I had bucks hit my mock scrapes/drippers, just the numbers of them droppedalways when a dripper was added
and I played with all sorts of things too, I used to take a fishing pole and a scent drag, so I could cast it out in several directions and pull it to me, in hopes of making a scent free trail
I also tried using a sling shot and putting out scebnt that way
But to be honest, I have my best luck just trying to be scent free as possible and not using scents at all anymore
saves me a bunch of $$ too, and I have more bigger bucks in range now than ever
but then again, I just have more older deer now than in the yrs past between, the antler restrictions and well me bing a prick chasing everyone I can off the borders cheating(hunting in a NO hunting zone)
so I cannot say for sure that NOT using scents has been my winning deal, but it still saves me $$ not using, and I am happy LOL
best of luck, I look forward to a pic of this buck and you together this fall! a well earned trophy for sure!
