wearing rubber boots to control scent is showing that you don't know much about canines. We loose 3 trillion skin cells a day, they can smell that stuff, like a blood hound, but not as well as a blood hound. A hound can follow the scent of a child in the trunk of a car that went down a road or highway up to a month later. They can tell from watching the dog if the dead or live person is in the trunk or not!
Rubber gloves, boots make you hot, you sweat more, give off more odor. Go with a good gortex boot, leather gloves or no gloves w/not contaminated hands. Forget the kneeling pads for scent control,we have no scent glands on our knees!
