Rheo Smart Dive Mask: The All-in-One Dive System

Critical dive data is presented outside of your field of view, so you never have to look down or shift focus. Instead of breaking awareness to check a wrist computer, everything stays in view, even in low visibility or fast-changing conditions.

Wireless Air Integration adds hoseless tank pressure monitoring directly to your heads-up display, keeping critical air data in view without adding gear.
Your critical dive data is in your peripheral vision without obstructing your view of the environment.

Rheo Smart Dive Mask combines your mask, dive computer, heads-up display, and compass into one streamlined system. That means less gear to pack, less drag in the water, and less setup before every dive. While traditional setups require divers to manage multiple devices, Rheo brings everything together in one intuitive system designed to make diving simpler from the moment you gear up.

Depth, NDL, tank pressure, and direction are always visible, powered by industry-standard air integration and support for advanced multi-gas dive profiles. With real-time data and alerts triggered at your defined thresholds, you no longer need to check gauges or calculate manually. You stay informed, react faster, and stay in control throughout the dive.

Rheo is built for practical, open dive use. It works with MH-8A air integration transmitters, supports multi-GNSS surface tracking, ships with pre-configured dive profiles, and lets you build custom displays in the RheoDive eDL app. Unlike systems built around add-ons or closed workflows, Rheo is designed as one integrated mask system.

Rheo Smart Dive Mask is designed for real-world dive schedules, delivering up to 25 dives per charge. The charging case not only protects your mask; it seamlessly recharges your mask between dives, so your gear is always ready when you are.

After years of recreational and professional diving, we kept encountering the same problem: every glance at a wrist computer meant losing focus on the environment around us. Inspired by the heads-up displays used in aviation, we created Rheo to bring critical dive data directly into view and make diving safer, simpler, and more intuitive.

A great dive mask starts with a great fit. Rheo uses multiple skirt sizes and a face-scanning feature in the RheoDive eDL app to help recommend the best option for your face shape before you dive. If your fit changes or you need a different size, the replaceable silicone skirt can be swapped without replacing the entire mask.

With the RheoDive eDL app, you can create personalized dive profiles for each phase of your dive, choose exactly what data to display, set alerts, and wirelessly sync everything to your mask before entering the water.

Unlike closed ecosystems, Rheo supports integration with third-party dive computers, so you never lose your dive history or control of your data. The app also includes free dive logging with no subscription required.

Integrated GNSS helps track surface position more accurately and improves dive logging after the dive. For group dives, professional operations, and recovery scenarios, that added location awareness creates another layer of safety and gives you more confidence before, during, and after every dive.

Rheo Smart Dive Mask is built for demanding dive conditions using durable, non-reactive materials and a robust frame design. If something gets damaged, you don’t need to replace the entire system. Key components like the skirt and lenses are designed to be replaceable, extending the life of your gear.
