The Distance Tracker 2000 was first seen in BFDIA 5c, where Needle uses it to see how much longer they need to walk to arrive at Yoyle Mountain. She sees it says 70 feet left, and Yellow Face and Needle then cheers, thinking they are that close to Yoyle Mountain. However, Coiny points out that it was actually the distance to Evil Canyon, and the real distance to Yoyle Mountain is 2761 miles. Shortly after, W.O.A.H. Bunch falls into Evil Canyon and the Distance Tracker 2000 is never seen again.
It is unknown if the Distance Tracker 2000 will make another appearance in another episode or season of BFDI.
