RE: USING DEER DECOYS IN PENNSYLVANIA
Yes and No.
Yes it is legal to use decoys during archery season in PA but, no, I have never used one of the ones you mentioned. I tend to prefer the small, collapsible foam Featherlite bedded doe decoy. Easy to tote around and the 3 dimensional affect is quite convincing.
My experience with decoying in general has been hit or miss. I haven't quite figured it out entirely yet.
