The first Gerber Blood Tracker Light was introduced back in 2005. Since then, Gerber has updated, enhanced and greatly improved its proprietary Trax Technology, which makes blood stand out and become clearly visible against the assorted backgrounds bowhunters encounter in the bush.
One of the big improvements in the Trax system is the addition of a third color, cyan, to the unique mix of red an blue LEDs of the original. The new amber LED enable the hunter to and the other shade of red that appear naturally in leaves and weeds. The new Blood Tracker is considerably brighter than the original Gerber Carnivore and Carnivore XP tracking lights.
Using the Gerber Blood Tracker Light is the best way there is to make sure you never lose another game animal because you were unable to pick up a blood trail. The red, blue, and cyan LEDs combine to help the human eye distinguish between the deep red of blood and the more subdued natural red hues found in the bush. Blood stains show up as a bright red color under this light instead if in shades of grey as with ultraviolet trackers.
The Blood Tracker features an integrated Gerber Gator-Grip handle for a firm, no-slip grip even in rainy weather. It is powered by four standard AA batteries. The best operating distance is approximately two meters from the target. Overall length is a compact 6.88 inches and the carry weight with batteries is only 6.7 ounces.
