Dive Computer Buying Guide 2018

Besides reading about a dive computer review from a reliable source, learning about the features and options, surrounding this device is similarly essential. There are several factors to understand when it comes to dive computers, especially now that the market is offering a wide selection of this item.

Air/Nitrox Integrated

Basically, a dive computer only records the time and depth. So, a Nitrox/air integrated dive computer should be the best choice as you don’t have to use another device for the pressure gauge, as well as for the compass. If you can do well without the pressure gauge, then choosing an air-integrated gear will do. This type of dive computer will let you run an air hose from the tank to the computer, though.

Take note that air-integrated computers have the ability to display information like air time remaining, PSI reading of the tank, and the bottom time remaining. On the other hand, non-air integrated computers would be lesser inexpensive choices. It could still be a good option for those who already have a pressure gauge. Air-integrated computers might experience a glitch, while at depth, although a rare occurrence, losing some valuable data such as the amount of air left.

Based on air integrated dive computer reviews, it is still necessary to choose between air and Nitrox mix if you are opting for an air-integrated computer. Using Nitrox during a dive requires a computer that will let you program the oxygen percentage in your mix. The Nitrox-compatible computers with air-diving are standardized, setting 21% of oxygen. However, the standard air-dive gears are unable to accommodate Nitrox. So, deciding on using Nitrox or not is primarily crucial, before knowing what is the best dive computer for you.

Navigation

An essential element during a scuba diving is the compass, allowing the diver to determine where he’s heading or getting back to the boat or shore. The best scuba diving gear of today will replace the old-fashioned compass, providing digital displays. A reliable dive computer should likewise supply this feature so as to maximize its efficiency.

Depth Gauge

The depth gauge simply records the depth, but a reliable dive computer must do this task more accurately, even at various depths. While reading about wrist dive computer reviews, it is essential to take note of this feature. The gear must be capable of carefully determining the time spent at every depth, while still allowing the user to enjoy the scenery at the same time.

Memory

The memory of a dive computer should also be taken into account. The log function will help you save and review the dives you have completed. However, the number of saved dives may vary by computer. So, before buying a dive computer, make sure that it can record enough dives as per your requirement. The best dive watches of today can retain at least 10 dives, compared to old dive computers that can only show the most recent activity.

PC Compatible

Dive computer comparison is also crucial in order to determine if the device is compatible with your personal computer. The majority of these diving gears have the capability to download the dive details to a PC, allowing you to create and save a permanent record. In this regard, software with interface is required, converting the dive details into graphs, while showing the different depths you have achieved throughout a dive as well as the time spent at each depth.

The best diving gear can also display the ascent rate violations or the rapid ascents and missed decompression stops. The more sophisticated computers can likewise display air consumption and the predicted nitrogen load in the tissues.

Calculations

The top divers watches should certainly do the Mathematics. The potentially life-saving calculation is not an exemption to this. Among the basic and most important functions of a dive computer is to calculate decompression. Thus, decompression stops greatly rely on the depth and the dive’s duration. Other dive computers can perform a revised decompression stop calculation once the diver accidentally misses a decompression stop or an ascend prior to a decompression stop was to end.

Another calculation that reliable dive watch computers can do are the no-fly times that are essential for every diver who relies on air travel towards the end of their scuba diving activities. Keep in mind that the body slowly releases nitrogen after a dive, and by ascending in a plane, the remaining nitrogen in the body can expand because of the lower pressure on the body as the airplane ascends. Thereby, the no-fly calculation of a dive computer will basically inform the diver when the safest time to fly is.

Mount Style

The mounting style of a scuba diving watch computer is either wrist-mounted or boot-mounted. While there is no right or wrong on the mounting style, ensuring the utmost convenience is the deciding factor, hence, it all boils down to the personal taste of the diver. Remember, though, that the above mentioned scuba dive computer reviews are wrist-mounted, thereby called as the best diver watches.

Wrist Dive Computer Versus Console Dive Computer

Wrist Dive Computer – There are several advantages of the dive computer watch over the console dive computer. Hence, the wrist dive computers are more preferred by thousands of diving enthusiasts worldwide.

  • More popular than the console dive computer
  • Looks like large watches, making them very handy and travel-friendly
  • Provides critical information at a glance
  • May be used as an everyday device, not just limited to diving
  • Can be mounted in a console
  • Easier to read while underwater
  • Some models come in rectangular shapes, offering larger display screens

Console Dive Computer – The console dive computers are the cheap dive computers, compared to the wrist dive computer variety. Here are the details to learn about the console dive computer.

  • Attached to the equipment through a hose
  • Typically comes with a pressure gauge
  • Readouts are normally larger than the wrist dive computer offers

Back Lighting

The back lighting is another feature to watch out for in the most popular dive watches. The back lighting is a feature that allows the diver to see the computer’s display without the need for a flashlight. Many divers cannot do without this option in their devices, achieving the utmost convenience from such diving gears.

Conclusion

In a nutshell, learning about the best rated computers is very crucial throughout the search for this device, allowing you to compare the dive computer ratings without the guessing work. Keep in mind the essential features and options that such diving gear offers, including its accuracy of recording the bottom time and the minutes left at a certain depth. It should also allow you to achieve the optimum amount of time from your dive.

Learning how to use a dive watch is the very step, before appreciating the value of every dive computer. Overall, this diving gear must be capable of ending up the probability of decompression sickness, which is the main problem of many divers. Thus, the accuracy of information that a dive computer provides must be highly reliable, especially during medical emergencies.

And with the unlimited options on the market, it is always a good idea to do your homework – careful research and comparison between the top 10 dive computers from reliable manufacturers, without disregarding your diving scenarios. Instead of considering the cool look of this diving gear, it is more sensible to pay attention to the helpful features and options.

Remember that the best dive watch for the money ranges from the basic to the inexpensive, up to the most sophisticated diving gear. But, knowing what you really need out of this diving gear, based on your experience level and available budget, while relying on a trusted brand is equally helpful to arrive at the best dive computer, in spite the limitless options on the market.
