I'm not a big fan of scent attractancts. But, I use the cover scents anytime I go out. I will also store all of my clothes in a scent proof back with a dirt scent wafer.

When I head out to my stand, I use a scent pad on the bottom of my boots and spray them with coon or fox urine.

This seems to work most of the time, but you cannot completely eliminate your scent you can only mask it to a certain degree which may be the difference b/t seeing deer or just squirrels.
