GPS accuracy - Fenix 7X vs Enduro 3

The two screenshots above are from two trail runs on exactly the same trail a few days apart - the first one with Fenix 7X, the second one - Enduro 3.

What you see is the offset to left side relative to the direction of run. My estimate is that the offset is about 5 meters (15 feet) each way, so 10 meters between the out and back tracks. The same effect can be observed throughout the entire run, but here it is the most pronounced.

I remember Fenix 6X having the same issue. Fenix 6 has an older Sony GNSS chipset. Enduro 3 has a newer Sony chipset, so that is common. Fenix 7 has a Mediatek Arioha GNSS chipset.

Has anyone observed a similar issue? Consistent 5 meter offset is pretty bad for a watch released in 2024 if you ask me. It is supposed to be within 2-3 meters 95% of the time as you see on the track produced by Fenix 7X.

My Enduro shows 16.13 km and my other watch 16.05 km

That's a deviation of 0.5%, it means actually very accurate. You'd struggle to get such accuracy even from many professional devices.…

If i remember correctly even the Fenix 8 have the same issue with the GPS.

For me it's not a deal breaker, but i have seen alot of threads about this issue so it should be a priority to Garmin also.…

I am sorry to hear you are having this issue. For best GPS results we would recommend trying a few initial steps.

Ensure the watch software is on the latest version.
Even when up to date, it is important to sync with Garmin Express or the Connect app often. This ensures the prediction satellite data is up to date.
Be sure you are using the best settings for accuracy. (Be aware, accuracy and battery life are a balance. The more accurate settings will use more battery life.) We would recommend the following:
- Satellites: All+Multiband
- 3D Speed: On
- 3D Distance: On
- Auto Pause: Off
- Data Recording: Every Second

It is important to bear in mind, that even in perfect conditions GPS will have a margin on error on any Garmin GPS device. Things such as environmental factors and standing still can cause larger accuracy errors.
