Great complement to any of the Dent Fix PDR sets. Used when hailing dents for PDR work. After positioning the tool so the varying lines are visible in the reflection of the dent you will be able to determine the approximate size and depth of the dent because the reflected lines will bend around the dent.
DF-DM510DBY yellow version is designed for inside work and works best with shop lights.
DF-DM510DBW is the white version for working outside.
