The Retrotrip 3 Classic (classique) is a simple evolution of the Retrotrip 2 Classic and is essentially two trip meters in the same box. One drives the two readouts on the left side of the unit, while the second tripmeter, with its own independent calibration, drives the readout on the right. This enables the user to calculate average speeds using the bath formula which is supplied with the unit.

The Retrotrip 3 Classic tripmeter requires a sensor to operate. (See accessories for options)
