Navigator selection: device characteristics

Modern navigation systems are used in aviation, road transport, and marine technology. Without them, many do not think themselves to travel. Navigators are necessary for pedestrians, athletes, motorcyclists and cyclists. The most demanded are devices for locating and navigating the way that motorists use.

It is quite easy to choose a navigator, if it is known in what conditions it will be used. Looking for the device, you should pay attention to the software and cartography. Usually a set of cards are sold together with a navigator. Before buying it is necessary to check whether all the necessary localities are present on the map. In Russian conditions it is best to use the programs of domestic developers. The most popular are Navitel, Avtosputnik, Garmin and others. Some devices are able to work simultaneously with several navigation programs, but there are also models that use only their own software. Carrying out the choice of the navigator, it is necessary to take into account that models without maps are able to show only the coordinates.

The price and usability depends on the screen size.

Usually it is from 3 to 7 inches (but there are models and larger format), can be colored or black and white. The small screen is most convenient for using with portable devices, the big diagonal is advantageous in that it allows viewing video files.

The price and choice of the navigator for a car depends on the material from which the device is made. The body of the product is usually made of aluminum or plastic. For athletes and tourists, shock resistance and water resistance are particularly important.

An important parameter is also the amount of memory used. As you know, it does not happen much. For large volumes, you can view the map in more detail. Almost all modern devices except their own resources allow you to connect external cards larger than 2 GB.

The choice of the navigator is also impossible without taking into account the power of the built-in processor, which determines the speed of scrolling the map and its scaling. Here, too, the rule "the more, the better". For athletes and tourists, the dimensions and weight of the device are important: the device should fit comfortably in the hand and have a low weight. The power of the navigator is also different. The device can take energy from the car's cigarette lighter, from finger batteries, as well as from an ordinary power supply. Most devices have mixed power.

Some navigators can be equipped with additional functions that expand the capabilities of the device. Speleologists and climbers can not do without an altimeter and a barometer. Voice messages, DVR, indication of traffic jams - these functions, of course, can affect the choice of car navigator. There are some models with the help of BlueTooth to operate the device as a speakerphone. It successfully views music and video files. In many cases, a modern navigator can even replace a tablet.
