The UView Spotgun Jr./UV-Phazer Kit's capabilities start with the Spotgun injector that inputs a precise amount of dye into the A/C system, without overfilling. The Phazer's 18 UV LEDs then take over with a concentrated single beam of light for brighter dye illumination at leak points. Also included in the kit are two dye cartridges that translate to 10 applications, R-134a and R-12 system adapters, UV enhancing glasses, dye cleaner/remover and service stickers.
