The New 202 GeoTrip Rally Computer from Terratrip. One of the very latest models with GPS, which tracks upto 48 satellites simultaneously, which can give extremely high accuracy typically 0.2% of distance driven. The GeoTrip GPS is far more accurate than the GPS inside a smartphone or most car SatNav devices. Installation is simple with our bracket, either suction to the windscreen or bolt to the vehicle, then connect to the cars 12 volt supply. No more installation is required, but if you require a mechanical probe, you can also connect 1 or 2 in addition. If you connect a probe, then you have the added feature of probe fallback if GPS signal is lost due to a tunnel or similar, then the probe will automatically take over. If no mechanical probe and GPS signal is lost, then the unit will estimate the distance travelled when signal is re-gained. An optional remote display (Part No. T016G) can be fitted and this will show Interval Distance or Speed. Optional remote zeroing unit is available by either foot remote or handheld remote.
