I know there are alot of haters to scent covers on here, not that I am a firm believer they work my self but here is something to ponder. I was at the doctor s today reading a field and stream mag when I came across a research article. The test was have a search k9 German Shepard find a man out of 9 boxes, the guy went and sat s few seconds in each box before picking one. 1st test street clothes the man was found in 14 seconds next one the guy took a baking soda bath the man was found in 19 seconds. 3rd the guy to a bath non scent soap and put clothes on that were locked up with a ozone generating unit the k9 had to search every box twice before pin pointing the man at 42 seconds. The final test the man took a shower non scent soap and stayed in a box with a o zonic mounting unit again the k9 had to make two pass thoughs before letting out a half bark at the box the guy was in. It was a im not positive bark. At 50 seconds. Now I will not go buy all these things and will do my best to hunt the wind but I did find this study interesting to know that there might be something to give me almost an extra minute to shoot.. this study was meant for deer but I found it wound relate more to a coyote since it is a k9 family member.. I also know the dog is a lttle differnt it said it went and searched every box before picking one and a yote will react off first instinct more but it was just interesting to me..
