The Miracle Care QuickFinder Deluxe is an electronic, safety nail clipper that is excellent for detecting the quick by using patented QuickSensor technology. This sensor sends visual clues when it is safe to clip the nail. Green means safe, yellow means caution and red means stop. When clipping, turn the device on before you place it around the nail. Face the sensor lights towards the paw, bring the clipper to the base of the nail so it may locate the quick, and then slowly guide it near the tip until it lights up green. When clipping your dogs nails, always be sure to keep Quick Stop open and ready beside you in case of an accident. Many dogs are impatient with the nail clipping process and tend to move frequently.
