The unit houses a patent pending heating element which utilizes household electricity instead of the conventional way of using expensive propane. A heavy duty powercord with a safety breaker built into the lug is attached and operates on standard household current of 110 volt. Easy to use the unit manipulates tap water and dish detergent for an approximately 8 hour process, at the end of which, your trophy is ready to be rinsed off and mounted. Temperature is held more constant with the Buck Boiler than when using propane to make damaging the bone structure of the trophy less likely.
