Does REI San Diego offer classes or private sessions on how to use Garmin "In Reach?"
Or are there other ways to learn how to use this device?
@Jha Thanks for reaching out!
While we don't currently offer classes on the Garmin inReach, we do have navigation courses that have resumed in some selected areas. If you aren't familiar with navigating with a map and compass we highly recommend taking one of those classes. You can find availability in your area at our REI Classes & Events page. Not only can it provide knowledge that is directly applicable to the backcountry, but it lays the groundwork of skills for using and understanding a GPS.
In terms of the Garmin inReach specifically, there are a couple of options for getting better acquainted:
Additionally, we recommend tacking a look at the library of inReach videos on Garmin's website. The can give you a lot of insight into the device and how it works.
Hopefully this helps, thanks!
