Even after being shot by a modern hunting rifle, deer, elk, moose and other big game maintain an extraordinary ability to run for long distances, compounded by the ensuing adrenaline surge. This phenomenon results in hundreds - even thousands of game animals being lost every season. Don't let your next hunting trip be ruined by dashing game - keep an iProtec Blood Tracker in your rifle case or outdoor pack at all times! Fortunately, runaway game animals leave behind a trail of clues in the form of drops of blood. Depending on the wound site, however, these tiny red beads can be scant and difficult to see - especially in low light conditions or against similarly colored ground cover. But the iProtec Blood Tracker makes those subtle crimson trails pop, keeping you on the right track - hot on your prize's trail. The Blood Tracker employs a high-powered LED in two distinct lighting modes: white light and red/green light. When the latter is activated, the mixture of green and red light creates an amber-like color. Amber light causes materials that are truly red - like blood - to clearly stand out from materials that merely have red in them, allowing blood to be discerned more easily than with the naked eye alone. Once you've found your fugitive game, use the 120-lux white light to find your way back to your truck, camp or other base location. A 4x adjustable zoom allows you to concentrate light on specific spots or spread the beam over a wide area. The Blood Tracker boasts tough anodized aircraft-grade aluminum construction that can handle even the harshest outdoor conditions, and a steel belt/pocket clip that makes carrying it comfortable and convenient. At 4 1/4" long x 1" diameter, it's easy to wield and won't take up too much precious, limited space in your outdoor gear. Ready to start tracking right out of the box, the Blood Tracker includes two AA batteries. At this price, there’s no excuse not to make the iProtec Blood Tracker part of your regular hunting gear. After all, it’s much more costly to lose that giant buck!
