You are officially addicted!. I don't change the sound at all when I'm hunting "shared" ground and I see a coyote coming in. I stop them with a bark, or quiet "hey" AFTER they are in the scope or the shotgun bead is on them. Don't pull their attention to you if you are not ready to pull the trigger. You can do everything right and still not kill, happens more the we like to admit.

Bro just keep grinding on… take the advice you been given and apply it and you will develop your own style and methods

In my opinion shutting off the e-caller and lip squeaking will get you busted more times then not.There NORAD radar system will pick you out in a second..
Just somthing I've learned hand calling the last 45 years when they heading in the right direction don't do anything different,when they get close,most of the time silence is best.

I agree with all of the above tips if you have them coming go to less volume if they stop try a coaxer sound that has worked for me at times. Keep after them and good luck.
