How does the Apple Watch Ultra 2 compare to the Garmin Epix Pro in terms of GPS accuracy

Apple Watch Ultra 2

The Apple Watch Ultra 2 features a dual-frequency, multi-constellation GPS/GNSS chipset, which enhances its ability to maintain accuracy in various environments. In general, it performs well, particularly in open areas. However, it has been noted that its accuracy can be compromised in challenging conditions such as near tall buildings or dense woodland. For instance, during tests, the Ultra 2 showed discrepancies of about 5 meters under these conditions, and some users reported it being off by as much as 0.4 miles during a 50-mile ultra run compared to the Garmin[1][2].

While the Ultra 2's dual-band capabilities allow for better tracking, there are instances where it rounds down distances and exhibits inaccuracies, especially when navigating tight turns or under heavy tree cover[1]. Despite these limitations, it generally maintains a good level of accuracy across most scenarios.

Garmin Epix Pro

The Garmin Epix Pro is also equipped with multi-band GPS technology and has a reputation for delivering reliable accuracy, particularly in demanding environments. In various tests, including ultra marathons and half marathons, the Epix Pro consistently provided readings that were closer to the actual distances than those recorded by the Apple Watch Ultra 2. For example, during a half marathon event, the Epix Pro reported distances that were much more aligned with the official course measurements compared to the Ultra 2, which tended to overestimate distances due to wider recorded paths[3][6].

Comparative Performance

Both devices are capable of excellent GPS performance; however, the Garmin Epix Pro tends to edge out the Apple Watch Ultra 2 in terms of overall accuracy in complex environments. Users have noted that while both watches perform similarly in open spaces, the Garmin's performance is generally superior when faced with obstacles like trees or buildings. This is evident from various user experiences where the Garmin maintained accuracy even under adverse conditions that challenged the Apple Watch's capabilities[2][4].

In summary, while both watches leverage advanced GPS technology to enhance tracking accuracy, the Garmin Epix Pro appears to provide more consistent and reliable performance compared to the Apple Watch Ultra 2, particularly in challenging environments.
