Mares Puck Pro Dive Computer Review


  • Modes and Functions: Air, nitrox, and gauge mode. The Puck Pro also has a watch, date and temperature functions.
  • Mares-Wienke RGBM algorithm: With optional deep stop mode and ability to adjust it to a more conservative setting.
  • Audible and Visual Alarms: You can turn the audible alarms on/off. The only disappointment here is that the Puck Pro lacks a depth alarm.
  • Plan Mode: This is where you plan your dive. The computer takes into account your previous dive data.
  • Dive Site Selection: Manually select your diving site, whether freshwater or saltwater.
  • Altitude Settings: This allows you to set altitude manually up to 3,700 meters (12,100 feet).
  • Imperial and Metric Units: You can select the unit system you’re comfortable with (meters and Cº, or feet and Fº).
  • One Button Control: Simple and intuitive. It makes setup and navigation of Mares Puck dive computers a breeze.
  • Backlighting: On night dives and in low light conditions, the screen lights up for visibility in the dark. 
  • Mineral Glass Display: This is better quality than the acrylic glass most budget computers usually feature. Mineral glass is highly resistant to scratches and enhances readability.
  • Dive Log: Keeps detailed records of your dives. You cannot manually delete old records. They age out and new ones are added.
  • USB Connectivity: Interfaces with a computer via a USB cable (sold separately) to download dive logs to a computer and update the firmware to access the latest upgrades by Mares.

User Experience


Set-Up: In surface mode, you can change settings and plan your dives using the dive planner. One of the reasons the Puck Pro is such a popular computerized wrist dive watch<span style=”font-weight: 400;”> is its simplicity and user-friendliness. Whether it is your first dive computer or you’re using it as a backup, you will find it a pleasure to operate.

The Puck Pro has a one-button for everything interface. Before you try it, you might wonder how practical a single button interface is but you will be pleasantly surprised to discover just how intuitive it is and how easy it makes operation and navigation. Just push the button to scroll through the menu. Once you get to the menu you’re interested in, hold the button to make adjustments to your satisfaction. The button is large and well positioned so you can press it easily even when wearing thick dive gloves<span style=”font-weight: 400;”>.

Once you select the dive mode and set the parameters, they remain fixed. If you press the button while underwater, it will show you the average depth, maximum depth, bottom time, or turn on the backlight.

Diving: The Puck Pro is water activated. You can also switch on the pre-dive mode manually but it will only start calculating your dive once you submerge below 4 feet. It features a Mares-Wienke-based RGBM algorithm, which allows safety-conscious divers to choose a more conservative setting. The Puck Pro has multi-gas capabilities and supports gas switching so you can switch between gases during a dive.

When diving, it monitors the depth, dive time, temperature, and performs decompression calculations. It will alert you when you need a safety stop if you ascend too fast, go over the safe ppO2 limit, violate a decompression stop, if nitrogen saturation is 100%, and if the battery is running low. The only alert lacking is a depth alarm. In bottom time mode, it will give you the depth, dive time, and temperature.

During the ascent, it shows the ascent rate in feet/minute as well as in graphical format. The safety stop timer comes on between 10 and 18 feet while ascending. In post-dive mode, it displays the desaturation time, surface interval, and no-fly time.

Readability: With the large, high contrast screen and segment display, you won’t have a problem reading and understanding the displayed dive data whether you’re underwater or on the surface. If you normally wear reading glasses, you will find them clearly visible underwater even without glasses on. If you’re diving in dark waters, just press, hold, and release the button to turn on the backlight.

Durability: The quality of Mares Puck dive computers is renowned and the Puck Pro is well constructed. It should accompany you on your diving adventures for years. It is composed of a tempered mineral screen glass that is highly scratch and impact-resistant, a high-quality rubber strap, and a strong bezel and case.
