So I have on the can calls that says it's the original style. I used it last year and the first time I used it I though it was great. Within 45 minutes of being in the stand I had a 8 point buck come out around 135 yards from me. This was during black powder season. I tried it a few times hoping to get him to come in closer but he never seemed to pay it any attention so I just shot him at 135 yards. I thought this thing was great. However, I tried it several more times throughout the year. I did have a coyote come in once but never saw another deer while using it.

Then this year I tried it on the opening day of BP season and never saw any deer while in my stand. A couple guys about 400 yard away from me had a grunt call and had a buck come in.

Should I keep using this thing or is it doing me more harm than good? If you do use these with luck how do you do it? Do you just do it once and wait and hour or two or do you do it several times in a row or what? Is there some method I should be using?
