f you train across multiple outdoor disciplines, you already know the routine: buying a dedicated walkie-talkie, an action camera, and a wind meter quickly turns into an expensive pile of single-purpose hardware. Motion Rivalry designed REACH to challenge that setup by putting modular accessories on a single base unit. The campaign raised over $122,000, and REACH is available for $359, representing a 40% discount off the $599 retail price.
At the core of the hardware sits a chassis. For positioning and balance tracking, a 10Hz multi-constellation GNSS locks position ten times a second, and a 200Hz 9-axis IMU tracks heading drift.
Swapping Add-ons
The physical setup changes depending on which module snaps into the top port. The Walkie-Talkie module works across 0.6 to 1.2 miles of line-of-sight range with multiple channels, while the Radar module uses 24GHz mmWave sensing to detect objects between 16 and 98 feet away across a 100-degree field of view.
The mechanism behind that swap is a single open-source connector at the top of the unit, accepting hardware modules in seconds.
For recording visuals and conditions, the Camera module records 1080p video at 60 frames per second from a rotatable, splash-resistant housing. When tracking environmental data, the Wind Meter module adds live wind speed readings down to 0.1 meters per second, along with humidity and temperature.
Display and Connectivity
The 3.5-inch display lays out speed, gradient, distance, and training stress score directly on the unit. For off-device analysis, the companion app on iOS and Android pairs over Bluetooth LE for route planning, reviewing a session, and Over-the-Air firmware updates.
Promising to replace several mature sports gadgets with a single modular body is an ambitious pitch, but whether users will consistently swap modules instead of grabbing dedicated tools remains to be proven on actual trails and water.
