Review on Elitech HLD-200: Advanced HVAC Refrigerant Leak Detector & Automotive Gas Tester by Kurt Ahui

bought to find a leak in my car's air conditioning. The device detected a refrigerant leak in the air from the air vents in the car, indicating the leak was in the dashboard. The device has a green light to indicate it's working and sounds very much like the old Geiger counter. beep beep beep is a continuous beep and when it detects the LED turns orange and the beep becomes almost continuous. I tested this by having him smell the refrigerant coming from my car's charge port. This thing also comes in a shiny aluminum case (mine at least) will be updated if I use it again any time soon!
