The patent-pending Pulsefire is the ultimate compact, lightweight, fully handheld flamethrower that sends a blast of fire 25 feet away with the press of a button. Instantly generate a stream of fire with the press of a button. Fill it like any other outdoor tool. With the system, off, unscrew the cap and pour in gasoline or a gas/diesel mixture. When the battery gets low, take it out and charge it or swap in a spare to keep bringing the heat.
