Mares Dive Computers — From Compact Entry to Trimix-Capable Flagship

Mares' dive computer lineup spans an unusually wide range — from genuinely simple, single-button wrist computers through a full-color, Trimix-capable system supporting five simultaneous high-pressure gas probes. What ties the range together is Mares' BLUELINK Bluetooth ecosystem, letting most current models sync directly to a smartphone app for logbook review, firmware updates, and dive planning without cables.

At DiveCatalog.com, we carry the current Mares computer lineup as an authorized dealer.

The Mares Dive Computer Range

Puck 4 — Compact and Bluetooth-Enabled

The Puck 4 uses the Buhlmann ZH-L16C algorithm with adjustable gradient factors, supporting air and nitrox (EAN 21–99%) plus a bottom timer mode. Maximum depth rating of 150m (492ft), with a 100-dive logbook capacity. The chip-on-glass display with 800 segments and mineral glass cover prioritizes durability and clarity, and a user-replaceable CR2450 battery keeps maintenance simple. Integrated Bluetooth connects directly to the Mares or SSI app for logbook sync, dive plan updates, and firmware upgrades. Single-button operation and removable straps (including a bungee option) round out a genuinely accessible entry computer.

Puck Pro+ — The Evolution of the Puck Pro

The Puck Pro+ refines the original Puck Pro with an ultra-flat design for a better fit on the wrist. It handles multi-mix dives with up to two nitrox blends (21–99%), displayed across a clean three-line layout using a traditional segment display for clear readability. The logbook holds 35 hours of dive profile at a 5-second sampling rate, and the device supports depth gauge mode with resettable average depth and a built-in stopwatch. Upgradable firmware and a user-replaceable battery keep this an accessible, low-maintenance computer despite its capable feature set, and BLUELINK Bluetooth connectivity allows wireless data download to a smartphone.

Smart — Ergonomic Multimix and Freediving

The Smart pairs a clear, ergonomic display with multimix and freediving capability. On the surface, you can adjust nitrox settings and review the logbook; underwater, the interface prioritizes depth and decompression status, with depth shown on the top line and decompression data in the middle row. Side-mounted buttons keep the profile compact: the upper-right button cycles through max depth, average depth, and depth at gas use; the lower-right adjusts a secondary field for temperature, oxygen percentage, CNS, time of day, or stopwatch. A 4-second timeout automatically returns the display to dive time for safety. User-replaceable battery for ongoing low-maintenance use.

Genius — The Trimix-Capable Flagship

The Genius is Mares' top-tier dive computer, built for divers running genuinely demanding technical profiles. It manages Trimix and Nitrox dives with gas changes, using data from up to five high-pressure probes for integrated gas supply management that optimizes both bottom time and decompression based on remaining gas. The ZH-L16C decompression algorithm (16 tissue compartments) supports adjustable gradient factors, selectable deep stops, and differentiated ascent speed based on altitude — genuine control over the shape of your decompression curve. The 2.7-inch backlit, scratch-resistant tempered mineral glass display uses QVGA resolution (320×240, 256,000 colors) across three horizontal display zones, operable via four buttons accessible even with thick gloves. Oxygen range spans 6–99%, with predictive gas-change alerts as a switch depth approaches, and the computer can recalculate decompression in real time if a planned gas becomes unavailable mid-dive. The optional LED Tank Module pairs with the Genius for hose-less, color-coded tank pressure monitoring, EN250 certified to 300 bar.

Mission Puck 2 — Console Configuration

The Mission Puck 2 combines a dive computer and pressure gauge in a single console, with a chrome-plated brass gauge housing for durability. Supports air and nitrox 21–50%, with a 150m (492ft) depth rating and 35-hour logbook capacity at a 20-second logging interval. Single-button operation with an Easy Access system keeps key functions within reach, and multiple lanyard attachment points support flexible mounting.

Frequently Asked Questions — Mares Dive Computers

What is BLUELINK?

BLUELINK is Mares' Bluetooth clip connector system, allowing dive data recorded on compatible Mares computers to be downloaded directly to a smartphone without cables or connectors — a more streamlined way to record, review, and store your diving history.

What is the difference between the Puck 4 and Puck Pro+?

Both are compact, single-button computers. The Puck 4 uses the ZH-L16C algorithm with adjustable gradient factors and a 100-dive logbook capacity; the Puck Pro+ has an ultra-flat profile and a 35-hour profile-based logbook with multi-mix support for up to two nitrox blends. Both offer Bluetooth connectivity, but with slightly different feature emphasis.

What makes the Genius suitable for Trimix diving?

The Genius supports up to five high-pressure gas probes for integrated gas supply management, predictive gas-change alerts, real-time decompression recalculation if gas availability changes mid-dive, and an adjustable ZH-L16C algorithm with selectable deep stops — the full feature set serious technical and Trimix divers require.

Do Mares computers require a subscription for app connectivity?

No — the Mares and SSI apps used for BLUELINK syncing are free to use for logbook management, dive plan updates, and firmware upgrades.
