Rett Moore of Hot On The Trail, LLC located in Valdosta, Georgia sent me some of their DeerCON scent dispensers (www.deercon.com) to try out in the field. A few years ago, I tried to convert one of those home scent fans (I think made by Oust) for hunting use. Well, needless to say, I was not successful. Those things are truly made for use inside your house and I could never get the fragrance smell it came with out of the containers. When I received the DeerCon fan, I was already familiar with the concept.
The concept is to pour some deer lure on a pad and have the battery operated scent fan blow it out in the woods. You place the fans out in your hunting area before you hunt and turn it on. I tried them in the field and you can see me set them up in the video below.
The scent fan worked as advertised. I deployed them in my downwind path so deer would smell it instead of my odor. You can see a fawn come right up to it. That same hunt you can see a buck come downwind of my location and smell the scent and not me.
The only improvements I would suggest is to paint them orange, because they are hard to find in the dark, and install a toggle power switch. The push button kept getting pushed while unattended in my hunting bag. I would then notice the motor or sometimes the smell and realize it was inadvertently turned on.
In conclusion, I will definitely use them next season and if you use deer scent I would highly recommend buying a couple for your hunting ventures. You can buy them at www.deercon.com.
