Your smartphone or tablet built-in navigation machine may be perfect for casual usage, but you’re way better off using a proper GPS receiver if you’re concerned with outdoors sport A separate mapping interface offers certain benefits.

Typically they are much more weather-resistant and durable, for starters. Most devices use rechargeable battery so power loss is less of an issue. They usually often have far more advanced functions, which are useful for outdoor activities

A value GPS is an invaluable tool while you’re out and about in the nature. A GPS can help you instantly and easily identify the precise position in addition to the chart and compass. Give your new elevation and store potential use points.

But how do you pick only one handheld device for your diverse adventures? With so many many handheld GPS units out there. I recognize how challenging it is to include a GPS, so with this Garmin eTrex 20x review, I’m here to provide you with a detailed view of one fantastic GPS device.

Upon arrival, we’ll have a peek at some of the wonderful features the Garmin eTrex 20x has to bring. We can talk about who is right for the Garmin eTrex 20x and what people just have tell about the unit.

Overview of etrex 20x reviews

You want to get a solid, GPS without a Gamin eTrex 20x, with the whistles and whistles that push the price higher. Although the unit is just 5.1 ounces, the memory of this device is 3.7 GB and it holds 2.00 routes and 200 routes. It comes with a simple map such as all Garmin units, but it can upload more accurate topographical maps. With 25 hours of battery life, the eTrex 20x has earned our Best Buy Award, light, fast and accurate. We think it is a good option if you want a cheap GPS device that fits a ton into a few.

I get around 22-24 hours depending on my backlight and the amount that I use for regular alkaline AA batteries. When I was in the canyons, when I needed to work harder to close the signal, the smaller amount appeared to be. Carry in your bag a few additional AA batteries and call them a day. The eTrex 20 was running for an incredible 23 hours 29 minutes with the backlight off. The 50 hours were spent on my “natural” walk with a better view and better life, Turn off GLONASS, WAAS, to optimize battery life.


Only the capacity to run GLONASS and GPS satellites is one thing in the latest eTrex series that is absent from all other Garmin units. GPS is available only, but GLONASS does not have any preference only. GLONASS improves precision theoretically. In the north and in the urban (and natural) canyons, this is particularly so.


The eTrex 20, GPSMAP 60CSx and GPSMAP 62s installed on my mountain bikes controls were used to measure the precision with tracklog. Every five seconds, all units were set to track points. Tracks on and return runs were compiled, and track splitting errors examined afterwards. The concept here is that the registered track on the way out could preferably fit that recorded on the way back to the trailway. No unit really achieves the ideal, of course.

The 60CSx worked best, generally with less bug fixes and a median distance error of around 80.” The 62s had considerably more parts, easy to see, and maxed out to around 120.” The eTrex was the worse with more noticeable faults, which appeared to be more distant, with a maximum gap of about 125.’ I find it curious, although not shocking, that most advanced firmware is the oldest model, while the latest device is the worst with the least developed firmware. Here is an illustration of a track eTrex 20 (you might press it for a larger picture)…

Customize Maps

The Garmin eTrex 20x enables users to import their maps for an improved navigation systems experience if land-based topo maps just aren’t enough for their journey. The interface enables you to input pre-charged memory cards with an additional collection of maps with an eTrex 20x MicroSD card slot and3.7 GB of memory.

Garmin offers a range of microSD map packs, including urban commuting, coastal navigation and topographical charts. And the BirdsEye satellite imaging device can be used by Garmin. This helps you to import and embed satellite imagery into your chart for additional detail.

Ease of Use

There’s no Garmin 20x touch panel. It is a GPS device with simple map and guidance functions. We find we cannot depend entirely on the chart for point-to-point navigation. The back cover is modeled with a spine compliant with assembly devices. The buttoned configuration allows it simple to start and off labeling a way point with thin or thick with thick or thick.

The base map includes only detail about path (not trail). We enjoyed quick battery access and the simple-to-use remote device to switch off and on.


The GPS series eTrex is the smallest system we’ve reviewed — the 20x panel is just 2.2inches long. The backlight is always quick to switch and interpret in the immediate sunshine, and is weak enough not to blind us at night.

The eTrex 20x comes with a lifetime and crisp view of 25 hours. We found it very easy to learn, but a touchscreen eTrex model could be for you if you want a larger view. But it is important to take into account that other versions with bigger displays still have a higher price.


While several others have tackled various other topics, this device covers it fairly well as far as GPS functionality is concerned. There are not many (or even no) whistles, but most of the others are hidden by a handset, which we used to take anywhere. We’d like to get a barometer altimeter and a compass mechanical, but we find it very helpful.

We find it very simple to throw in a bag with us skiing, riding, hiking and fishing because it is so lightweight, compact and sturdy. Controls are fast, batteries last long and we can easily use them whether they are wet, cold or dark. Few of the features, like texting, take a little longer and the absence of a barometric altimeter reduces the precision of some of the altitude readings, but we think that this unit could be used almost everywhere.


For daily usage, Garmin eTrex is a secure, long-lasting, high-quality, manual GPS device. Even when it is cold, the batteries last considerably long, and especially if two lithium batteries are put into the device. It is helpful to couple with a tablet, in particular if circumstances find it difficult to use a smartphone. If you are cycling around the area, on the lake for a day or on a long expedition in the backcountry, eT Rex is a good one.
