BRANTZ Retrotrip Back-Tracker corrector

The BRANTZ Retrotrip Back-Tracker corrector is a popular tool in historic competitions because it does not allow reverse counting. When activated, it records the distance travelled to correct any potential error. A simple press of the switch allows you to subtract incorrect miles or kilometres when you resume your route. This also prevents the Retrotrip from continuing to count until the excess distance has been eliminated. This model is also available in a Plug Kit version, which connects directly to the Retrotrip Plug Kit, as shown in the second photo.
