Catalyzer coil produces a flame that reaches 2,000°F and withstands winds up to 80 mph; catalytic lighters can continue to operate when standard lighters. Piezo-electric ignition sparks the lighter to life every time, even when wet. Waterproof ABS plastic outer case is impact resistant; O-ring seals and wire bail make sure the lighter stays dry and buoyant. Flame indicator window glows a bright white color when the lighter is ignited. Flame adjustment control lets you find just the right oxygen mix for performance up to 8,000 ft. Easy to refill with butane lighter fluid (sold separately).
