Best Dive Computer under $500

Finding the best dive computer under $500 should not be a challenge. That is if you are looking for a DC for recreational diving. Don’t expect to get a device that has features that you’ll need for technical diving.

We cover what you can expect from a device at that price point and what you won’t get. Lastly, we showcase three dive computers that stay under the $500 mark.

Mares Smart Wrist Dive Computer

What Features can you expect?

At this price point you’ll get the basics. You can expect a reliable device that will keep you safe during a dive.

Regarding specific features you can expect the following:

RGBM with Adjustments

A safe RGBM algorithm that continuously calculates your dive data to keep your dive within healthy limits. Pretty much each dive computer manufacturer has their own variation of a RGBM algorithm.

Some are more conservative than others. If you dive with a buddy that has a DC from a different brand then you have to expect your dive limit calculations to be different!

Most algorithms also offer the ability to change the conservatism of the calculations. The settings allow to change the limits within the algorithm to be more conservative which ultimately means they end up providing you a larger safety margin.

One or Multiple Gas Mixes

Most dive computers in this price range will provide the ability to have one nitrox mix. Usually they support oxygen levels up to 50%.

For most beginners and recreational divers being able to manage one gas mix is good enough. If you’re relatively new to the sport then diving with a single gas mix will cover you for usually the first few years if not even for a lifetime.

You find more and more dive computers that can handle up to two gas mixes. Most newer models are capable to do that. Depending on your dive needs this might or might not be an important feature for you. For recreational diving it often is of less importance to have this feature.

Audible and Visual Alarms

All dive computers in this price range offer various audible and visual alarms. Typically, you can expect the following types of alarms to be setup for a dive:

  • Dive Time​
  • High pO2
  • Violation of decompression ceiling
  • Maximum depth violation
  • Ascent too fast

These are the alarms that are most important for a recreational diver and they are usually all covered by a DC at this price point.

Dive Log

You should expect the DC to have a solid dive log with enough memory to store dive data for at least 20 dives. Some models even provide enough capacity for over 100 hours of dive data to be collected.

Usually, the dive data will be collected at a fixed rate. Some models will allow to adjust the collection rate.

Connectivity to Computer (optional)

Dive computers offering a dive log will also offer the (optional) ability to connect the DC to your computer. All brands have their own software to install on your PC and in most cases you can get the software for Windows or for the Mac.

What will you be missing?

Dive Planner

Usually you will not find a built-in dive planner in this price category. However, you should be able to offload the data to your computer and perform dive plans on the PC.

Air integration

Air integration is nothing you will find in this price category. You might get lucky and find a DC on sale that is capable of air integration but you most certainly will not get a device that has an air transmitter included.

Digital Compass

Integrated digital compasses are something you will have to look at the next price level. Usually, these devices will be more in the $800 to $1,000 range where you can see digital compasses being part of the feature set of the DC.

Conclusion

There’s a good selection of highly capable dive computers in the category under $500. Looking at any of the five devices shown above as well as the many other scuba computers in this price range will provide you with a solid dive computer that’ll last you for years to come.

Which device you eventually pick depends somewhat on your personal preferences. Ask yourself whether you want an oversized device like the Suunto Zoop Novo or the Cressi Giotto. Or do you prefer a watch sized model like any of the other three? Larger displays often allow for better reading of the information on the screen under water. It also often means that it’s easy for you to switch the battery. Watch sized dive computers often have to be sent to a service center or to a dive shop to have the battery changed.
