Mares Puck Pro Ultra Dive Computer – Air, Nitrox, Depth,

Product Overview

The Mares Puck Pro Ultra Dive Computer is a dependable, feature-focused dive computer built for recreational divers who value clarity, safety, and practical functionality underwater. Engineered to deliver essential dive information in real time, it supports both standard air and enriched air Nitrox diving, making it a flexible option for divers exploring a variety of underwater environments. The high-contrast display ensures critical data remains easy to read, whether you’re diving in bright tropical waters or deeper, dimly lit zones. Its intuitive interface minimizes distractions, allowing divers to focus on their surroundings while staying informed. From shallow reef exploration to multi-level dives, the Puck Pro Ultra provides consistent performance and reliable data. With a long-lasting user-replaceable battery and wireless Bluetooth connectivity, it integrates smoothly into both casual and frequent diving routines, offering convenience without compromising core functionality.

Key Features

• Enhanced Visibility – The high-contrast screen delivers sharp, legible dive data in all underwater lighting conditions. Whether you’re in bright sunlight or low visibility, essential information such as depth, time, and decompression status remains clear and easy to interpret, reducing eye strain and helping you stay focused on your dive.
• Versatile Gas Options – Compatible with single gas Nitrox mixtures from 21% to 50% oxygen, this computer allows recreational divers to adjust their breathing gas settings to match their dive plan. This flexibility supports safer nitrogen absorption management and can extend no-decompression limits when used with proper training and planning.
• Advanced Algorithm – Built on the Buhlmann ZH-L16C decompression algorithm with dual gradient factors, the Puck Pro Ultra provides accurate and conservative decompression calculations. This proven model is widely respected in the diving community for its reliability, particularly during multi-level or repetitive dives, helping reduce the risk of decompression sickness.
• Extended Battery Life – Powered by a user-replaceable CR 2450 battery, the computer delivers up to 100 dives per charge. This extended lifespan is ideal for frequent divers or those on extended dive trips, reducing the need for frequent battery changes and ensuring the device is always ready for use.
• Seamless Connectivity – Integrated Bluetooth technology enables wireless transfer of dive logs to compatible smartphones or tablets. Using Mares desktop or mobile applications, divers can easily review, analyze, and share their dive history, enhancing post-dive analysis and long-term record keeping.

Benefits & Use Cases

The Mares Puck Pro Ultra is designed for recreational divers seeking a straightforward, reliable dive computer that performs consistently in real-world conditions. Its high-contrast display is especially beneficial for divers who frequently transition between bright and low-light environments, ensuring critical data is always legible. The Nitrox compatibility makes it a practical upgrade for divers progressing beyond basic air diving, enabling safer and potentially longer dives when using enriched air with proper certification. The Buhlmann ZH-L16C algorithm appeals to those who prioritize conservative, science-based decompression modeling, offering peace of mind during repetitive or multi-level dives. With up to 100 dives per battery, it’s well-suited for dive enthusiasts who log many dives annually or travel to remote locations where battery access may be limited. The Bluetooth connectivity simplifies digital log management, making it easier to track progress, share experiences with instructors or dive buddies, or maintain detailed personal records over time.

Important Notes

This dive computer is intended for recreational diving only and supports single gas Nitrox use. It is not designed for technical diving, mixed-gas configurations, or rebreather use. After replacing the battery, ensure the compartment is properly sealed to maintain the device’s water resistance. To preserve long-term performance, rinse the computer with fresh water after each dive and store it in a cool, dry place away from direct sunlight. While Bluetooth enables convenient data transfer to smart devices, the computer operates independently during dives and does not require a connected device to function. Always follow manufacturer guidelines for maintenance and use, and consult a certified instructor if you are new to Nitrox or decompression diving.
