A little scouting, and less calling would be my suggestion. You can't call what's not there. Check for tracks in all the sandy trails. Moving 200-400 yards is way too close, 1/2 mile or more would be better. If you are just after bobcats use the decoy every time. Try to get close (stalk) to where you think their home is, before you call, and then stay there a minimum of 45 minutes. Take something soft to sit on, or you will be moving around, instead of being as still as a rock. Most, don't know how important, just sitting perfectly still is. Being slow and quiet going in and out is just as important. Just one last tip, when you think it's over, look around when you slowly stand up, sometimes you can see things that you couldn't see sitting down.
