Interesting you mention the ionizing thing, I presume you mean the ozone generate. Due to another thread here, a member got me thinking about those and I started researching....seems if you are in an enclosed blind,pop-up or box blind, they could be of some definite benefit. Sticking one to the tree above your open stand might not be as beneficial.
Yep thats what I was talking about, wrong word I guess I remembered.
I have NO clue how or why it would work, only that a guy I trust in a box blind (sweat boxes we call em) uses one for bowhunting and swears by it.
I hunt out of a box at times too, and its probably 98% sealed shut but I still have it set up such that I hunt on a particular wind and unfortunatley thats a south wind instead of a north wind. If they go downwind of the box there is always a chance they will alert.
Don't find the need to spend the money to test that unit out though.
