Vapor detectors protect you from the hidden threat of carbon monoxide, fuel vapor, smoke and other dangers on your boat. West Marine carries a selection of detectors and safety alarms for your boat. CO detectors should be installed in areas where poisonous exhaust may pool and concentrate. Fuel vapor detectors will alert you to dangerous fumes your engine blower wasn’t able to blow away. Smoke detectors will let you know the moment you need to grab your fire extinguisher, and fire detection system monitors give you at-a-glance fire notifications from detectors installed in multiple locations on your boat. West Marine carries all these so that you can boat without fear of invisible dangers.
