Remember when Fido ran away and you spent all night wandering the neighborhood looking for him in the dark? Or that time cousin Timmy got stuck in a tree and no one could find him? Or when you were on a night safari and your light died just before you heard those elephants walk by? If you'd had the Fenix TK51 Flashlight, you would've found Fido in five minutes, rescued cousin Timmy before anyone else knew he was missing, and had memories of seeing wild elephants all up in your business.To ensure that you have the perfect light regardless of your (mis)adventure, the TK51 has 16 flood and spotlight settings, along with a one-button strobe and turbo mode that activates even if the light is switched off. With an insane maximum range of 425 meters and maximum battery life of 429 hours, it's a perfect companion on serious trips where good lighting is of the essence, in your car for emergency situations, or as a handheld light during rescues. The aircraft-grade aluminum TK51 is waterproof up to 2 meters, and has reverse polarity protection to guard against improper battery installation. Even better, it can run on 1, 2, or 3 rechargeable batteries, 2, 4, or 6 CR123A non-rechargeables (although the lifespan decreases with fewer batteries), and weighs under a pound, so you can easily tuck it in a pack or even a pocket.
