The Garmin eTrex 20x is your best bet for a dedicated, outdoor ready hiking GPS. There are more expensive models, and smartphone alternatives, but for a lot of hikers, the eTrex 20x will give you the best bang for the buck. Here’s why I recommend it.
The eTrex 20x is a small, outdoor ready mapping GPS unit. You can follow a pre-made track or route, or navigate to a waypoint. Or you can navigate by looking at the loaded maps on the small color screen. It’s waterproof, rugged, and outdoor ready (so unlike most phones, you can drop it without shattering the screen).
If you read the reviews for the eTrex 20x (especially on Amazon), you’ll see that many people give it low stars and complain about the maps. Garmin’s marketing makes it seem like you can start mapping hikes out of the box with this thing, and it’s not true.
Garmin includes a base map, which will basically tell you what city you’re in and what interstate is close to you. It’s pretty worthless, BUT BUT BUT you can get free topographic maps and load them on the unit very easily. No need to buy expensive Garmin maps. And Garmin provides a free program called Basecamp (Windows and Mac) that’s a great tool for planning routes and loading them onto the unit. I use it all the time.
