Engineered for expedition leaders, search & rescue units, alpine endurance athletes, and backcountry survivalists. Open-hardware beacon protocol designed to save lives where networks fail.
Combining low-frequency sub-GHz radio mesh, GNSS multi-constellation positioning, and long-range emergency ping alerts into zero-subscription hardware.
Relay route coordinates across team members without cellular towers. Our decentralized mesh architecture automatically hops data across mountain ridges and deep canyons.
