The only deke better than a DSD is a real live turkey LOL!
I posted in another thread about dekes....they are not fool proof and don't work all the time. I've had mature paint brush toms turn tail after seeing a jake deke in a non dom posture with a hen deke nearby. Heck I've had full blown toms turn tail on a single hen, but more often than not day in and day out, you're going to kill birds more often with a single hen non looker type deke!
The tom/jake dekes do work....to a degree. There's a time in the season where they work REALLY well, when the birds are just coming out of winter flocks establishing dominance, well if you call winter winter in Mississippi LOL! There's nothing like early season bird hunting with a strutter/jake deke in hand! It seems to slow down until they hen up again but works to a lesser extent.
I used to be a feather flex guy when they came out, and than delta picked the design up with a light rubber version. Typically when I hunt with my old man I'd guess 70% of the birds would skirt my dekes and go to his jenny vanes (silhouettes). That was the tip off for me on bad dekes. Being a traveling guy its the ONLY reason I don't carry the DSD, though I'm contemplating getting one for the home in MN for our hunt this year.
I've ditched the jake/strutter deke and went back to strictly a single hen. Dad told me this in my early days, it only took 25 years to relearn it lol. I'll be honest, I really HATE sitting in a blind all day for birds. I've done it successfully but to me its not as much fun as running and both with the black powder and the longbow in hand.
I will say when they come in doing the mean walk ready to blast your tom/jake strutter....its the highlight of turkey hunting career. I spend more time cracking up than trying to shoot when it happens. It just seems to happen so infrequently that I don't believe traveling and than carrying it is worth it. It does bring in hens like you wont believe! This is when it really seems to work well when they're henned up, but for me at least the toms generally hang up out of range when coming with their own hens. They end up skirting instead of coming in and flogging.
By the best deke you can buy, or don't by anything! They only keep getting better and better!
