My opinion only but, nothing can replace high quality management, operators and excellent training for all. Systems like shock watch and other truck monitoring bells and whistles are costly to purchase, install and maintain. In a well run facility they are unnecessary. In a badly run facility, blame must be assigned it would seem. The trouble is the badly run facilities, by definition, can't afford these kinds of add ons and, even if they could afford them, they wouldn't spend the money. These systems are not cheap and the justification figures presented by suppliers are dubious at best.
