The Off-Grid Voice + Mesh Communication Duo for Teams

When voice matters and data is essential, the Spec5 Pulse Pack gives you both in one tight package. This bundle includes two rugged, field-ready radios that let your team speak directly via short-range voice, while meshing data across miles via LoRa. Whether you’re coordinating in remote terrain, managing a field mission, or simply staying connected without cell towers, Pulse Pack delivers seamless voice and text in a single system.

Each Spec5 Pulse unit supports two-way voice communication over FRS/UHF, while simultaneously functioning as a LoRa mesh node. Send text messages, share GPS locations, and maintain real-time team coordination, no infrastructure or cellular needed. With a durable PETG/ABS housing built for outdoor use and an 8-hour active battery life, Pulse stands up to long hours in demanding environments with confidence.

Who Is It For?

The Spec5 Pulse Pack is built for teams that demand voice and data connectivity in remote or infrastructure-less environments.

For tactical teams, it allows direct voice coordination while sharing GPS, routes, and alerts over mesh. For outdoor groups and expedition crews, it ensures you can speak and stay mapped even where cell towers vanish. For disaster response or remote operations, it’s a dual-purpose comm tool, voice when speaking is quicker, data when messages or location sharing are critical.

When every second counts and clarity matters, Pulse Pack keeps your squad talking, navigating, and meshing no compromises.
