Four 2-week agile sprints for hardware revision, software refinement, and performance tuning.
Keep your metrics always visible and your mind entirely present. Meet the world’s first patented smart dive mask with integrated HUD and GPS/GNSS surface tracking.
Rheo Dive is a mono-product brand with a singular mission: keeping divers safe and focused when it matters most. Through our patented smart dive mask, we deliver critical data via an unobtrusive HUD and offer ultimate surface safety with built-in GPS/GNSS tracking. We believe technology should enhance your awareness, not add to your task-loading.
Whether you’re a dive pro, technical diver, or underwater photographer, our goal is the same: deliver clarity and control through purposeful innovation. One product. One purpose. Designed to support sharper, more immersive, and more mindful dives.
Tanner Cheek is an Army veteran and former scout sniper with multiple deployments, holding a B.S. from Embry‑Riddle and an Executive MBA from Rochester. A licensed pilot and PADI‑certified diver, he developed a HUD‑equipped smart dive mask born of his experience in extreme environments, for divers who demand peak awareness, safety and performance.
Karlis is a deep-tech entrepreneur and engineer with 12+ years of experience taking hardware products from concept to mass production. With a background in robotics, consumer electronics, and high-performance systems, he leads Rheo Dive with a focus on bold design, real-world reliability, and breakthrough innovation in underwater technology.

RHEO Dive is the world’s first patented smart dive mask, engineered for clarity, control, and complete underwater focus. Its discreet HUD displays compass headings and critical dive telemetry—including depth, tank pressure, and NDL—just outside your direct line of sight, keeping you fully immersed without the task-loading of traditional gauges.
Designed for performance under pressure, it significantly reduces unnecessary movement and decision fatigue. On the surface, integrated GPS/GNSS tracks precise entry and exit points, adding a critical safety layer that allows surface support teams to rapidly locate a diver in an emergency. Currently field-tested by search and rescue professionals, RHEO is built for the world’s most critical underwater missions.
Made with durable, modular materials. Easily replace individual parts instead of buying a whole new mask to maximize lifespan and minimize waste.
Minimal, intuitive, and just outside your line of sight -the HUD delivers essential data without distraction.
Shaped by real-world divers. Feedback from our community drives every update and design decision.
Built-in GPS enhances surface tracking and safety, helping teams locate divers faster and more accurately.
