Mares Puck 4 Wrist Dive Computer — Black/Olive

A single-button computer for air and nitrox diving

The Mares Puck 4 combines a segmented display, a single-button interface and Bluetooth in a wrist-mounted dive computer. It runs the Bühlmann ZH-L16C decompression algorithm with adjustable gradient factors. The selected version is Black/Olive.

Who this suits

Its appeal is a straightforward control layout for divers who want air and nitrox functions without a multi-button watch-style interface. The single button is the main interaction choice: consider how you prefer to move through menus before choosing a computer. A bottom-timer mode is also available alongside Air and Nitrox.

A segmented display for the information that matters

The display uses more than 800 segments. That is a segmented presentation of dive information, rather than a full-color image-based screen. Check how comfortably you can read the character layout when comparing it with other computers.

Algorithm settings and dive planning

Adjustable gradient factors allow the Bühlmann calculation to be configured. Treat those settings as part of your trained planning process, not as a generic safety slider or an instruction to select particular numbers from a shopping page. A decompression planner is also listed, giving the Puck 4 a role before the dive as well as underwater.

Battery and log management

The CR2450 battery is user replaceable, while Bluetooth provides a wireless connection for working with dive records. A built-in digital logbook stores dive records. The combination gives you a replaceable power source and wireless log management.

Choose this version for its controls and mode set

The Puck 4 makes sense to consider when air/nitrox operation, a single control button and a replaceable battery are the priorities. Match the Black/Olive color and Puck 4 name when comparing listings. A similarly named computer or a different bundle should not be treated as this exact version.
