Garmin inReach® Mini 3 Compact Satellite Communicator
A rugged, pocket-size satellite communicator built for off-grid safety. Send two-way messages, share your location, and trigger interactive SOS beyond cell coverage (active satellite subscription required).
Our Take: inReach Mini 3 is the “always bring it” satellite communicator. It’s compact enough to live in a pocket or pack strap, but still delivers the essentials: two-way texting, location sharing, and an SOS lifeline when you’re out of cell range. If you want big safety capability in a small device, this is the sweet spot.
- Interactive SOS emergency support Trigger SOS to reach a 24/7 emergency response coordination center and communicate during the rescue process (subscription required).
- Two-way messaging beyond cell coverage Send and receive messages when you’re outside cell service using satellite connectivity (subscription required).

- Color touchscreen + buttons A compact 1.9" diagonal display with touchscreen interaction and physical controls for quick access in the field.
- Rugged, water-rated build IP67 water rating for dust protection and incidental water exposure; built for harsh weather and hard use.
- Tracking + location sharing Share your route progress and location updates with contacts so they can follow along (subscription required; app/phone may be needed for some sharing features).
