From the manual:
Laser Targeting Device (Models 85006 & 85007 ONLY)
This bottle jack has been fitted with a laser targeting device. This device is designed to assist the operator to properly position the saddle of the bottle jack under the lifting point on the undercarriage of the vehicle being lifted.
I feel so inadequate now. None of my old bottle jacks have a "laser targeting device". How have I gotten by all these years?
Hmmmm a hammer with a laser. That way you would know that you are about to smack your thumb instead of the nail.
