The smallest, lightest SteriPEN, the Adventurer Opti, uses a revolutionary optical eye to sense the water. The patent-pending technology ensures safe use and provides purification in even the coldest of waters. The new optical sensor doubles as a convenient LED flashlight. The AdventurerOpti retail package includes 2 non-rechargeable (disposable) CR123 batteries and a neoprene case with belt loop. Device works with containers with minimum 1.75 in. diameter opening (ie Nalgene wide-mouth bottles). The Adventurer is half the size of the SteriPEN Classic. Because it's fast (48 seconds for 16 ounces), light (under 110g/4 oz), easy and effective, it's perfect for hikers and campers who value powerful products in small packages with no loss of effectiveness.
