IMO turkeys will gobble at most any big noise if not alarmed (shock gobble) and a owl call is a natural loud sound. Some may say like the crow the owl is a turkey predator and thus the turkey will gobble it them, you make the call.
I use a H.S. hoot tube. If your hunting public land be careful as you will educated the birds if you do this before the season starts as a locator. I usually only do it on rare occasions as 9 times out of 10 birds will gobble on their own before they fly down. You just have to be quiet and listen.
I have used an owl call at 0 too early to find turkey just 200 yards from my truck, and he was on the Indian res. So that was a no go...... Just know where your planing on hunting....and the lay of the land...and the property lines.
One of my top locator is the coyote howle. The sharp sound of a yep will make them gobble even in bad weather. I howle away from te roost cause some times if the birds think the tote is nearby, they will be tight lipped.
