Mobile Mapper Devices

Mobile Mappers, also known as GPS trackers are small electronic devices which provide accurate positioning of any person, vehicle, or item within a certain range of their location. There are two types of GPS trackers available in the market today; analog and digital. Both the series gps and mobile mapper devices have their own advantages and disadvantages. The main advantages of using this type of surveying or mapping equipment is that they are small and light weight, and can easily be carried from place to place.

Digital GPS mappers are more dependable than the analog ones as they usually come with a small LCD screen to show the position of the device. However, the digital mappers usually do not have the same level of accuracy as the series gps models. The main disadvantage of using this surveying or mapping equipment is that there are no external power sources required and they cannot function well in cold weather conditions. They can only function up to about -40 degrees Fahrenheit.

Mobile GPS devices are powered by rechargeable nickel cadmium batteries. The battery is normally installed in the handheld unit via an electric connection or an USB cable. The units have an onboard charger which can be plugged into a cigarette lighter outlet. To monitor the position of a person, the user has to take out the battery and insert it in the GPS receiver. As the receiver is in constant contact with the earth, the information is displayed as soon as it registers a signal.
