Garmin eTrex 20 Vs GPSMap 64

Do you need clarification about choosing between Garmin eTrex 20 and Garmin GPSMap 64? These two products are handheld GPS devices that many love because of their high performance and durability. Both products are popular choices for outdoor sports and trips. Nevertheless, you will find Garmin GPSMap 64 pricier than Garmin eTrex 20. So, what are the differences between these two models, and which one should you choose?


Garmin eTrex 20 comes with a simple design. It is small enough to allow convenient holding in a single hand, and the edges are rounded to ensure a comfortable grip. The buttons are put neatly on the sides to save space at angles the fingers can easily reach. Meanwhile, you can find a 2.2-inch transflective TFT display screen on the front surface.

The display has 240 x 320 resolution, generating a sharp and crisp visualization. On the other hand, Garmin GPSMap 64 comes with a rather bulky body. It doesn’t look elegant due to the fat and sturdy antenna on the top, but it is still slim enough to allow convenient one-handed operation. The buttons are put under the display screen.

Yet, the display only has 160 x 240 resolution. Thus, it doesn’t look as sharp. Garmin GPSMap 64 is also heavier than Garmin eTrex 20. Both models are weatherproof and able to withstand splashes and rain with their IPX7 rating. (Read also: Garmin eTrex 20 Vs. 30)


Both models are armed with GPS and GLONASS for the most precise and accurate, unmatched tracking performance. They also come with various mapping features, such as saving up to 200 routes and pinpointing essential locations on the map.

However, since Garmin GPSMap 64 has a slightly bigger internal memory, it can store more locations and log data. It can save up to 5000 waypoints or favorite places, as opposed to Garmin eTrex 20’s maximum of 2000. In addition, Garmin GPSMap 64 also features an internal buzzer that can notify you whenever vital information is on the device.

Anyhow, battery life is also an important aspect that we should pay attention to. Garmin GPSMap 64 only has a maximum battery life of 16 hours, while Garmin eTrex 20 offers up to 25 hours of continuous runtime per single charge.
