What To Look For In A Dive Computer?

SCUBA diving can be an enjoyable and exhilarating past time. When you first start out, you can rent the dive gear you need for a casual, recreational dive. As you become more experienced, you will need to start thinking about purchasing your own dive equipment. One of the most important pieces of equipment you will need to consider is a quality dive computer. Dive computers are complex and sophisticated pieces of equipment. You may be tempted to pick up a cheaper budget dive computer, but make sure you way up the pros and cons of what you are looking for in the device. BestPatrols has made it a bit easier for you and done the research on some of the top dive computers available on the market today.

First, you need to think about the way you dive. How often will you be using your dive computer? What depths do you intend on diving down to? What are the features you would like to have included? Maybe you only require a basic, entry-level, computer that monitors your oxygen levels, time, and dive depth. On the other end, you may like to consider upgrading to a more versatile, premium dive computer. Your goal should be to find a device that will do all the important calculations for you including time, depth, air and pressure, while you get to enjoy the underwater wonderland.

Technology has come a long way in recent years. Where diving instruments of the past were as basic as some weights and air hoses, today you have a variety of state of the art functions to make your dive safer and more enjoyable. A quality dive computer will have an illuminated screen, allowing you to be able to read it in low light conditions or murky waters. A clock or timer allows you to keep track of your time underwater and gas sensors ensure you don’t run out of breathable air without warning. Depth and pressure sensors make your dive safer by helping you stay within your limits and not resurface to rapidly when you need to acclimatize.

At the top end of the market you can get all the gadgets already mentioned and more. An Air or Gas integrated device will calculate your remaining oxygen/nitrogen levels based on your current usage. A dive computer that includes a RGBM (Reduced Gradient Bubble Model)-algorithm is essential for deep water dives. The RGBM alerts the diver to pressure changes that can cause potentially serious health impacts of rapid decompression. Blue-tooth integration allows you to sync you dive computer with your other devices. A built-in compass is invaluable for cave diving or investigating ship graveyards and other sunken debris. Audible alarms for low battery, air, and time are essential so that you can enjoy your dive without fear of losing track of your vital resources.

Finally, when shopping for dive gear, you need to look for quality workmanship and a reliable warrantee. Why would you spend money on a low-quality dive computer just to save a few dollars, only to discover at 60’ft that your ‘bargain’ is not actually fully waterproof or your compass is not accurate? Diving is a serious sport and your safety is not to be taken lightly. If you take your diving seriously, then you will probably want to look stylish as well. A premium dive computer will not only feel comfortable but also look impressive. You’ll want to wear it all the time, just so you can brag about it.
