The fastest trackers are here
The fastest tracking devices available to the public now can track speeds up to 300mph (480km/h), which is the equivalent of a McLaren MP4-12C in a race car.
The latest trackers, which include an infrared camera and a barometer, were unveiled in a new video released by the World Health Organization (WHO).
It is designed to provide a complete picture of a person’s health and whereabouts, and track how much energy is being used, as well as their heart rate and other vital statistics.
The technology is the result of years of research, including the development of a more accurate version of the GPS, according to the WHO.
The new trackers also have built-in Bluetooth to allow them to be used on mobile phones and other devices.
The WHO says the devices have been tested in areas with high levels of obesity, diabetes and infections.
It says the tracking devices are a way to improve health and wellbeing, and to prevent people from becoming ill.
The new devices are being tested in the UK and are expected to be available in the US in the next few months.
A spokesman for the manufacturer said the new tracking devices had been designed to be portable, easy to use and durable, and that the company would continue to work with manufacturers to develop better technology.
