I make my own cover scent/scent elimanator. I spray my boots and pants (knees down), each time into a stand. I have had good success, I have had many deer cut my trail without spooking.
However, I do agree that hunting the wind is the most important ingredient to success.

I use the silver Xp by primos I dont know how much it really helps but i don't think it can hurt.

Yes and every little bit helps

I make my own cover scent also and have had NUMEROUS deer come in from down-wind.My largest bow killed buck was only 8 paces DOWN-WIND,with his nose in the tarsal gland from a deer a friend shot and gave me.Tarsal glands in distilled water are devastating to the w-t buck population on my place!!

There are 2 kinds - and most seem to get them confused.

1st are the ones that remove order. These will do a pretty good job of  reducing  existing oder. I know they will do this from using them on things like onion, gas, and skunk.

The other types are those that claim to mask, hide or cover an oder. Work great on humans - not at all with deer and most prey animals that use their nose to survive. They simply process all the oders available to them.

They seem to work somewhat but I make my own.

I totally agree with LostArra.I can't beleive the faith people put into it as well as there scent loc or what ever.When something like 80% of heat and your scent leaves through your head  and don't forget about your breath.
 I only ground hunt and set up my sites.I use the wind to enther.Stay in my favor while i'm there.And in my favor when I walk out.Most hunts don't like the wind but if you ground hunt THE WIND IS YOUR FRIEND.
 I know when I walk out on my deck.Which farm I'm hunting and what site I'm going to hunt.

Prolly need some rose flavored chew or dip, on the stand, in case you come down with the pooties.

Spray your boots and pantlegs and use the wind to your advantage!

I've done both and been close in both cases. I've been close with the wind at my back, as I was in a swirling wind last Sat. I might try the tarsal trick.....pretty obvious. I store clothing in an airtight container and dress in the field.

Spray can't fool a deer. I've had a stone sheep sniff my boot, I've watched wt tail walk along the same path I came into my stand, and on my prints in the snow. I had a grizz 15ft under my stand and didn't know I was there. I didn't use spray any of it. I think it's all about wind.
A buddy of mine is a police dog man, he did a bunch testing while training his dog and it made no difference

spray is a false sense of security.however a little fox piss on the boots will never hurt.the commercial sprays is what I belive your talking about.

Old guy told me years and tears ago...  If there are cows on the farm.. step in a cow pie...  If there are horses find a pile and step in it.

The deer in these cases are "acquainted" with those scents...  I do it when it needs to be done.  I have had deer just walk across my trail and never "blink an eye".

Not me,I dont think it matters what you do except playing the wind in your favor
