In 2008, he comically caused quite a stir among fans worldwide when he accidentally gave his GPS unit to a pilot who was transporting dogs and equipment to and from a checkpoint, when the race was first introducing GPS tracking on the racers so fans could follow their paths live.

Other top competitors in the Iditarod, like DeeDee Jonrowe and Aliy Zirkle have found this method to work well in communicating with their dogs.

Most recently, Buser was caught taking short cuts and accepting help in the care of his dogs in the 2016 Kuskokwim 300.

While Buser denies intentionally straying from the course, he has been officially penalized by the Kusokwim 300 Race Committee causing him to place last.
