Im not sure but ive done alot of lamping and never really seen folk chase stuff before letting a dog out thats not really how it works. U spot ya stuff stop motor let dog out follow on close enough to keep stuff in the beam but not to effect the course. I have seen some people turn particular stuff with a motor but never seen it coursed then a dog chucked out.
ill walk or drive im not fussed but ill tell you one things youll see more dogs jack bieng run out of a motor than you will on foot 110% fact
