personally i would never use one because i dont think that it is ethical to use just because it works to good. Someone is probebly saying "if there is a golf club that makes you hit farther why dont you use it?" well the fact is even there is limits in golf clubs and i think that for hunting being able to use electronic calls is the limit/unethical (in BC, where i come from, you have never been allowed to use bait/electronic calls but the government has said that this year we can use electronic calls for predators) i just wanted to hear what everyone else thought
