3 Features to Look For When Buying an Outdoor GPS Unit

When you are looking to buy a new Outdoor GPS unit, there are certain factors to consider in your analysis.

Each product has it’s advantages and drawbacks so the first step is to understand exactly what features you need to have to meet the intended use of the GPS unit.

Someone involved in advanced hiking or boating in remote areas will have different needs from someone who needs a GPS to join in a geocache hunt. This article is intended to help you understand the top three features to consider when looking for the best outdoor GPS units for your purpose.

What built-in maps does the unit have?

When you are looking at the best outdoor GPS units to find the one that fits you, ask yourself this question. “Which outdoor activities will I be doing most with my new GPS?” There are many different possible answers. Road tripping. Hiking. Backpacking. Fishing. Geocaching. Random adventuring. The list goes on and on, and chances are that you do not incorporate all of these activities into your outdoor adventure routine.

This means you have specific needs, so there is a specific type of GPS that you will need. If you are going to use your GPS mostly for finding great fishing spots, then you will most likely be satisfied with a low-budget handheld GPS with no upgrades. These low-priced GPS navigators are still powerful and they are usually very speedy and convenient to use as well. They may not have the most detailed maps but they will suit your needs without putting a giant hole in your wallet. And that’s important.

But say that you are a hiker and as a hiker who likes to go on long adventure hikes you need very detailed topographical maps in your GPS. Well, know that not all GPS navigators come equipped in the box with detailed topographical maps. You may have to purchase them at an extra cost, and this extra cost may be more expensive than the GPS itself.

Loading time and speed.

GPS navigators that come out of the box with detailed topographical maps are sometimes not as speedy as other models with simpler features. So you need to take into account loading time. And this is why if you have simpler needs for your GPS then you won’t need a super functional GPS with tons of built-in maps. You just need a speedy little GPS that is comfy to hold in one hand with simple buttons that will get you to your fishing spots fast. Maybe you do geocaching. Low-budget GPS navigators are usually great for geocaching as well. If you will need detailed topographical maps then you will likely need to have more patience for your GPS to load your positions.

Price and cost of upgrades

It’s possible to grab a very powerful and functional handheld GPS for under 100 bucks. It will load your position quickly even in canyons and in covered places. But there are many upgrades that can make your GPS experience even better. Depending on the model that you choose, you may be forced to purchase upgrades.

For example, if you purchase a model that does not come packaged with detailed topographical maps, then you may find you have to purchase them at expensive costs. So try to figure out what your exact needs are and what you will use your GPS so that you don’t have to spend extra money later on upgrades.

Additional features to look for:

Screen size: Some GPS units have 2.1-inch screens and some have 2.6-inch screens. You may need a bigger screen for your particular usage or you may be able to save money by purchasing a GPS with a smaller screen. The best outdoor GPS units have screens that are readable in good and bad lighting.

Battery life: Many GPS units run on a pair of AA batteries for convenience. However, battery life varies from model to model. Also, some models may require you to run certain features for an extended amount of time which my use even more battery power. The average run time for batteries in a GPS is 14-17 hours.

Do not fail to take into account what activities you will do most with your GPS. Otherwise, you won’t end up happy with your purchase.

The eTrex Venture HC is small and is simple to operate. It is equipped with a 256-color TFT display and you should have no problem reading it during any time of day.

This GPS receiver is very sensitive utilizing WAAS technology so when the unit quickly loads your position from the satellites, you can accurately know your location. Don’t worry about getting lost in canyons and in patches of trees, because this GPS receiver will maintain your position in the heaviest of cover.

You can maintain up to 10 tracklogs plotting a maximum of 500 waypoints. The unit comes equipped with basic maps for lakes, cities, coastlines, rivers, etc.

The unit is designed to be water-resistant and offers computer connectivity via a built-in USB interface. The official battery life is around 14 hours of constant use but this may be reduced if the backlight feature is frequently used.

Pros and cons of the eTrex Venture HC

This unit is lightweight and sturdy. It’s comfortable to hold and the buttons and functions of the unit are simple. For the price, you are getting a very powerful GPS unit that is fast and convenient to use, without some of the hassles of larger GPS models. This model, though powerful, is considered an entry-level GPS unit.

You will find that it is very accurate and fast-loading, but don’t be deceived. This will not feel like a $1,000 GPS model. That being said, if all you need is a low priced, entry-level GPS unit, then we don’t think you’ll go wrong with the eTrex Venture HC. If this will be your first GPS, then you will be happy with its ease of use.

Promised battery life (14 hours) is near the bottom of the range when compared to the existing eTrex models but considering this is constant use, it is still perfectly adequate for most uses. As the unit uses 2 standard AA batteries, it is advisable to carry a spare set of batteries with you for longer trips.

Another reported drawback for some people is built-in maps. Although adequate for some ventures, the maps that come with the unit may not be enough for your hiking needs. Depending on your desired application for this unit, you may need to purchase additional maps from Garmin. If you will be looking for more detail on your maps and you do a lot of hiking, backpacking, and other venturings, then you may want to factor in the cost of purchasing additional maps.

The value for the price is outstanding. If you are into geocaching this should work well. If you don’t mind carrying around a few pair of AAs on your longer trips, then, by all means, look further into this GPS. It’s fast, it’s compact, it gets great reception, and it is accurate. It may not suit each and every one of your needs, but then again we have yet to come across the perfect handheld GPS system. We put it among the best outdoor GPS units out there.

DeLorme is known for making GPS receivers with great built-in maps. The PN-40 comes out of the box with detailed topographical maps for the ultra-adventurous hikers and advanced geocachers. If you need a quality GPS system with detailed maps, it’s hard to pass this one up.

Some previous models had great maps but had slower speeds. The PN-40 from DeLorme has a 32-channel STMicroelectronics Cartesio chipset with dual core processing. What does that mean? Fast. With the PN-40, you get detailed maps without sacrificing speed.

Pros and cons of the DeLorme Earthmate PN-40

The PN-40 is an amazing GPS with incredible capabilities. It is for those with a medium sized budget who have previous experience with handheld GPS units. DeLorme is great at including built-in detailed topographic features in their GPS units. The PN-40 is no different.

Advanced hikers and geocachers will likely be impressed by the mapping capabilities of this device. The PN-40 is equipped with a dual-core processor for faster performance. However, the DeLorme may still lag behind more simplistic GPS units from other makers. If you are into geocaching, you will find that the PN-40 will equip you for truly paperless geocaching adventures.

Although the Earthmate PN-40 from DeLorme is designed for optimal usability, it’s not a touchscreen, and it’s still not as simple to use as other units. If you are considering the PN-40 as your first GPS navigator, you will want to spend some time learning how to use it at home before heading outdoors.

It’s comfortable to hold and intuitive, but will still take some getting used to. The graphics are great. You won’t be disappointed by the aerial imaging in high resolution. The PN-40 is great for basic needs such as tracking your favorite fishing spots. But it’s also fantastic for advanced geocaching and rugged hiking adventures as well.

If you do decide to go on long hiking adventures, you will need to adjust yourself to how the mapping works. You want to get comfortable with it before going out. Battery life? The battery life is average to low-range. You probably won’t be impressed by how long the batteries last. Bring a few pairs of AA batteries with you on your GPS adventures.


Summary of the DeLorme PN-40: Is the DeLorme Earthmate PN-40 a great value? We believe so. If you know how to use a GPS and don’t have extremely specialized needs, the PN-40 should amaze you. The maps are great. It’s speedy, and it’s handy.

Note that the 60Cx does pull power from the batteries even when it is off, and you may want to consider purchasing rechargeable batteries for this unit.

So while the 60Cx does have its limitations, it has many strong points as well. You will be pleased with its durability, its ease of use, and its speed.

For the money, you are getting a very advanced, very powerful GPS device. Not all purchasers of this device are pleased, but if you need a handheld GPS unit that is fast, lightweight, simple to use, and powerful, then you should strongly consider purchasing the Garmin 60Cx.


The Garmin GPSMAP 60Cx is a great handheld navigator and is simple to use. However, you may need to purchase additional maps from Garmin. If you are looking for the best outdoor GPS units, you have to consider the 60Cx.

If you are just trying to keep track of your location while on fishing trips, this unit should work surprisingly well because of its price and ease of use. Its simplicity puts it among the best outdoor GPS units. You probably wouldn’t need any extra maps.

The eTrex H is a great first GPS navigator because it offers powerful features for those on a low budget. We also put the eTrex H among the best outdoor GPS units.


How does an outdoor GPS unit work?

GPS stands for Global Positioning System. An outdoor handheld GPS unit receives signals transmitted from satellites to help locate and track your current position on various terrain.

It used to be that the first handheld GPS units did not function well at all in covered places such as forests, canyons, etc. Now many of the newer handheld GPS navigators are more advanced and can usually receive signals from satellites even if you are positioned in a forest or another covered place. This does not take away from the fact that your GPS unit needs to contact a satellite way up in the sky and so you will receive the best signal if the space between your receiver and the satellites is unobstructed. As time goes by and technology continues to advance, GPS receivers will become more reliable and will work in more covered areas.

How exactly does a handheld GPS work?

All GPS satellites transmit their signals at exactly the same time because they are all synced with clocks at the U.S. Naval Observatory in Washington, D.C. These signals are extremely fast and if the space between your GPS receiver and the satellite is not blocked, you should be able to track your position with great speed. This also depends on how much detail you are requiring on your map.

Your handheld GPS receiver will usually coordinate with multiple satellites in order to determine your current location. Even though GPS was first intended to provide locational data for ships, it is also extremely useful in the air and on land. This is why many fishermen will use GPS units to record coordinates for their favorite fishing spots, and hikers will use them to evaluate different types of terrain and estimate the time it will take to navigate around hills and cliffs.

When you turn on your GPS receiver it will coordinate with multiple satellites, sometimes several, and will then begin to receive transmissions from the satellites to gather your position. Remember that your receiver unit does not transmit signals to the satellites. Your GPS navigator is passive and only receives signals.

How accurately do the satellites determine my location?

The best outdoor GPS units are quite accurate. However, some GPS receivers are more accurate than others. It is common for handheld GPS receivers to determine your location within 30 feet. Other more expensive receivers may be more accurate. Handheld GPS units are usually not as accurate as larger GPS units and those units mounted in vehicles.

How hunters, fisherman, and explorers use GPS receivers

Say you’re fishing, and you find your special fishing spot where the sport is especially good, and you need to remember exactly where you are so that you can get there again. So when you are in that special location, use your GPS receiver to get a reading of your position and then record that position into your unit’s memory. The coordinates or locations that you record are called “waypoints,” and the next time that you return to the location just tell your receiver to locate that waypoint again. The receiver will point you in the direction of the location you want to navigate to, and it will then likely be able to show you if you are of course and your estimated time of arrival. There are many uses for GPS receivers, whether you are geocaching or whether you just like adventures and exploring.
