Dive Computers 2023: Making Sense of Tech Underwater

Dive computers have revolutionized the diving experience, providing invaluable real-time data to ensure safety and enhance enjoyment. Given the plethora of models vying for your attention, it's no wonder this piece of gear often leads to a flurry of inquiries. Whether you're a seasoned diver or a newbie gearing up, understanding dive computers can make your underwater adventures seamless.


Types of Dive Computers

Dive computers cater to various preferences and diving habits. Broadly, they can be categorized into three types:

  1. Console/Gauge Mount Computers: Units like the Genesis resource pro snugly fit into your gauge console, providing a consolidated data point. Being attached to your regulator set ensures you won't accidentally leave it behind. New Zealand divers often favor this type, minimizing the risk of snagging when hunting for crayfish.

  2. 'Puck' Style Wrist Computers: Essentially, this design integrates a console-type computer into a wrist mount. The genesis resource pro and Scubapro Aladin Tec 2G are notable examples. Resembling a chunky wristwatch, this style allows divers to effortlessly monitor depth and time, ensuring a more streamlined SPG console.

  3. Wristwatch Style Computers: Sleek and compact, models like the Scubapro Meridian and Mares Matrix blend aesthetics with functionality. Perfect for those frequenting deep-blue waters or professionals who prefer not to remove their computers after a dive.

Feature Frenzy: What's Inside?

From basic time and depth readings to sophisticated gas switching capabilities, dive computers offer an impressive range of features:

  • Essential Metrics: Dive time, depth, and temperature readings.

  • Gas Management: Especially relevant if you're considering Nitrox diving or transitioning into technical diving realms requiring multiple gas decompression.

  • Power Management: User-replaceable batteries are perfect for occasional divers, while regular divers might prefer rechargeable options.

  • Safety Stop Reminders: Essential for ensuring safe ascents.

  • Digital Compass: For ease in navigation underwater.

  • Connectivity: Some models offer sync capabilities with smartphones or dive software for logging and analysis.

When purchasing, align your choice with your current and anticipated diving activities. Remember, investing in a slightly pricier model that aligns with your future aspirations can be more cost-effective than frequently upgrading.


Dive Algorithms: The Brain Behind the Device

Dive computers rely on algorithms – these are sets of logical instructions guiding the device in calculating essential metrics like no-decompression limits. Various manufacturers either license renowned algorithms or develop proprietary ones.

However, as divers may note, two people on the same dive but with different computers might receive slightly varying data. This is due to the differences in algorithms.

It's essential to recognize the extensive research and expertise backing these algorithms, aiming to minimize decompression sickness (DCS) risks. But as science continues unraveling the mysteries of DCS, remember that no system guarantees 100% safety.


Choosing the Right Dive Computer

Our diving experiences and preferences evolve, and your dive computer should be adaptable enough to cater to that growth. Consider not just your current needs but where your diving journey might take you.

Still puzzled? The underwater world is vast and mysterious, but the realm of dive computers doesn't have to be. Feel free to reach out to us with any queries.
