Excellent watch, superb battery life, every feature I need for Running, Biking and Lifting. Love it !!!
I got the watch ahead of my hiking trip on the foothills trail in SC. I was able to get some maps of the trail downloaded and no few than a 1/2 mile on trail I got off track and the watch alerted me and that happened twice so it probably save me a mile or two of not walking back and retracing my steps and another plus was when my cell phones and Garmin inreach had no signal the watch had signal and I was able to get the weather report which was very much needed at the time. I’m not real tech savvy but it is simple enough for an old guy like me to make it work. Thanks again outdoor vitals….you guys are the best.Bob
Great watch for the price. It takes a little getting used to since I previously owned a Garmin 6x pro. The mapping function is much better than my Fenix 6x.
Will it work with my Inreach mini 2?
Does it have high resolution topical maps?
Yes, the Coros Apex 4 GPS watch features downloadable global landscape and topographic maps with street names, trail labels, contour lines, and points of interest. But No, the Coros Apex 4 GPS Watch cannot directly pair with or control a Garmin inReach Mini 2
Can you download the entire pCT trail Start to finish or do you have to download each state individually?
Yes—the full Pacific Crest Trail can generally be loaded as one route if it is available as a single GPX file, so you do not automatically need to download each state separately.
The practical limitation is the route file’s size and the watch model’s navigation/storage support. If the complete PCT GPX file is too large or will not sync, split it into sections—such as by state or segment—and load those individually. The watch follows a pre-loaded GPX route; it does not independently download the trail from COROS.
Typical process:
1. Obtain or export the PCT route as a GPX file.
2. In the COROS app, open Explore → + → Import Route.
3. Save the route, then sync it to the watch from the Device tab.
4. On the watch, choose a supported activity such as Hike, select Navigation, and choose the route.
Navigation support and map behavior vary by model by specific model. If you have any additional questions please reach out directly to Coros Customer Support as they will have the best and most current information on their products.
