Just an FYI from another hunter who has been playing with this stuff for a few years. I have had mixed results on the trail cams but still working on my technique for set up and so on. I will be trying the "wicks" technique beginning next month through the season with the few cameras I have and see what happens.
I really like the idea and how easy it is to freshen up the wick.
Here is my "tip of the day" for those who care:
There is a product on the market called, "Cold-Eeze" that you can get in any drug store. It is some sort of natural spray that from my results seems to limit or shorten cold effects just as described and I use it when flying to keep my immune system in check - well here is the better news!!
The pump spray top fits perfectly onto a bottle of Smokey's lures and makes for a sweet delivery system that is virtually scent free. I was fumbling with surgical gloves and Q-tips to make my mock scrapes and now just a couple pumps and, whola, all good.
Obviously you want to clean the pump up a bit before using but I have not noticed any decline in response to my set-ups since using these due to residual scent from the cold eeze and it makes for a simple method of letting off a controlled amount of scent while heading into the stand or from the tree itself.
