Factors to Consider Before Buying a Dive Computer
First, you’ll need to consider what type of dive computer you want. There are four main types: wrist-mounted, console sign, console integrated and deck mounted. The type of computer you choose is generally going to depend on the type of diving that you do most often. If you’re scuba diving, then a wrist-mounted or console-signal dive computer that can survive underwater is best for you. If you spend time doing recreational shore dives or snorkeling where the water is shallow and still, then a console-integrated or deck mounted dive computer may be best for you.
Next, consider how easy the product is to use. It’s not just important that it’s user-friendly but also easy to read. The display should be easy enough for you to see, and the computer should have a function that allows you to switch from metric measurements (metres) or imperial measurements (feet).
The size of the dive computer is also important. If it’s going on your wrist, make sure that it doesn’t get in the way while diving because divers need their hands free during scuba dives! You’ll also want a smaller model if you’re not wearing much gear when swimming underwater- like just goggles and fins. However, some people prefer a larger screen so they can view more information at once without having to stop what they’re doing with one hand- this might work well for those who are deep sea divers who wear bulky equipment.
Lastly, consider the battery. The best dive computers are powered by lithium ion batteries that last longer and won’t corrode like other metal-based batteries will. Some of them have a long life span (over 20 hours), while others need to be recharged more often or can only power the computer for up to six hours before needing another charge. Consider what your needs are as well: if you’re diving in saltwater then a water resistant model is necessary, but if it’s freshwater than one with less resistance may work better.
