Choosing a GPS
The first thing to decide is how you plan to use a GPS and the second is the amount you plan to spend on a GPS. Are you going to use in the car, for hiking and trekking, or for hunting or fishing? Today's GPS receivers are limited in what they can do and are optimized a specific purpose. There are GPS specifically for flying, others for hunting and / or fishing, and car navigation. Some are just an electronic map showing its position in the map screen. Others have no maps at all and can be very well if you just want to know your longitude / latitude.
If you plan to use your GPS in a car, there are several options: a basic or mapping handheld receiver, a dedicated automotive receiver, a GPS with a PDA or handheld GPS.
Though the computer hand can be used in a car there are several drawbacks, the screen can be hard to see because of their small size and some units will have to be willing front on the dashboard where you can get a better signal. With a nonbasic (mapping) unit that can tell where is the time they have a paper map with you to interpret the data.
An allocation unit is the most useful to follow generally involves driving the roads. A receiver dedicated motor is larger than a handheld in order to accommodate a screen large enough to be seen while driving. They are powered by the car's electrical system and because of this, but can only be used in a vehicle. Car units usually have voice instructions that allows navigate without taking your eyes off the road. Prices start at $ 500 U.S..
A GPS with a PDA needs clear access to the sky for satellite reception. Some receivers have built-in antenna or have the ability for an external antenna. An antenna on the seat of your car can and can not work. The console is the next best place – Reception may be questionable. An air duct assembly is better and a windshield or the antenna placed all the way forward on the dashboard is better yet. The most reliable place is for an external antenna to be attached to the roof of his car.
A laptop GPS requires a CF to an external antenna, a receiver Bluetooth GPS, a mouse type GPS receiver, or be connected via a cable to a handheld GPS unit so that the receiver can be placed in a position for a good reception. Of course, a laptop is great, but the main advantage is a very large screen for maps. If you have a need for a laptop in the car, this may be the best option and a mouse receptor is economic.
If you plan to use your GPS for hiking or backpacking there are three options, receiver-based handheld, a GPS receiver and mapping with a handheld PDA. It is also recommended that in addition to your GPS, take a sheet of paper and the compass magnetic, and extra batteries. Weight and size should be considered when deciding which GPS to choose. A basic receiver are not capable of mapping, however, show its location in a format you choose, and most likely latitude / longitude. Provide paper maps have chosen the format of the position marked on them, your GPS will will find its location on the map. If maps are not formatted the position of systems, and marked, this is something you want to do yourself. These range to be the least costly options for GPS, often less than U.S. $ 100 and are as accurate as more expensive units, only that it has so many features. The characteristic main they lack is mapping capacity.
For hunting or fishing many handheld models include best times for hunting and fishing for a particular location and date. Mapping handheld receivers are bigger, heavier, and / or have a shorter life battery that the basic units. Shortest battery life means carrying more extra batteries adding bulk and weight. With a portable drive mapping will have the benefit of having the maps displayed on his GPS. It also includes other benefits such as a barometric altimeter, electronic compass, games and a schedule and can plan your route before time on your PC and upload to your GPS. These units display with preloaded maps and map detail is reflected in the size and screen resolution. This means that mapping units are generally larger than basic units. The downside of a GPS with a PDA is that it will drain the battery faster and also the top of your PDA. The mapping units are more expensive than the base units, prices start at U.S. $ 150 unless you get one with Bluetooth capabilities, which are more expensive. For fishing a plotter / GPS or a GPS spacecraft are also available. The GPS chart plotter and GPS sensors typically have a lot of features and start at $ 400 U.S..
