About this device

The Primary is the device we built because nothing else existed that did this right. GMRS voice for clear, licensed communication. Meshtastic LoRa mesh for encrypted off-grid coordination. GPS for position awareness. All in a single field-ready unit that works completely offline.

This is not a toy. It is not a scanner. It is a purpose-built resilience tool for people who take preparedness seriously.

Requires a GMRS license ($35 / 10 years, covers your entire family).
