The water-buoyant, butane-fueled UST Floating Lighter produces a waterproof flame that also withstands winds up to 80 MPH. The piezo-electric ignition lights up to 30,000 times and works when wet with its zinc die-cast wind guard and lever. The catalyzer coil provides a 2000 degree F (1093 degrees C) flame, and it can be adjusted to provide a proper oxygen mix for optimal performance up to 8000 feet (2438 meters). The Floating Lighter also features an impact resistant ABS plastic, waterproof design with O-ring seal and wire bail for secure closure and buoyancy, and a ceramic flame window indicator that glows a bright white color when lighter is ignited. It has 0.04 ounce (1.2 gram) fuel capacity, measures 2.6 x 1.6 x 0.6 inches (LxWxD), and weighs 0.8 ounces (23 grams) without fuel. It's backed by a two-year manufacturer's limited warranty.
