i agree with firstbow about staying away from scents but i dont even use them in the rut . i think they are all usless for one simple reason. they are not fresh. bacteria sets up in urine almost as soon as it hits the air and it goes bad. for example my buddy this year wanted to buy standing estrous for 40 bucks a bottle and i told him he was crazy so what does he do? he buys it and guess what yea its a pretty yellow sealed but he opened it one day and the next day it was dark brown and getting darker every day after that and that is the bacteria breakdown that makes it stale and usless. the best thing to do is do your homework early in the year and find where the deer are and where they are moving through and spend the money for scentlok and eliminate your odor and you will be bagging deer without contaminating the area with storebought junk. deer are nervous enough as it is and your only making them more nervous by adding unfamiliar smells to their area. what scents are is a marketing tool for companies to sell a product but i have never had a scent work and i have hunted for 25 years and have taken some nice trophies and it only got better once scentlok came out.
