1) Quick description

RfLapCounter is a complete timing system for Karting that allows to do training sessions or races.

It is intended for outdoor and works in every kind of weather (sunny or rainy).

Operating mode : When the kart crosses the magnet bar/strip, the transponder sends a RF signal to the decoder located on the edge of the track.

                                  The lap time is then transmitted to the software (PC) or application (Smartphone).

                                  Several 'USB' or 'Bluetooth' decoders can be used simultaneously with a single magnet bar.
