Try to do some scouting pre-season and figure out about where they are roosting, feeding during the day, etc. Look for tracks, dusting bowls, feathers around a natural food source.

In the morning, there is a good chance they will gobble on the roost before they fly down. You will not need to use your locator if you hear them.

Roosting is an everyday activity done by all turkeys. They fly up into a tree everyevening around dusk. This is how they sleep every night. If you see a gobbler roost and you can sneak out of the woods and then set back up close the next morning without him seeing you, there is a good chance at calling him to you. Hence the phrase, "roosted is roasted".

Trying to get within 100 feet is too close, they will probably bust you. They have incredible vision.

Using a blind your first year would be a good idea in my opinion. I got my first 2 gobblers using a blind when I just got started.

Hope this helped,
