Mares Puck 4 Wrist Dive Computer | Entry-Level Watch-Style

Product Overview

The Mares Puck 4 Wrist Dive Computer is an entry-level, watch-style dive computer designed for recreational and technical divers who value simplicity, reliability, and advanced functionality in a compact form. Built for underwater use, it combines essential dive tracking with customizable decompression planning in a rugged, easy-to-wear design. Its single-button control system makes operation intuitive, even with gloves on, while the clear display ensures critical data is always visible. Ideal for divers progressing beyond basic models, the Puck 4 supports multigas configurations and integrates seamlessly with digital logging via Bluetooth. Whether you’re exploring coral reefs or planning deeper decompression dives, this dive computer delivers the tools you need with minimal complexity.

Key Features

• Customizable Dive Algorithm – Utilizes the Bühlmann ZH-L16C decompression algorithm with adjustable gradient factors, allowing divers to fine-tune decompression calculations based on personal preference or dive conditions. This flexibility enhances safety and precision, especially during complex or repetitive dives. By adjusting gradient factors, users can tailor ascent rates and safety stops to match their comfort level or specific dive profiles, offering a personalized approach to dive planning.
• Versatile Multigas Support – Compatible with up to three gas mixes including air and nitrox, and includes a bottom timer mode. This makes the Puck 4 suitable for both recreational and technical diving applications, giving advanced divers the ability to switch gases during a dive without changing equipment. Whether you’re doing a simple air dive or managing multiple nitrox blends on a technical descent, the computer adapts to your gas strategy in real time.
• Crystal-Clear Segment Display – Features an advanced chip-on-glass (COG) segment display that delivers sharp, high-contrast readability even in low-light underwater environments. Critical dive data such as depth, time, and decompression status are clearly presented for quick reference. The display remains legible at various angles and lighting conditions, reducing eye strain and ensuring you can focus on your surroundings.
• One-Button Interface – Simplifies navigation through menus and settings with a single-button control system. This design reduces clutter and minimizes the chance of accidental input, making it ideal for divers who prefer straightforward operation without sacrificing functionality. Despite its simplicity, the interface provides full access to dive modes, settings, and logbook functions with minimal effort.
• Integrated Bluetooth Connectivity – Enables wireless transfer of dive data to a smartphone or tablet using the Mares app. Divers can review logs, analyze performance, and share dive details without needing additional cables or adapters. The app allows for easy organization of dive history, tracking of progress over time, and integration with digital dive logs for personal or instructional use.
• Practical Dive Tools – Includes a decompression dive planner for pre-dive planning, a digital logbook to store dive history, and a resettable average depth tracker. These features support better dive management and post-dive review. The planner helps visualize no-decompression limits and gas switches before entering the water, while the logbook stores essential data from each dive for future reference.
