Pros:

Upgraded display

3.7 GB of storage

Built-in sensors

Cons:

Preloaded maps aren't great

This is an updated version of Garmin's eTrex, and it boasts a brand new color display and is waterproof. Let's find out some more details on what makes the Garmin eTrex part of our top ten.

Read more

Software
According to those who have used this device and love it, one main gripe was that the pre-loaded maps were not that great, so opted to add their own.

The Battery
This GPS on a fully charged battery will last 25 hours, which is more than enough to get you through a weekend in the wilderness. Great battery and one that you can rely on when you are away from civilization and only have your GPS equipped.

Display
This GPS comes with a 2.2" color display, which may seem small, but is highly accurate. Testers liked that it was a good balance between power efficiency and fantastic visibility. To take full advantage of the smaller screen, TOPO 24k maps are great high definition topographic maps that many hikers tend to use.

Wireless/Bluetooth Functionality
And of course, in our modern age, this device is wirelessly compatible with other's devices to share tracks and routes. If you come across a special spot and meet other hikers on the way, you can simply direct them to the spot by sharing it through your eTrex 30.

Criteria Used for Evaluation

Use

While some of these GPS’s have other functionalities, and some simply just have an internal GPS implemented, the main point of your GPS search should be finding the most accurate and fasted model possible. All the fancy design features and extra functions aside, this is what makes GPS’s so popular. When trying to decide, which ones have the best GPS, you can keep a few factors in mind.

First up, keep an eye out for models that sport a high-sensitivity GPS receiver. This is more than a fancy labeling gimmick and accomplishes more than just sounding cool. A GPS with a high-sensitivity receiver will use large banks of correlators and digital signal processing to produce signals as quickly and efficiently as possible. This makes the signal outdoors extremely fast, but also makes indoor signals useable. Due to the extra processing power, these types of GPS’s can integrate weak signals into a position.

During this list, you also may have noticed some models sporting a certain number of channels. This can be very confusing and is so in-depth that you could write a paper on it. To save you the time and sanity, here is a quick explanation. When a GPS has 66 channels, then it can track the location of that many satellites at the same time. Now, there are not nearly that many satellites in orbit so what is the point of going to a number that high? To speed up the process, as satellites must first be acquired when they come in view of the GPS, multiple channels can look for the same satellite.

The last two points are great to keep in mind for traditional GPS’s, but there are special versions out there. One on this list, in specific, is a GPS that will track your vehicle or children. Models such as these will be used in an entirely different way, such as for tracking your vehicle in heavy populated areas or making sure your teenager is not out partying.

Battery Life

With technology devices like GPS receivers, a key factor that always comes into play is the battery life. That and what type of battery design is implemented. For example, is there an included battery that comes with it, is it removable? Or, do you have to put AA or AAA batteries inside? For pure performance, you will not need to concern yourself with which type of battery is utilized. But, some people may prefer one method over the other.

Let’s start with GPS’s that require AA or AAA batteries. The most obvious problem with this method, for some people, is that you are required to add and remove new batteries when needed. Plus, if they die and you do not have replacements, you can’t operate it unless you buy some new batteries. However, there are a lot of options at your disposal with this method. For example, it is your preference to either buy cheap batteries (such as Alkaline) or premium batteries (such as Ultimate Lithium). This will have direct implications on how long the GPS will last.

What about models that have a built-in battery? Mainly, the best aspect is the ability to charge it anytime you, please. If it runs out, if you have the means to charge it, you can still use it. Most will do so via USB, so if you are on the road you probably could charge it in your vehicle. If the battery is not removable or not a universal design, though, the biggest issue can be if it reaches its shelf life. At this point, you may have to buy a new GPS (if there is no way to get a new battery). As far as how long they will last, in general, most will last several hours before needing new batteries or a charge.

Visibility

This will weigh differently from one person to the next, as the display will not affect the performance in any way. But, for some, it could be a deal breaker. Much like a smartphone or laptop, for some, the resolution and clarity is the most important aspect. After all, it is beneficial for you to see the GPS information that is in the palm of your hands. While it is very rare for GPS’s do not have a display at all unless they are designed for special purposes or to be connected with an additional source, some sport better ones than others.

As they are small in nature, the amount of space the display takes up is a factor to consider. Thankfully, it is not difficult to find this out as all you need to do is look at a picture of the interface. Some will have a half screen and half buttons, while others will have a full display with touchscreen controls. Speaking of a touchscreen, that is another factor. If you prefer keys, then avoid GPS’s with a full-screen display.

Proper backlighting plays another role and allows you to use the device at night. But, in the daylight, a backlit screen may reduce battery life so you could also look into ones with dimming control. Lastly, some versions will have a monochrome display. Meaning, either a black and white display or one that focuses on one central color.

Connectivity

This is where GPS devices transform themselves into more than what they were designed for. Most will just expect a GPS to be a logical way for them to receive directions and understand where they are at all times. But, they can do so much more than that with their wireless and Bluetooth functionality. Not all of them will possess both, or even one, but the models that do hold enhanced value. Especially, for those that utilize Bluetooth technology.

For a brief explanation of what Bluetooth technology is, it allows you to sync data from devices that have it enabled. So, both devices need to have the technology in order for information to be synced. With GPS’s that have it, you could connect them to your laptop, smartphone, and tablet. Some models will have more use for it to upload your data on different types of applications, while others will utilize it for you to navigate through more free maps.

With wireless capabilities, some GPS’s will track and map with Google maps over the internet (doing so in real-time). Then, there is Garmin Connect. With all the entries on this list, Garmin proves that they are a frontrunner in GPS technology. One of the reasons why is their products utilize Garmin Connect, including their handheld GPS’s. With this software, you can get a detailed analysis of your activities, send tracks to your outdoor device, upload data and view it on other devices, and share routes and geocaches between units.

Of course, as with the display, you can make the claim that these types of features are not prevalent in the overall performance of a GPS (at least for the versions that do not require Bluetooth). But, this type of technology can make a good product a great one.

You Do Not Need to be an Expert

GPS technology can be extremely overwhelming and for those of you who do not know much on the subject, do not worry about it. To use and enjoy a GPS handheld, you do not need to be an aficionado of GPS technology or need to understand every single process. The point is they are convenient devices that will assist you in getting you where you need to go. As you have seen, some work a little differently than others, but the overall point remains the same.

Portability is key

When looking for a handheld GPS, you want to make sure it is actually handheld and will be easy to transport but at the same time give you the accurate information you need while out in the wilderness. Many of these GPS units will be great for portability, but always check to see that they will fit in your pocket or conveniently in your backpack.

Display

Make sure when looking for a GPS that the display is easy to read and will give you accurate information. What good is a GPS if it comes with all the bells and whistles but you are not able to read it accurately. The best way to ensure you are getting a device that will give you an accurate reading and visual display is to check the customer reviews. Another thing to consider when dealing with the display is that the display will have a backlight, so if you are trying to read your coordinates or location during the night, you will be able to accurately see.

Other Factors to Consider

Advanced Features

At this point, it has been drilled into your cranium but these devices are very diverse in nature. At least, some of the most elite models are. There are a plethora of extra features that you can look for and they will vary from model to model. While you should not expect to hold a full-length phone conversation or stream a Skype call, there are useful functions that GPS devices can perform past their original intent.

Firstly, you have the additional information that some can display that may not be much use to you. For example, ones that come equipped with the ability to monitor your heart rate. Or, the models that display basic hunting and fishing information. If you do not care about hunting, fishing, or fitness you may have zero uses for that type of information. Models that work as radio transmitters may also include the means to get in touch with a search and rescue monitor center in the case of an emergency, which could be handy if you have a fear that something bad is going to happen to you.

The way you want to use GPS could also be different, so you could find restaurants and stores that are located near your area. Then, there are models with microSD card slots. These become useful in situations where you require more detailed street maps. Simply, insert a card with this type of data and some will then display for you turn-by-turn directions to your intended destination.

It is a mouthful and a handful to consider, but just disregard the features that have no meaning to you. From person to person, this will vary so tread carefully in this compartment.

Ease of Use

If you were keeping the score at home, you probably noticed that a lot of the entries on this list had similar issues. No product is perfect, so flaws will always be present, but there are some that could sway your decision. Three really important ones to keep in mind is how detailed the instruction manual is, if the included maps are too basic (if it has maps) and if it requires a subscription.

As far as the manual goes, the more you use the device the less you will need it. But, at first, GPS’s can be very confusing and it helps when the manual is detailed enough to inform you of what to do. Some have manuals that do the complete opposite and provide you with useless information. Then, there is the issue with the maps (with ones that have them). With Bluetooth, some models will allow you to gather more detailed versions. But, not all have this benefit and you may need to buy detailed maps. Lastly, some systems will need an active subscription to function properly. You may not be interested in paying anything past the initial price tag.

GPS is a technology that most people are aware of, but one that few probably fully understand. A common question when it comes to this, is who controls GPS? To better explain this, it is important to know that GPS stands for Global Positioning System. This is a space-based radio navigation system that is controlled and monitored by the United States government. GPS coordinates are not randomly given to you by software or program.

Although the United States is the primary system used around the world, other countries are developing new systems to eventually join them. However, when it comes to operations and management, the U.S. Department of Defense is responsible. Because the U.S. Coast Guard serves as the civilian interface to the Department of Defense, it is then their duty to communicate GPS information to the public and report any issues that happen. Clearly, this is coveted technology and the United States does not want to mess around with who operates and maintains it.

q: Can You Use Your GPS Internationally?

a:

Alright, so enough with the history lesson. Let’s now dive into some questions that you can take with you in the real world. Some people either want to travel to another country or live in one altogether. This then begs the question, do GPS’s work in countries outside of the United States? The simple answer is yes, as GPS receivers are designed to work anywhere in the world (as far as location goes). However, there are some precautions that you should be aware of. Most notably, for GPS devices that can store maps, is that map data could be hard to obtain.

With certain devices, they will only be of use to you if you can download map data in your area. Chances are, in a different country, this map data may not be available to you. So, if you are trapped in Japan and have no idea where you are, random latitude and longitudes may not assist you that much. However, when you are visiting another country, it is wise to at least have some sort of GPS to help you navigate (even if it only minorly helps).

q: What is Geocaching?

a:

It was not mentioned too many times throughout this list, but you may have overheard the term geocaching before. If you have, do you know what it is? It may come as a surprise, but geocaching is nothing more than a recreational outdoor activity that utilizes GPS technology. Basically, it is a real-world outdoor treasuring hunting game that requires you to navigate to a specific set of GPS coordinates. The end result is to find a geocache container, which can be considered the treasure.

All you need to join in on the fun is a GPS device, such as the ten that were listed, and a basic membership at Geocaching.com. Once you have confirmed your free Basic Membership, with the option for a Premium one if you like, simply enter your current postal code and click search on the “Hide & Seek a Cache” page (all done on Geocaching.com). Then, choose a geocache from the list and load the coordinates into your GPS device. From there, treasure on to find the hidden geocache, but make sure to return it to its original location for future treasure hunters.

q: Will GPS Devices Work Underwater?

a:

Much like with other technology devices, some GPS handhelds are protected with some sort of waterproof or water-resistant technology. There are limitations and some will just protect against light rain and accidental splashes, but not if it is submerged in water for a certain amount of time. However, the reality of the situation is even if a GPS device is designed to withstand gallons of water it would not work properly. Nope, not even if you were in a container (such as a submarine) underwater it still would not function.

Why may you ask? It is because of the way that the GPS receives directions and specific coordinates. What happens is they listen to signals from various satellites in space. From there, they will mathematically calculate their own position in reference to the satellites. But, this technology does not work as well, or at all, underwater. As Joshua Niedzwiecki, the BAE Systems director of sensor processing, points out radio signals do not broadcast very far underwater. Though they are constantly developing the technology to overcome this, for now, it is just like if you tried to use your smart phone deep into the ocean. Eventually, you would lose all connectivity.

q: Do You Need the Internet to Use a GPS Device?

a:

Some specific devices will utilize the internet in some way, or Bluetooth. But now that you know the process of how a GPS works, this question should be easy for you to answer. Because GPS devices receive signals from various satellites that are floating in space, the internet is not required for them to function properly. Even for specific versions that allow you to upload for detailed maps into the system, the internet is not required for this. To download the maps on the SD card, to begin with, unless pre-installed, you may need the internet. However, there is no need for concern if you have no access to the internet; the GPS will still function as designed.

q: How Well Will GPS Work Indoors?

a:

As you are starting to conclude, GPS technology is a little limited in terms of usability. You now know that it will not work underwater and can be extremely limited in other countries, but it also does not function superbly indoors. Technically, it can be used but it may not be very useful to you. When trying to use the satellites to receive a signal, the walls, roofs, and other indoor objects reduce the effect of the signal. But, there is a system out there that was designed for this very purpose.

An IPS, which is an Indoor Positioning System, is a system that is specifically designed to locate people and objects that are inside of a building. They achieve this using radio waves, acoustic signals, and various other sensory information. However, integration between the two separate technologies can be made. In specific, GNSS receivers that have high sensitivity are able to adequately receive satellite signals in most indoor environments.

q: Do I need my GPS to be waterproof?

a:

When looking to get a handheld GPS, you want to make sure that it will be rugged and hold up to the terrain you are set to take it. The first thing to consider is where you will be going, and decide on investing in a GPS that will hold up to that terrain and weather conditions. Having the ability to have a waterproof GPS is always a great feature, just in case you get caught in some nasty weather. Most of the GPS's on our list are water resistant, but the best way to ensure is to do the research and also check the customer reviews.
