this may be coincidence, but....last season, first hunt, we had my DSD jake out and had several birds come in, one as close as 6 yds...we were bowhunting, without a blind, so didn't get a chance to even draw with that many eyes...they wandered off after a great show.
The next weekend my friend went without me, he set up his avion jake as hen, same field, different location.....saw the same birds, but the all hung up at about 60 yds.
The following weekend I went alone, with the dsd jake, had 3 Longboards come in and strut circles around the jake....one went for a ride home with me.
I can't say the dsd's sealed the deal, could have been they liked my call better....you just never know with turkeys.....and trust me, I've had days when they won't even look at my decoy....
