My brother and I have a pop up blind that we plan to use and have zero experince in calling turkeys. All advice will for first timers will a huge help!
A turket is not too smart, but he knows every leaf in his territory. A nice new pop-up blind suddenly appearing will cause him to shy like a cow looking at a new gate. I much prefer full face net and hand camo and disappearing into natural cover. Don't fidget or silhouette yourself.
If you're going to call, consider a decoy to give them something besides you to look at.
