I don't own one, my buddy owns 2...I've tried his and just seem out of touch with what's going on around me...
One thing I do like about them, some guy ramble and call too dang much...At least it keeps them in one place so I can ramble...
I just finished watching a turkey hunt on TV...The hunter belly crawled across a field to ambush a turkey...To me, the excitement is about calling them inside of 30 yards without them knowing you are there, not just killing them...This is also why I don't get hungup on 50 yard groups...It's not about how far away you killed him, but how close...
