Cutter,
I can assure you that the Garmin is reset each time I turn out. When we stop the truck to unload the dogs, I collar the dogs, then I calibrate the compass, start new hunt, and mark the truck location. There is no travel time included in the 25 miles. There may be an occasional short ride on the Mule, but I would say that accounts for less than a mile or two in a hunt tops. These dogs just stay busy, ~25 miles per hunt ~5-6 mph.
Contest weekend one of these dogs covered 50+ miles in two days of hunting, the other did a little over 45 miles. That weekend was hard on them, but they rested a few days and were ready to do it again.
Circle C,
Are you going to each dog collar on the dog sceen, and resetting the trip for them individually? If not, it is not covering just the "drop" of that dog. It would be covering the travel route since the collars were turned on. Again, I don't want to come across harsh, but 25 miles in this heat is rank to say the least. I can take pics of the screens if it will help. I often don't explain myself very well.
