I use the buck urine in fresh scrapes I see that I want the buck to return to. The tarsel gland scent is what i put on the licking branch above the scrape. And as far as the doe urine, I put that on my boots after I have sprayed them with a cover scent and that way the bucks won't smell my trail. Also if I am hunting a trail that I want a buck to follow, I will dip a scent sponge into the doe urine and tie a string on it. Then drag it down the trail I want him to follow right before getting in my stand. The problem with this is you have to be scent free yourself before attempting this. If that buck smells you, all the scent in the world isn't going to help you. good luck
