What Makes the Bundle Powerful

This bundle unites real-time GPS tracking with mesh communication in a matched pair. Trace acts as your “tag,” broadcasting location updates, while Trekker Bravo acts as the network relay, extending range and keeping your system connected. Together, they eliminate reliance on cellular networks, letting your team track assets, dogs, and personnel in remote environments. You get the combined strengths of high-accuracy GPS (20-40 ft) and the scalable redundancy and reach of mesh. The more devices you add, the stronger your network becomes.

Mount Trace to a dog or gear to broadcast location. Use Trekker Bravo to ensure that broadcast reaches your command node or handheld. Wherever your team ventures; wilderness, desert, or disaster zones; this bundle keeps you in sync without needing cell towers or monthly fees.
