RE: Blood trailing "AFTER DARK"......
Coleman Lanterns are best with a back up of peroxide.
This year I tracked one liver hit and one gut shot animal. Mine was the liver hit. Though I am happy and proud with my success, I must admit the hands and knees tracking was EXTREMELY exhilarating and very rewarding to say the least.
Here in the Pacific Northwest I have not used Coleman Lanterns because it is usually very dry and I consider it very dangerous. I am a firm believer in Murphy's Law and it would be my luck to trip and start a forest fire . . . but have used them in Ohio and PA with great success.
