Model CMD-1MR-9V The Fireboy - Xintex CMD1MR-9V is a 9V battery powered carbon monoxide detector, ideal for boats requiring additional CO alarm protection and for any boat without a CO alarm.
Carbon monoxide is generated wherever carbon based fuels burn. In the marine environment, some of the major causes are gasoline and diesel engines, generators, and cooking stoves. It is invisible, odorless, tasteless, and deadly. Faulty venting, wind shifts, or CO from adjacent boats may create a dangerous situation, especially in confined areas such as boat cabins.
