Things to consider before buying a portable GPS device

Portable gps devices are quite convenient.  You can take them anywhere.  This is the number one reason why many people wants one, especially those who are into such sporting activities such as hiking, hunting or camping.  

Since they are affordable many more people are able to buy them now.  Yet, before you go off and buy one you should consider a few things.

First, you should understand how a GPS device works.  GPS stands for global positioning system.  It works through a computer system and satellites which orbits the Earth.  Together, these computers and satellites can pinpoint a precise destination, person or find directions to a certain spot.   They can do these by tracking simple radio, computer or other modem technologies. 

GPS systems was first introduced by the Defense Department for military purposes.  But now they have advanced to the consumer market as well.

A portable gps system is one that can be carried around easily or moved from point to point easily.  They can come in a number of sizes.  They also have a variety of capabilities. Of course, the more functions a unit has, the chances are the more expensive it is to purchase.

Before you go shopping for your next or first portable GPS device, it is a good idea to actually think about the capabilities or functions that are actually necessary for you and your needs.   By doing this, you may be able to fight the urge to buy a more expensive model, with extra functions, that aren’t really necessary for your use.

One thing you should realize is the fact that you may have to purchase a higher price device to get a good signal.  All GPS systems must have a clear access to the sky in able to work properly.  If buildings, trees or vegetation blocks that access, the system can not function or signals will drop off and on.   If you plan on spending a lot of time in these types of areas (for instance hiking in a forest), then you may need to purchase a GPS device that has a higher frequency level and this means that it will more than likely have a higher price tag as well.

What else should you consider?

What about the time in which it takes the GPS device to start?  Some systems, even the portable ones, will start quicker than others.  Some have what is considered a long or cold start up time.  This means it could take a few minutes before it is up and running.  Are you the patient type?  Will this annoy to no extreme?   Inquire about the start up time when purchasing a model.

What about the time it takes to charge the battery or batteries?  Most portable GPS devices will run off of the common AAA battery or a built in rechargeable battery.   You should inquire about how long it takes for the battery to charge and the estimate time of life for the battery or battery charge.  Generally, the first charge will take the longest amount of time.

Mapping capabilities is definitely a consideration that must not be overlooked.  This is how you will find your way from place to place.  You need to not only be able to understand it.  You need to like the size of the screen, the format, the color and even the style.   Colored screens usually cost more than the black and white ones do.  But most people prefer these because they say they are easier to understand and read.

You should also inquire about how the unit is able to update its mapping functions.  The two basic ways that portable GPS devices do this is by connecting to a computer or a flash memory card.  (Generally speaking those units that can connect to the computer to update their map functions are usually cheaper than those that uses flash memory cards).

You should also consider the type of device you want.  You can choose from such devices as:

Pocket sized portable GPS which usually runs from recharegable batteries.  These can also be used in automobiles.

PDA’s devices which are equipped with GPS capabilities.  These usually run on rechargeable batteries.

Cell phones that are equipped with GPS capabilities.   These are also run from rechargeable batteries.

If you are considering buying a new or your first portable GPS system, you will be glad to know that you won’t need to hire anyone to install anything.  You just turn the system on and it is ready to go.  You also don’t have to pay any activation fees or monthly payments.  If you choose to purchase a subscription such as traffic information, satellite or weather information, then you will have a subscription price.

Your final consideration is this.  Would a portable GPS system make you feel more secure the next time you are out on the hiking trail or looking for that cool vacation site?
