Genesis Graviton Watch Computer Full Color MIP Underwater Diving Computer

A dive computer tracks the actual depth and time profile you have dived and the tissue loading that follows from it, which is personal to you. A rented computer has no record of your recent diving, and swapping models each trip means relearning the display and menus when you should be focused on the dive. Owning one you know well is a genuine safety and comfort improvement.

No. A computer only tracks the profile of the diver actually wearing it, and even buddies who stay together do not follow identical depth and time profiles. Every diver needs their own computer, and passing one between divers or between dives is unsafe.

Conservatism settings make the computer's calculations more cautious, shortening allowed bottom times and adding margin beyond the base algorithm. Divers commonly add conservatism for factors such as cold, hard work, fatigue, or repetitive multi-day diving. How and when to adjust it is covered by your training and your computer's manual, so set it before you get in the water and follow what your computer tells you during the dive.

Broadly there are two types: user-replaceable batteries, often a coin cell that you or a shop swap along with resealing an o-ring, and sealed rechargeable batteries that charge from a cable or dock. Neither is universally better, as replaceable cells are convenient on remote trips while rechargeables avoid ever opening the case. Follow the manual exactly for any battery change, because an improperly seated o-ring or case is the usual cause of a flooded computer.

Yes, both change the picture, and both are governed by your training agency's guidance and your computer's instructions rather than any casual rule of thumb. Many computers have an altitude setting that must be configured before diving at elevation, and most display a no-fly or surface-interval countdown after a dive. Follow your computer and your training, and ask a dive professional or a dive-medicine specialist if you are unsure.

Rinse it in fresh water after every dive day, paying attention to the buttons and around any sensor openings where salt crystals form, and let it dry fully before storing. Keep it out of prolonged direct sun and extreme heat, and avoid pressing buttons while sand is on the case. Inspect the strap or bungee often, because a failed strap loses far more computers than a failed computer does.

A wrist computer is worn like a watch and read by raising your arm, while a console computer sits at the end of a hose with your other gauges. Air integration means the computer also displays cylinder pressure, either through a hose or from a wireless transmitter on the first stage, and often estimates remaining gas time. All of them run a decompression algorithm, so the real difference is where you read the information and how much of it you get.

The Graviton offers Scuba Dive, Free Dive, Nitrox Dive, and Gauge Only modes, plus a Watch Mode for everyday use and a Plan Mode for checking no-decompression limits before a dive. The Graviton uses the Buhlmann ZHL-16C algorithm with three adjustable conservative factor levels (CF1, CF2, CF3).

Twisting your wrist cycles the Graviton's display between Depth, Compass Heading, and Nitrogen Loading screens without pressing a button mid-dive. This lets you check your compass bearing or tissue loading while keeping your attention on your dive.

The Genesis Graviton's Nitrox Dive mode supports oxygen percentages set as high as 99%, letting you input your actual gas mix for the dive. Combined with the Buhlmann ZHL-16C algorithm and three conservative factor levels, it calculates no-decompression limits for the selected gas.

Yes, the Graviton logs dives for download through the Dive Story App on iOS and Android devices, giving you a full dive log outside the computer itself. The app works alongside the Graviton's built-in GPS dive site recognition and onboard settings.
