Owl,crow etc.are common in ur area so turkeys are less likely to gobble,The calls u have a duck goose will do just as fine as a owl ,crow etc..I personally dont use any locator calls.Cause the area i hunt they r constantly gettn those calls thrown at them.And if they do work its only for a short time before they get use to them.So i will slip in when its gettn dark when they are roosted and give them a quick shot of a hen yelp and fly up cackle.This always seems to work,even on stuborn birds.Or if u can get into the woods in the morning as its getting light before your hunt season,Just listen they will give out there location on their own!With a gobble,more likely for them to gobble when its getting light then dark.Especially on public land!This is from my experience and
This is what works for me.
Good luck to ya and have fun....
