In finding the best GPS vehicle tracking device, many service companies are curious about what the difference is between types of GPS tracking units. There are three different types of GPS tracking devices which include Data Loggers, Data Pullers, and Data Pushers.
Data loggers include your standard GPS devices available from any electronic store such as Garmin, Magellan, and TomTom. Data pullers include real time GPS devices that regularly send data to a server for real time retrieval and software integration. Data pushers are GPS devices that can be queried on specific time intervals or a set limit for latitude and longitude coordinates and typically include cell phone GPS tracking or mobile phone GPS trackers.
