A guide to buying GPS

Ranked #12,429 in Computers & Electronics, #250,754 overall

People have been navigating for thousands of years with a compass, this can be quite accurate but requires alot of skill to get it right and you will also need a good quality map to plot your position accurately and will also be dependant on the weather conditions as if you are in limited visability it will be much harder.

Now a days the easyest way to find your position accurately and plot a route very accurately and quickly is with a GPS device. This system will use 3 or more satalites to plot your position these devices are very accurate and can plot your position from 15 meters or 50 foot to 30cm or 12 inches dependant on the device you have.

They now incorparate maps downloaded into most devices which will allow you to plot your routes, which makes navigating in your car very easy and will stop family arguments about which way to go on your trips. The GPS systems have revolutionized travel and most forms of transport now use GPS. Everything from Planes, boats, ships, cars, cyclists and walkers are all benifiting from GPS systems to plot position and routes. Why not invest in a GPS system for your family and you will never get lost again, Hopefully!!!!

Questions you might need to ask before buying your GPS

Questions that you may want to ask.

Does it have the specs you need? Don't go overboard in weighing this. Most gps receivers have very similar specifications.

Can you easily find the data you need?
Do you have to change pages more often than you like?

Does the data have all of the formats you are interested in (grid systems, datums). If you want it to work with paper maps then learn about this before buying a unit.

How's the configurability, customization?

If you want a computer interface then does it support one?Can you get the programs you want to work the gps?

How is the screen display? Is the text easy to read?

Do you need an external antenna? Most of the time you don't but you need to evaluate this for yourself.

Do you want or need internal maps? Do you need to update them or provide more detail?

Is waterproof important?

User interface ok?

How's the battery life?

Available accessories, mounts, cases?

If you need built-in maps then how accurate are they? No current maps databases are as accurate as you probably thought they were.

Can the unit be upgraded? In this high tech market firmware upgrades are important.

Do I need dpgs? - an optional hardware unit that provides increased accuracy.

Do I need WAAS? WAAS can provide corrections similar to a beacon receiver and uses the same antenna as your gps receiver.

To get answers to these questions you can ask the salesman, but you may not be able to trust the answer unless you get one that understands gps receivers. A better route is to go to the manufacturer's web site and look up the data. They often have manuals available on-line so you can download and read about the unit you are considering. If you have friends with gps receivers that talk to them but learn a little first so you can speak the same language. Many gps users claim that the unit they decided on is the best. This may be true, but filter out the reasons and make sure that it is the best for what you need.

There are also some questions that you don't really need to ask:

Does it work outside the US? All receivers work anywhere in the world except units that only work with a laptop using a map display. Some of these won't work outside the US only because they need a map and may not provide any non US maps. This is another good reason to select a standalone unit.
