Pros:
  • Adaptable to many different situations
  • Quite accurate in open environments
  • HotFix technology improve reception in covered or rocky locations
  • Compact and convenient to carry
Cons:

Although the Foretrex 401 isn't as fancy as Garmin's GPSMAP 64, it is much more compact and convenient to take along. With its wristband, you'll have the luxury of keeping your hands free.

Read more

This model operates with a high-sensitivity receiver, just like many other Garmin products. The Foretrex also features HotFix, which improves reception performance when moving through heavy woodland canopy, or even when traveling between rocks in a canyon type environment.

The display size is small, but the layout is pretty well organized. the user can view the dual position readout in several different formats. Some of the modes featured on this unit include sunrise/sunset times, electronic compass, barometric altimeter, trip computer and even fishing and hunting information if desired.

In addition to the normal stuff that a GPS unit does like tracking current location, travel routes, and waypoints, the Foretrex also supports a heart rate monitor, which can be purchased separately. Another useful tracking aid is Garmin's TracBack feature that allows the user to retrace the traveled path steps to find their way back.

This unit runs on two AAA batteries, which do not last as long as some might like.

As for durability, this product has been used in combat situations, standing up to most of the rigors. So, it's safe to say that it will make it successfully through your run.

As mentioned before, this model doesn't have all of the frills that you may find in another model but it performs exceptionally for what it was designed to do.

Pros:

User friendly design

Detailed user guide

Cons:

Some skipping and lagging reported

DeLorme, actually a Garmin brand, produces some pretty reliable products. One of those being their inReach SE handheld "Satelite Communicator". This isn't simply a map or a directional way finder like the other devices on this list, but a useful tool with critical, or even life-saving features that will absolutely come in handy if you find yourself lost or experiencing a problem in the middle of nowhere.

Read more

Although the inReach SE does track your location, its key features go a whole lot further than a simple GPS. This device can be paired with a smartphone to download topographical map content, but its communication capabilities are what really caught our attention.

This unit features an SOS option, which alerts a monitoring center of your call for help and accurate grid location, with a push of a button. That certainly adds some extra confidence to an off-road run or hike.

Additionally, the inReach SE tracks your trip with data such as GPS coordinates, elevation, course heading and even speed of travel.

And a really cool plus, you can also send and receive text messages with this unit. This would be handy in a situation where you may somehow get separated from your travel buddy, or need to communicate important information in the event that you get seriously lost, and must be located.

The rechargeable internal battery will allow roughly 100 hours of continuous use when fully charged. That figure is based on tracking intervals of around ten minutes each in an open environment, with clear access to the sky.

Pros:

  • Able to load third party and custom maps
  • Holds a ton of geocaches
  • 3 inch sunlight readable screen
Cons:
  • Short battery life
  • Customer complaints of the device freezing

Here's one from Garmin. The Oregon 600 has a slightly larger screen when compared with other handheld models of this type. This is a great piece of gear to help you navigate your way through deep trails, or even a hike through the hills.

Read more

Getting right into it, the Oregon 600 operates with a 3 inch (7.62cm) display that doesn't get washed out under bright sunlight. Its multi-touch capability allows faster data entry and searching.

The navigation runs with Dual-band GPS/GLONASS satellite positioning and is also equipped with Garmin's HotFix. This is a satellite prediction technology that allows quicker and more precise location of the unit's position.

Connect the unit to your PC and set up your upcoming trip or route with 2D and 3D maps. Plus, the Oregon will hold just about all of the geocaches that you can download.

Like almost all Garmin GPS devices, you can add more maps to the unit's database. In addition, you will be able to share your tracks, routes and waypoints with other wirelessly compatible Garmin devices. You can even send larger files like custom maps and images. You can do it all, just by pressing send.

The Oregon is powered by 2 AA batteries or a rechargeable NiMH battery pack. There is a bit of feedback stating that the battery life doesn't last as long as many would like.

Criteria Used for Evaluation

Features

The first thing to look at was how well the actual devices positioning works, how accurate it is in terms accurately identifying the exact location of the user.

Can a route be planned on a computer and the route loaded into the model, what Bluetooth capabilities it has, is the screen appropriately touch sensitive?

What are the Geocaches, Waypoints and tracks capabilities for the model? Anti-glare or clouding factors for viewing the screen, how much direct sunlight or nighttime effects the quality of the view screen?

Power Source

Does the unit stay connected or are interruptions happening which are known in some particular models, for example, if a hiker, runner or traveler enters a ground depression such as a valley or canyon will the Satellite be able to connect with the GPS UNIT?

What was the average memory capacity provided with various models?

Though the devices are handheld can they be carried on running clothing or attached to backpacks?

Pre-loaded with plenty of maps, some units are and some are not, we also wanted to know if an SD card can be used to increase memory and store more maps and data?

Durability

How durable is the device, is it shock resistant, is it likely to break or stop functioning if it takes a hard knock?

Is it easy to carry? after all its a handheld device but can we carry it “hands-free” on some models yes we can as they have been designed to attach to cords or loops. Some models are small enough to slip safely into a small pocket.

Waterproof factors were important because out in the wilds during hiking it could be dropped into a stream or deep puddle and the device will need to survive this and continue to function.

Responsiveness

The quality of graphics displays on the screen, how clearly is the surrounding terrain shown, is it realistic or looks like a cartoon? Which devices employed Satellite Bird’s Eye view tech for a very real-time view?

Is the device “ user-friendly” can it be operated easily or is it difficult and time-consuming?

Were any devices capable of being updated to keep up with technological advances?

Have A Back-Up Plan

Although all of the GPS devices listed here are reliable and shouldn't run into any problems, it's still highly recommended that you invest in some kind of backup strategy if you plan on taking these out on any long hikes or backpacking trips. Either a backup GPS device or a physical map would be effective in this capacity.

Know The Difference

Some wireless products, including these GPS devices, are either water-resistant or waterproof. The difference between these two terms is important: water-resistant means it can withstand brief exposure to water without malfunctioning, and waterproof means that it can withstand full immersion for an extended period of time.

Other Factors to Consider

Advanced Features

Navigation has come a long way in the last 100 years and now thanks to the features in modern GPS devices, we can do in seconds what would have taken half an hour or more to do years ago.

Nowadays to find our way around we can get a GPS and feel confident that we won’t get lost, but it’s not always been that easy. Imagine if you were at sea a hundred years ago. You would need the following just to start your trip with a reasonably accurate idea of where you are going.

A Marine Chronometer so that you could figure out time.
A Sextant so that you can figure out which angle to travel.
You would need an Almanac to figure out the schedules for the coordinates of stars.
A full set showing sight reduction tables so that you can figure out azimuth and height computations.
Finally, you would need a map of the region you intend to travel in.
A trusted compass.
A pencil/pen and paper/notebook.
To travel around on land or sea without getting lost we needed to understand latitude and longitude.

Use

The modern GPS is so much easier to use. Before GPS devices were available widespread, we had to figure latitude and longitude calculations by hand. To work with this so you knew where you are and where to go you first needed to measure the Sun altitude ideally at mid-day (noon). If not this way then simply measure the altitude of any convenient celestial body while crossing the meridian at its maximum altitude when due south or north, while constantly measuring to keep track of the north star, providing the star is visible, which it isn’t in the southern hemisphere.

Once you have taken these measurements you take out your tables of almanac corrections which will let you figure out your current latitude to around a fraction of a mile. Remember to make sure your longitude angles are measured from the horizon, though it’s possible to take a measurement from the zenith directly above you that can only be done if the weather is not hazy. When you are using the horizon to take measurements, if it’s a hazy day, simply use an artificial horizon by using a pan of reflective fluid, preferably mercury.

Ok, having done this and feeling ready to go for a nice long run ( or a trip) quickly figure out your longitude.

It’s done in much the same way providing you get your measurement angle via Polaris, which creates a similar measurement to the star nearest to the west and east horizons, if you do this you have your needed longitude. Be aware of a possible problem, the planet rotates at 15 degrees per hour, so if you base your measurement on the same calculations you made yesterday, you will be wrong and you will get lost. So you must factor in the time difference in relation to the rotation of the planet. Right, you are now ready to set off and I hope you marked all your information onto your map and you have also brought your compass.

Things are so much easier now thanks to the usability and conveniences of the GPS!

Value

We looked at the cost in relation to what the GPS device offers? Generally, pricing for units came over as realistic in fair when comparing cost against the features provided. The rule was consistent, the more you pay the more you get.

The conclusions we came to are that some systems are designed with basics in mind and that this meets a good market niche, middle range units have a substantial market niche and high-end devices are very specialist and serve for conditions or environments which are much more demanding.

No one likes paying a lot of money for things but when it comes to something as important as your GPS investing more upfront in a quality unit is an investment that will more than pay for itself in the long run.

Frequently Asked Questions

q: Does a GPS ever disconnect when you don’t want it to happen?
a:

Yes but it depends on the amount of tech built into the GPS. If you buy cheap you might experience disconnections if you’re in very sheltered terrain such as a canyon.

q: Can we purchase a smartphone with built-in GPS capabilities?
a:

Yes, there are phones with high tech GPS and radio phone capabilities which puts them close to being called “smartphones” However it is not advised to rely on phones for GPS as they are limited tot heir fucntion and memory and often have issues with connection and service in remote areas where the phone's service is limited. Also, keep in mind your GPS connection is going to get you billing charges from your phone services provider because of how you are connected and using your data.

q: Do handheld GPS systems have other uses?
a:

Some do, you can record yourself on video, record your voice, plan hiking routes. In fact, GPS technology is growing to include many additional functions. Many allow you to upload reports and information about your walks and runs to your computer so you can view your porgress and print off reports.
