The Fume Detector app presents one of three safety messages, depending on the current safety status of your boat: "Safe", "Gasoline Vapor!" or "Low Batteries". You can open the Fume Detector app to see these messages in real time. The Fume Detector app can also send these messages as notifications to your locked screen.
A Life-Gard Gasoline Fume Detector must be installed on your boat in order for the Fume Detector app to function.
