My uncle & brother swear by the box call, cause it really carries. I use my regular slate call and just "hit it" a little harder.
I have acrow call but have had little success, primarily because, like others , I'll have apretty good idea where they're at from scouting before my season arrives (Wisconsin is 5 days only per permit). when I'm running and gunning after a few hours into the day, I just go back to my slate.
Like said, any noise will cause a shock gobble, but where I hunt, they only consistently shock gobble while on the roost. Once on the ground, to get any response, you better sound like a turkey
I bet you'll get another 10 posts after this, every area and terrain and turkey sub-species are a little different. Get to know your area, even on public land, and you'll be successful....even if it takes a year or two.
I know it's mundane and always said, but be careful on public land. Hope and pray for success but always assume another hunter is right there....I know, you're not an idiot, but it's still good advice. Take care and good hunting
BTW, I live in
northwestern Wisconsin, so the turkeys are similar. When I move from Appleton, turkey hunting was still just for a few "hardcore" hunters. It's really exploded in the last 5-10 years. Also, I've hunted over there before and that part of the state gets hit hard. Pay attention to everything and learn from year to year and you'll be successful!!
