Scubapro G2 Tek Wrist Unit Only

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 G2 Tek offers all of the features of the G2 dive computer but uses a Pure Gradient Factor algorithm (ZH-L16 GF) instead of the standard Bühlmann algorithm. Everything else is shared: the 2.2 in color TFT display at 320x240p, three-button control, full-tilt digital compass, 394 ft / 120 m depth rating, eight gas Trimix capability and optional hoseless air integration.

No. This listing is the wrist unit only, so no wireless transmitter is included. Hoseless air integration is optional on the G2 Tek and supports up to 11 Smart or Smart Pro transmitters, which are purchased separately. The box contains the G2 CPL wrist unit, bungee, arm strap axle, retractor loop, protection film, USB cable, manual and quick cards.

Not immediately. Freediving, Trimix, CCR and Sidemount are available modes on the G2 Tek but are disabled from the factory and must be activated before use. Scuba and Gauge modes are available as supplied. Activating the technical modes gives you access to the eight gas capability for 21 to 100% Nitrox and Trimix.

The G2 Tek connects by Bluetooth Low Energy to a phone or handheld device, and by the included USB cable to a computer running LogTRAK for PC or Mac. Internal memory is 485 MB, which holds about 1,000 hours of dive profiles, so you can log a long season of technical dives before transferring them.
