While the Garmin eTrex 20x isn’t fully waterproof (so we don’t recommend taking it for a spin), it’s no wimp in the rain, either. When cared for appropriately, the Garmin eTrex 20x can be taken out in light rain, making it a true all-weather GPS.

Alternative GPS Options

When buying a new GPS unit, it’s always worth checking out how a given product compares with other available options. When it comes to the Garmin eTrex 20x Hiking GPS, there are three main alternatives that you could choose from. Let’s take a look at how the eTrex 20x stacks up to its competitors:

Garmin eTrex 20x vs. Garmin GPSMAP 66st

The Garmin GPSMAP 66st is a super reliable and accurate GPS unit that’s loaded up with features for someone who puts precision in navigation above all else. The GPSMAP 66st connects quickly and reliably with satellites, has easy-to-use buttons, a big screen, and is capable of connecting with your smartphone to provide you with weather updates.

While all of this might sound grand, it’s important to note that these features come at a price. The Garmin GPSMAP 66st is, on average, $200 more expensive than the Garmin eTrex 20x. So any would-be purchaser of the device needs to take the time to reflect on whether or not these added features are worth it to them.

For many of us, these advanced features wouldn’t enhance our experience or our navigation abilities. So they probably aren’t worth the investment as well as the added weight and bulk. However, if you need and want a super high-powered GPS unit for precision navigation, the GPSMAP 66st might be worth a shot.

Garmin eTrex 20x vs. Garmin eTrex 10

When compared to the Garmin eTrex 20x, the eTrex 10 is an incredibly simple unit with very few features. Lightweight, affordable, and with the same great 25-hour battery life, the Garmin eTrex 10 is a less featured alternative to the eTrex 20x.

The Garmin eTrex 10 doesn’t have a color display or an expandable memory, so if you want these features, you’ll have to look elsewhere. But, at just 5 ounces and with an IPX7 waterproof rating, the eTrex is a small and durable alternative for people looking to keep things simple.

Plus, the eTrex 10 is, on average, $100 less expensive than the eTrex 20x, so if you’re looking to save some money, the eTrex 10 might be the way to go. On the other hand, if you want a durable GPS with some quality features, it’d be worth investing in the eTrex 20x.

Garmin eTrex 20x vs. Garmin inReach Explorer+

While the Garmin eTrex 20x is a quality handheld GPS unit, there’s one thing it can’t do: send and receive messages. Thankfully, the Garmin inReach Explorer+ offers the many of the same great GPS features as the eTrex 20x with some awesome satellite messaging capabilities.

A fully-featured GPS unit, the inReach Explorer+ can help you navigate effectively, while also having the added bonus of offering two-way messaging as well as an SOS feature for emergencies. Thanks to Garmin’s Iridium satellite messenger, the inReach Explorer+ can work anywhere in the world, allowing you to stay connected, wherever life takes you.

The inReach Explorer+ is much larger and heavier than the eTrex 20x. Plus, the inReach Explorer+ requires a monthly service plan to operate, so some might not want to shoulder that cost.

So, if you want messaging capabilities, the Garmin inReach Explorer+ combines the best of a GPS unit with a satellite communication device. But, if all you need is a GPS unit, the eTrex 20x might be the better option.

Customer Reviews

The Garmin eTrex 20x is one of the most popular handheld GPS units in Garmin’s line-up, so there’s no shortage of opinions on it in the outdoor world. Thus, we can use a lot of this information to help us decide whether or not the eTrex 20x is right for us.

For the most part, outdoor enthusiasts find that the eTrex 20x is an affordable GPS unit that’s both durable and reliable. However, many people suggest acquiring the extra customizable maps for the device as a GPS is only as useful for direct navigation purposes as the maps it’s loaded with.

That being said, some people do express frustration over how long it can take the device to sync and update through Garmin’s computer program. So be sure to leave plenty of time for this activity before you head out into the backcountry.

The Final Verdict

Ultimately, after our Garmin eTrex 20x review, we can conclude that the device is a reliable, durable, high-quality handheld GPS unit for everyday use. Whether you’re out on a bike ride around town, out for a day on the water, or exploring in the backcountry on an extended expedition, the eTrex 20x is a solid option for an affordable GPS with plenty of great features.
