Garmin Fenix 8 Pro | Tactical GPS Smartwatch with Satellite & LTE Connectivity
- The Garmin Fenix 8 Pro is a huge upgrade, built as a true standalone device that works without your phone. Unlike the Fenix 7 Pro, which needs a phone nearby for smart features, the Fenix 8 Pro lets you call, text, and send a real SOS all on its own. It's the watch to wear when you're truly on your own and need a reliable connection.
- Make Calls and Send Texts No Phone Needed: The Fenix 8 Pro has a built-in speaker, microphone, and LTE connection. This means you can make and receive actual phone calls and messages directly from your wrist, a feature the Fenix 7 Pro does not have.
- Send a Real SOS from Anywhere on Earth: With built-in inReach satellite technology, you can send an SOS message for help to a 24/7 emergency center from anywhere, even with zero cell service. The Fenix 7 Pro's safety features can't do this; they only work when connected to your phone.
- Built Tough with a Long-Lasting Battery: The Fenix 8 Pro is built military-tough with a strong titanium bezel and a scratch-resistant sapphire lens. It also has a battery that lasts up to 27 days, giving you a rugged and reliable connection that works all by itself.

- There is no way for us to know how or if it was used once shipped, and we have to consider them unsafe until retested, inspected and certified.
- Exchanges and non-ballistic products do not have a re-certification cost.
