I tried posting this question on the Outdoor Gear section a week ago and got no hits. I know Bowhunters all have to have skills in blood tracking and I am always looking for ways to improve my skills. I recently have been seeing different LED lights that claim to be an aid in blood tracking. At first it was any red LED light...now it seems to be growing. I was in a store that had an ad for a Gerber and *Look and Compare* display. I was wondering if anyone has tried any of these? Are they strictly for use at night, or do they also help in the daylight? Strictly a gimmick? Any input is appreciated, as any comments on person experience. Thanks in advance.
