If you want that Buck or Doe 10 feet below you scent is very important..If you use a rifle and shoot them at 75-200 yrds then eat chilli, smoke that cigar...but scent dose make a differance exspecialy when you get into older and wiser deer....I alway put dirt,leaves and twings from the area I huntin my tub(replace every year)I put my hunting clothes in its free and it works,the only other thing I do is shower with scent free soap and spray it on my bow,boots,gloves and hat...
