If I’ve learned one thing from listening to the entire back catalog of the excellent podcast Real Survival Stories, it’s this: Whether you’re mountain biking Californian trails or kayaking the west coast of England, the proverbial, you know, can hit the fan really fast. When an adventure flips unexpectedly into an emergency situation, the one thing you definitely want is a way to summon rescue, even when you’re far from cell networks.

Until now, tapping into off-grid comms meant carrying a dedicated satellite messenger. But alongside competitors like Google and Apple, Garmin—makers of the best outdoor sports watches—have made it possible to have satellite safety back up strapped to your wrist 24/7. The new Garmin Fenix 8 Pro now packs Garmin’s inReach satellite communication smarts, including satellite-powered text messaging, location check-ins and Emergency SOS–a virtual flare that hails assistance via Garmin Response. Here’s how to use it.

What You Pay For

First off, you must know that the new Fenix 8 Pro is $200 more than the original Fenix 8. You also need an inReach subscription plan, which starts from $8 per month and rises to $50 per month for the top tier. Picking the right plan depends on how many messages you want to send and how much you plan to use the live tracking.

All inReach packages include the Emergency SOS and LTE services and require a 30-day commitment. Monthly subscriptions are available, and if your tracking or communication needs change, you can also move up or down tiers. For situations when you’re without your phone but still have network coverage, there’s also phone-free LTE calls, voice messages, text messages, and live tracking.

How to Set Up Satellite Comms

From setup to send, I put the new satellite and LTE tools to the test using the Fenix 8 Pro 51-millimeter AMOLED. You need:

• The Garmin Fenix 8 Pro
• A smartphone with Garmin Connect and Garmin Messenger apps installed
• A Garmin account (that you sign into on your phone and watch)
• A Garmin Messenger account, linked to your phone number
• An inReach/satellite service plan–a free trial can be activated during setup

The initial setup is a bit of a faff, involving multiple Garmin apps, creating an account within Garmin’s inReach platform, and lastly, deciphering which subs package you need. Still, the whole process took about 15 minutes and can be done on your phone and the watch. You’ll consider that time well invested if you find yourself stuck in a ravine, being circled by predators, in need of help.
