Qstarz BT-Q818XT

An eXtreme GPS Receiver

The BT-Q818XT supports 10Hz GPS update rate, giving very high resolution position information for high speed sports requirement. 10Hz helps to decrease the annoying display lag time and improves tracking and distance measurements especially if moving on curvy route. As well as the 3-level switch to easily switch to 10Hz high speed more or 1Hz normal speed mode

While most of GPS Receiver only provide a 1Hz refreshing update rate, that means they send out the location once a second. This Qstarz BT-Q818XT sends the location information 10 times a second.

The main benefit for the increased update rate is for users that require precise positioning, or if you are recording data at speed. This will give a much smoother curve when the data is reviewed, and will of course allow for a much finer analysis of your speed at each trackpoint. At 60MPH or 100KM/H you travel one mile/KM in one minute or about 88 feet  (or 27 meters) per second. This means that a conventional GPS will send your position once every 88 feet (or 27 meters). The Qstarz BT-Q818XT will send your position every 9 feet (or 3 meters). You will now be able to analyse acceleration and braking much better.
