RE: wat type of cover sent
You should use something natural to your hunting grounds.Cover sent will only help a little. If a deer is down wind, they will smell you, needless. I dont bother with cover scents, other than throwing a natural earth waffer in with my hunting cloths container.
In the past, ive boiled down leaves from my hunting areas to make a condense spray. Ceder works the best. That is if you have ceder trees in your area.
