Mares Quad 2 Smart Wrist Underwater Scuba Dive Computer |

Product Overview

The Mares Quad 2 Smart Wrist Underwater Scuba Dive Computer is built for divers who rely on accurate, real-time data and demand flexibility across a range of underwater activities. Whether you’re exploring coral reefs on a recreational dive, planning multi-level technical descents, or timing freedives and spearfishing excursions, this wrist-mounted dive computer delivers consistent performance with professional-grade features. Engineered around the trusted Bühlmann ZH-L16C decompression algorithm, the Quad 2 gives divers the ability to customize gradient factors and ceiling-based stops, offering a tailored approach to safety and dive planning. Its rugged construction and intuitive underwater menu system ensure reliable operation in demanding environments, while the vibrant orange color enhances visibility in low-light or murky conditions.

Key Features

• Customizable Decompression Algorithm – At its core, the Quad 2 uses the Bühlmann ZH-L16C algorithm, enhanced with adjustable gradient factors. This allows experienced divers to fine-tune decompression profiles based on personal physiology, dive history, and environmental conditions. By setting conservative or more aggressive gradient factors, users can influence decompression stop durations and optimize safety margins during repetitive or deep dives.
• Multiple Dive Modes – The device supports air, nitrox, trimix, and bottom timer modes, making it adaptable for everything from shallow snorkeling trips to complex technical dives. The bottom timer mode is especially useful for non-decompression activities such as spearfishing or freediving, featuring a resettable average depth function and stopwatch to monitor performance without decompression calculations.
• Clear Segmented Display – The segmented LCD screen utilizes chip-on-glass technology, delivering high contrast and sharp visibility even in dim underwater lighting. Critical information—including current depth, dive time, decompression status, and gas mix—is organized in a structured layout, allowing for quick, at-a-glance interpretation during fast-changing dive conditions.
• Underwater Menu & Four-Button Interface – Divers can adjust key settings without surfacing thanks to the intuitive four-button control system. The underwater menu provides access to gas switches, mode changes, and safety functions, all navigable through streamlined quick commands. This hands-on control minimizes distractions and keeps focus on the dive.
• Time To Reserve (TTR) Monitoring – The TTR feature calculates remaining bottom time based on current depth and estimated air consumption, helping divers manage their gas supply proactively. This is particularly valuable during deep or extended dives where efficient air use is critical to safety and dive success.
• Integrated Dive Planner & Logbook – The built-in decompression dive planner supports repetitive dives with user-adjustable surface intervals, allowing for better planning over multiple days. The internal logbook records up to 100 hours of detailed dive data—including depth, time, temperature, and gas usage—providing a comprehensive record for review or certification purposes.
• Bluetooth Connectivity – Seamlessly pairs with the Mares smartphone app via Bluetooth, enabling real-time dive insights, automatic data syncing, and easy firmware updates. Post-dive analysis becomes more accessible, allowing divers to review profiles, track progress, and share experiences with training partners or dive communities.

Benefits & Use Cases

The Mares Quad 2 is a versatile tool suited for a wide spectrum of underwater pursuits. Recreational divers will appreciate its ease of use and reliable decompression tracking, while technical divers benefit from trimix support and customizable algorithm settings. Freedivers and spearfishers gain value from the bottom timer mode, which logs dive duration and average depth without decompression obligations—ideal for training sessions or competitive preparation. Snorkelers exploring deeper drop-offs can use the device to monitor time and depth, enhancing safety during extended surface swims. The TTR function supports efficient gas management, especially on deep or multi-level dives, while the adjustable surface intervals in the dive planner help those planning back-to-back dives over several days. With Bluetooth connectivity, users can transfer dive logs to their smartphone for detailed analysis, share data with instructors, or keep a digital record for certification. Whether you’re a weekend explorer or a seasoned technical diver, the Quad 2 adapts to your needs with precision and reliability.

Important Notes

Always consult a certified diving instructor or dive professional before using advanced features such as trimix blending or decompression planning. These functions require proper training and understanding to ensure safe diving practices. Regular firmware updates via the Mares app are recommended to maintain optimal performance, safety features, and compatibility with new software tools. After each dive, rinse the device thoroughly with fresh water to remove salt, sand, and debris, preserving its functionality and longevity. The package includes the dive computer only; additional accessories such as charging cables or replacement straps are not specified in the original product details.
