The UV - Dot Kit works fantastic with our UV3 scope. Comes with four colors - Green, Yellow, Orange and Red The ultraviolet light emitted from the light cartridge will illuminate these fluorescent sticker dots. Most dot kits come with only one card of dots. As serious target archers we know that's just not enough, that's why our dot kit comes with 4 cards full to the max with dots, circles and crosshairs.
