Perfect for measuring baseball pitch speed, training, and speed checks. I bought this for my son, but he didn't use it much, so it's only been used a few times. This is a used item. The main unit is in relatively clean condition without any noticeable scratches, but the box and instruction manual have scratches, marks, dirt, and dents due to long-term storage (see photos). The accessories are all shown in the photos. Please understand that this is a used item before purchasing.
