For a small, low-cost GPS receiver, you really can’t beat the Garmin eTrex. There are several models in the eTrex series. In this product review, I will discuss the basic model; often referred to as the "Yellow eTrex." If you like the design and feel of the eTrex, but require a more powerful and feature-rich unit, you will have to upgrade from the basic model.
Garmin’s web site offers a very helpful comparison chart, displaying the specs and prices for the Basic, Legend, Vista, Summit, Venture, and Camo models.
Also, color displays are available in the Legend C and Vista C, and some online vendors offer special pricing on bundles. For example, the eTrex Vista Adventure Pack includes the color Vista C, MapSource CD for any Windows system, data cable, case, and cigarette adapter; all for about $400.
But, let’s get back to basics.
If you’re looking to spend less than $100, the basic eTrex receiver is a rugged navigational unit designed for casual use. This unit can track up to 12 satellites simultaneously, and has an accuracy of within 15 meters. Although the size and shape of the unit fits comfortably in the palm of your hand, you may want to mount it on the dashboard of a vehicle or hang it from your belt.
A number of optional accessories are available, including a swivel marine mount, a bike mount, external power cable with cigarette lighter adapter, and a sturdy holster carrying case.
The Pros
- Small size - The eTrex is the smallest available GPS receiver around. Measuring at just 2" x 4.4" x 1.2", it easily fits in the palm of your hand and the button placement is designed for one-hand use. It weighs only 5.3 oz.
- Display clarity - The eTrex’s display size is 1.25" x 2.25", which is impressive considering the overall unit dimensions. The backlighting is excellent, so you should have no trouble reading this unit in almost any lighting condition.
- Rugged - The rubberized case and waterproof exterior allow this unit to withstand a good deal of abuse, even in wet and cold environments.
- Very inexpensive - The basic yellow model of the eTrex can be found for less than $100, which is the best price on the market for a small GPS receiver.
- Battery life - With normal use, the 2 AA batteries can last more than 20 hours.
The Cons
- Antenna - The eTrex does not allow use of an external antenna, making navigation under tree cover or in high mountains difficult; if not impossible.
- Potential battery loss - Because there is no built-in way of avoiding accidentally powering the unit on (while it’s riding around in a backpack, for example), battery life may be wasted inadvertently.
- Storage capacity - Although one can store up to 500 waypoints, only one route can be stored and this is limited to 50 waypoints.
- Maps - The eTrex does not come with a built-in basemap (nor can it have one uploaded). This makes the basic eTrex unsuitable for city navigation. Also, the display does not allow scrolling, which limits your ability to manipulate the screen image.
- Screen speed - The screen can take some time to update or refresh, particularly in cold temperatures.
- PC interface - The Garmin data cable, used to download information to your computer, is quite expensive. Most users choose to buy aftermarket alternatives. Also, this interface cable is a serial port connector; a converter cable is required for use with USB. And, by the way, downloading data requires this data cable; the unit is not Bluetooth compatible.
Using the Garmin eTrex: Some Basic Facts
The setup process for the eTrex is very straightforward and easy to learn. Users can select from 3 coordinate systems and the preferred choice of navigation units, time format, etc. Complete instructions and helpful tips can be found in the User’s Manual, which comes with the unit and is available for download.All five buttons are on either side of the unit, so you can easily maneuver through the screens with one hand and not block your view of the screen. Data entry is through dropdown menus.
Animated graphics help to identify each waypoint more easily. When tracking the waypoints, the eTrex provides a wealth of helpful data, such as a trip odometer, trip time, location, elevation, maximum speed, average speed, distance to destination, heading to destination and approximate time to destination. The TracBack ® feature allows you to reverse your track log and retrace your steps.
In addition, the unit comes with a wrist strap - a handy accessory for runners, who may want to program their routines as a track and then use the eTrex for assessing progress.
In short, the limited features of the basic eTrex restrict its use to casual navigation. For most purposes, you should plan to use this unit in conjunction with a map. In other words, you would not want to use the eTrex as your only means of navigation and it is not recommended when collecting data where strict accuracy is needed.
The eTrex is also not particularly useful as a city navigator, when a built-in street basemap would be advantageous. However, if you’re out for a run or hiking with map in hand, you will find the Garmin eTrex a handy companion. In addition, the eTrex may be considered a great "starter" unit for those who are just learning the ropes of GPS navigation and want something inexpensive and easy to use as a learning device.
