Built with a focus on usability, it offers essential dive tracking and safety features in a sleek, wearable design that fits comfortably on the wrist. Whether you’re exploring coral reefs or advancing your technical diving skills, the Puck 4 delivers critical dive data with clarity and precision. Its intuitive one-button control system makes it ideal for divers who prefer straightforward operation without sacrificing performance. This dive computer balances essential safety features with modern connectivity, making it a practical choice for both new and experienced divers.

Key Features

• Customizable Dive Algorithm – The Puck 4 uses the Bühlmann ZH-L16C decompression algorithm with adjustable gradient factors, giving you the ability to fine-tune decompression calculations based on personal preference or dive conditions. This feature enhances safety during deeper or multi-level dives by allowing more conservative or liberal settings depending on your experience and comfort level.
• Versatile Multigas Support – Capable of handling up to three different gas mixes—including air and nitrox—the Puck 4 adapts to a wide range of dive profiles. This makes it suitable not only for recreational diving but also for technical divers who switch gases during a dive. The bottom timer mode adds flexibility for training or non-decompression dives where precise timing is essential.
• Clear Segment Display with Chip-on-Glass Technology – The advanced display ensures high visibility in all underwater conditions, from bright tropical waters to low-light environments. Information such as depth, dive time, no-decompression limits, and ascent rate is presented in a clean, segmented layout that’s easy to read at a glance, reducing cognitive load during critical moments.
• Simple One-Button Interface – Navigation is streamlined with a single-button control system, minimizing complexity and allowing quick access to functions like the decompression planner, digital logbook, and average depth tracking. This design reduces the learning curve for new users while maintaining efficiency for seasoned divers.
• Integrated Bluetooth Connectivity – Seamlessly sync your dive logs to the Mares app via Bluetooth, enabling easy data transfer for post-dive review, sharing, or long-term tracking. This feature simplifies logbook management and supports dive planning by providing access to historical data and trends.

Whether used for shore dives, boat excursions, or training sessions, the Puck 4 provides reliable performance across a variety of underwater environments.

Important Notes

Always ensure the dive computer is properly calibrated and updated before use. While the Puck 4 supports multigas functionality, users should receive proper training in gas switching procedures before attempting technical dives. The device is designed for underwater use and should be rinsed with fresh water after each dive to maintain longevity. Data transfer requires the Mares app, which is compatible with most modern smartphones. This product does not include a charging cable or additional straps unless specified in the package contents.
