Is the Garmin Fenix 8 suitable for diving activities?

The leakproof metal buttons ensure reliable operation underwater, whilst the watch tracks diving metrics including depth, time and ascent rate.

What makes the display different from other Garmin watches?

The 1.4-inch AMOLED display provides superior brightness and colour reproduction compared to traditional LCD screens. Protected by scratch-resistant sapphire crystal glass, it remains clearly visible in direct sunlight and offers always-on functionality without significant battery drain. The AMOLED technology delivers sharper text and more detailed map displays for better outdoor navigation.

How accurate is the GPS tracking on this model?

The multi-band GPS with SatIQ technology provides exceptional positioning accuracy by accessing multiple satellite frequencies simultaneously. SatIQ automatically selects the optimal satellite configuration for your environment, ensuring reliable tracking in challenging conditions like dense forests or urban areas. This results in more precise distance, pace and route tracking compared to single-band GPS systems.

Can I make phone calls directly from the watch?

Yes, the built-in speaker and microphone allow you to make and receive phone calls when paired with a compatible smartphone.

This hands-free functionality proves particularly useful during workouts or when your phone isn't easily accessible.
