I don't reckon there is anything unethical about using decoys, afterall they are legal. But i do feel sorry for those hunters that have gotten into turkey hunting in the past 10yrs or so. They have been inundated with adds & videos that push decoy use & therefore think thats the way u hunt turkeys. Boy are they missing out on the plottin & scheming. Missing out on the ridgetop chess game, dueling with an ole bird. I couldn't stand to simply put out half a flock of dekes & sit & wait! Now there is a time & place for decoys, but not all the time, anyplace!
As for electronic calls, they are unethical since they are illegal, at least in most places they are. Electronic calls would b like going to hear a band play & the conductor pulls out a radio! JMHO!!
