RE: Have you used any of these scents?
I have used the Tinks and the Active Scrape. The active scrape came with one of those drip bottle thingees. The drip bottle didn't seem to work right...ever, but the active scrape scent seemed better than average at attracting deer to my mock scrape.
Tinks works for me for a limited amount of time. What I have found is that everybody in my area uses it and the deer begin to associate humans with the scent.
