Product Overview
The Mares Quad Ci Wrist Dive Computer (Black/Silver) is engineered for divers who need advanced functionality without compromising on reliability or ease of use. Designed to perform at depths up to 150 meters, this wrist-mounted dive computer supports both recreational and technical diving applications. With multiple dive modes, real-time data monitoring, and smart connectivity features, the Quad Ci adapts seamlessly to a wide range of underwater environments and diving styles. Its rugged construction and intuitive interface make it a dependable companion for everything from shallow reef dives to complex technical expeditions. Whether you’re tracking gas mixtures during a trimix dive or navigating with precision using the built-in compass, this device delivers accurate, real-time feedback when it matters most.
Key Features
- Customizable Bühlmann ZH-L16C Algorithm – The heart of the Quad Ci’s decompression system is the Bühlmann ZH-L16C algorithm, which allows divers to fine-tune gradient factors. This customization enables more personalized dive profiles based on individual physiology, dive history, and comfort level, enhancing both safety and dive flexibility.
- Multiple Dive Modes (Air, Nitrox, Trimix) – The computer supports air, nitrox (EAN from 21% to 99%), and both hypoxic and normoxic trimix diving. This versatility makes it suitable for technical divers who require precise gas management across varying depths and dive profiles.
- High-Resolution 8-Color MIP Display – The Memory in Pixel (MIP) color display offers excellent visibility in all lighting conditions, including direct sunlight. Its eight-color capability allows for intuitive data interpretation, with color-coded alerts and clear graphical representations of critical dive information.
- Integrated Digital Compass & Stopwatch – A full-tilt digital compass aids in underwater navigation, helping divers maintain course and locate points of interest. The built-in stopwatch supports accurate timing for bottom time, safety stops, and ascent rates, contributing to safer dive practices.
- Hoseless Tank Data Integration – The Quad Ci can connect wirelessly to up to five transmitters, allowing real-time monitoring of tank pressure and gas saturation. Color-coded indicators provide instant visual feedback on air supply status, improving situational awareness and reducing reliance on manual checks.
- Bluetooth Connectivity & Mares App Integration – Using Bluetooth, divers can sync dive logs, receive firmware updates, and analyze dive data through the Mares app. The system supports up to 20 hours of dive time per charge and is rated for up to 500 recharge cycles, ensuring long-term reliability.
- Extended Memory & Sampling Rate – With the ability to log over 100 hours of dive time and a 5-second profile sampling rate, the Quad Ci captures detailed dive data for thorough post-dive analysis. This high-resolution logging supports better planning and review of dive performance.

Important Notes
This dive computer is suitable for both freshwater and saltwater diving. To maintain optimal performance, users should follow manufacturer recommendations for battery care, firmware updates, and regular equipment checks. While the device supports trimix diving, proper training and gas blending procedures are essential for safe use. Wireless transmitters required for hoseless tank monitoring are sold separately and must be compatible with the Mares system. Regular pressure testing and maintenance of all connected gear are strongly advised to ensure safety and accuracy during dives.
