The Equipment Threshold Hours window is used to set up a discount schedule for each piece of equipment you own, based on the number of hours the equipment is used per day. For example, if you want to offer a discount for your owned equipment after eight hours of use per day, you would enter '8' in the Day length threshold field. If your owned equipment is used more than eight hours per day, then the discount would be applied to any hours over the threshold of '8' set here.
