The UST Trekker Stormproof Lighter, formerly by Windmill Lighters, shares many of its amazing traits with the Delta Stormproof and Windproof Lighter design. However, the UST Trekker Stormproof Lighter improves on its predecessors with the addition of an extra large fuel tank giving over 1,000 ignitions on a single fill. This UST Windproof Lighter is the latest design and includes a wrist lanyard. The UST Trekker's larger tank has a fuel capacity of four grams, yet weighs only 2.5 oz. The Ultimate Survival Trekker Storm Lighter's new design makes this high quality windproof lighter only 3.7" tall x 1.2" wide. The UST Trekker Wind Proof Lighter has already proven to be popular, much like other Windmill Lighters, now made by UST. The UST Trekker is only offered in Orange.. UST Stormproof Lighter Features: * Windproof Flame * Piezoelectric Ignition Technology * Water Resistant Rubber O-Ring Seals * Flame Window * Refillable Butane Gas Fuel * Performs in Extreme Conditions * Butane - The Best Choice Trekker Storm Lighter Features: All Windproof Lighters Are Not Created Equal UST Trekker and Delta Lighters have earned the right to call the lighters Stormproof®. While other lighters may claim some wind resistance, none can match UST performance. A. Windproof Flame While many lighters claim to be windproof lighters, but the UST Delta and Trekker lighters can withstand 70-80 mile per hour winds. Their platinum (white gold) catalyzer coil provides continuous ignition of the gas vapors creating a clean, hot flame nearly invisible in outdoor bright light. B. Piezoelectric Ignition Technology The Trekker and Delta Lighter's piezo-electric ignition system eliminates the need for batteries or flints which fail when wet. Piezo is a mechanical system which produces a spark when the lighter ignition is pressed. Independent laboratory tests have found the piezoelectric system to be good for over 30,000 ignitions. C. Water Resistant Rubber O-Ring Seals These lighters have five rubber O-ring seals to ensure water resistance and keep water out when the lighter cap is closed. D. Flame Window A ceramic flame window located on the side of the burner unit of the Windmill Lighter glows a bright, white color when the lighter is ignited. E. Refillable Butane Gas Fuel Refill the Trekker and Delta Lighter easily in just a few seconds with economical, clean burning butane gas. Fuel cans are readily available at most grocery, drug and convenience stores. Burn time of the Trekker Lighter is approximately 300 ignitions at 3-5 seconds duration (over 30 minutes). F. Performs In Extreme Environments These lighters will work in extremely low temperatures (-40 degrees F.) if the lighter is kept above freezing. Simply storing the windproof lighter in an inside pocket will accomplish this. UST Trekker and Delta lighters are optimized for use up to 8,000', but have been used as high as 15,000' by adjusting the flame to a lower setting to maximize oxygen content. G. Butane - The Best Choice Butane gas is the cleanest and hottest burning fuel available for outdoor lighters. UST Trekker and Delta Stormproof Lighters burn at nearly 2,000° F. Butane gas is very economical and widely available in most grocery, drug and convenience stores. Butane gas is also odorless and extremely easy to re-fill while liquid oil fuel used in other lighters burns at a lower temperature, has a strong odor, and is noxious to the skin of spilled during re-filling. PREMIUM BUTANE GAS will provide superior performance in your Windmill Lighter.
