The PathFinder Omega Electrostatic Dust Print Lifter device has been designed to eliminate the need for the wire connecting leads normally associated with more conventional electrostatic devices. Compact size allows it to be carried easily within the crime scene field kits. The PathFinder Omega is powered by a 9V battery. As a safety feature, the PathFinder Omega device is designed to only operate when placed correctly on the earth plate or other suitable conducting medium and when there is a suitable insulating medium between the earth plate and the high voltage electrode. Provided in a carrying case that may be worn on a belt. This device will lift dust prints off floors, fabric, doors, chairs, carpet, concrete, tables, paper products, metal, counters, and plastic.
