"When I first bought my GPS tracking unit, I installed it in one of my vehicles without telling anyone, I had suspicion that my employee was milking the clock. The first day, my employee clocked in and then left, but he went to his home and stayed at his house for about four hours. When he returned to the shop, I asked him if he made any unauthorized stops. He told me no he had stayed on the route. At that point I showed him where he went and how long he stayed. The tracker saved me four hours of labor, on that day. Another situation is when a State Trooper came to the shop and stated that one of my trucks had been in a hit and run with a vehicle. He had a sworn statement that someone had seen my truck hit the other truck at a certain address. I used the tracker to find out if that vehicle was in that area. The tracker showed that my truck had not even been close to that area. No evidence of a hit and run and the tracker does not lie."
