The Brantz Dual Sensor Switch is a handy piece of equipment that allows you to connect 2 sensors to one tripmeter, should the terrain change mid rally you can simply flick a switch to bring in to use the alternative sensor more appropriate to that terrain.

This is essential on long distance rallies where parts of the car may wear and possible break such as speedo-cable. You will not loose any of your previously recorded measurements - but don't forget to adjust your calibration figures!
