I have been using areas off a heavily travelled trail to test different attractants. Each new attractant I try is set further down the trail than the previous from the bedding area. I leave a trail cam set up on the attractant for one week. I rated each attractant by:
1. Number of deer showing up;
2. Number of adult deer;
3. Buck to Doe Ratio; and
4. Longest Time spent at attractant.

Here are my results so far:

Trophy Rock: ($14.99) 16/15/7:8/6min 3rd one tested and still has a lot of activity.
Deer CoCAIN (Black Magic) ($7.99): 37/37/5:32/12min WOW! they come in and stick around for quite a while.
C'mere Deer ($19.99): 8/0/0:8/2min 2nd one setup and visits dropped off drastically after trophy rock setup.
Salt Lick ($5.70): 32/16/2:14/1min 1st one setup and least frequented since the others started.

I just set up a trail cam on a product new to me - Advantage 360 Supermaxx ($9.99)

Questions:
1. Has any of you done any type of study on different attractants in your area?
2. Do you feel the criteria I set up is fair for rating the attractant?

Thanks for your input.
