Hunting any game with a call can be tricky. You either do it right and experience success or do it wrong and wonder why you haven't seen anything. I chose the hard way. Try it myself, how hard could it be, right! Wrong, I went from not using a call and seeing animals to using a grunt call and seeing nothing.
The deer probably thought I was a mixed breed between a hog and a buck that hadn't seen a doe in 6 years. Luckily that was over 12 years ago, and I have picked up several tips. I am not saying that every time you call a deer or elk comes running to you. If accessible, we would not call it hunting.
If you want to try using calls, I recommend getting a video and listening to some professionals on how they call deer. Not only how they call, but when and what calls to use. For instance, you don't want to use a grunt call when the deer are not even in pre-rut yet, or bugle for elk two months after the rut is over.
Deer are susceptible animals with a keen sense of hearing. They communicate whether we want to believe it or not. Sending the wrong signal to a deer will spook them almost every time. If you are getting into calling or want to polish a few rough edges, I recommend a kit from Primos. The kit consists of a Trophy Grunter 6-in-1 grunt call with deep throaty grunts to do bleats and a video that is 60 minutes long and is focused strictly on calling deer. Big Game Pro Shop has this kit with both the call and the video. The video is one of the best I have seen for calling deer.
