Have a look at the table below to see how the 3 different Suunto models compare. These are all great dive watches.
