Gerber Tracking Light
I received my light yesterday afternoon, so to give it a try I went to the meat case at Wal-Mart hoping to get a pack of bloody beef liver, but the best I could find was a pint of chicken liver. I bought it thinking that blood is blood. The blood in the liver was watery. I took it out in the yard and made an 8 or so foot stream of the liquid. It had just finished raining on the grass. The light is basically four little blue lights and four little red lights. Using the light I could find no evidence of any kind of blood trail. I'll try and get some beef blood tomorrow and try again.
