The Nebo Illumatrace Blood Tracker is a hunting flashlight that helps you follow a blood trail after a shot. Its patent-pending Illumatrace mode uses alternating strobes that make blood stand out against grass, leaves, soil and rock, with three strobe rates (S1, S2, S3) to suit your eyes and the conditions. A mode selector dial switches between the 150 lumen blood-tracking mode (about 3 hours, 75 m) and a 170 lumen white mode (about 2.5 hours, 80 m) for walking back to camp. It is waterproof and impact resistant, rechargeable by USB-C, and runs on a 4,000 mAh Li-ion battery. It is about 190 mm long and weighs about 380 g. In the box: flashlight, detachable lanyard, removable belt clip and USB-A to USB-C cable.
