INTRODUCING THE LATEST ADVANCE IN OUTDOOR WATER PURIFICATION!
The smallest, lightest SteriPEN®, the AdventurerOpti, 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. 
It’s a great backup light when camping or taking a night-time walk to refill your water bottle. The Flashlight mode is activated by pressing and holding the single button down for 3 seconds. The clear lamp cover focuses the LED light.
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).
