You have gotten some great advice that I would aggree with.
Time of year, stand location, wind, weather, etc...all are important.
Whe deciding what call too add/subtract from my stand sequence I use a "3 strikes" rule. I will call 3 stands in a row with the same sequence...if nothing shows up I change ONE thing. I might replace a call, change volume, change how long my stand is, etc...
Then I'll call 3 more stands with the new sequence. When a coyote shows up I look at which call was just before it showed up, which call was playing when it showed up and how it showed up...was it charging, trotting, slinking, etc...
Then I'll start running that sequence again...for 3 stands...something shows, it's a winning sequence. This way I can lock onto the local coyote patterns and stay locked on. When they change patterns with the season, I'll be able to get onto the new pattern quicker.
I think a lot of new predator hunters place more emphasis on calls=ecallers and don't pay attention to things that are gking to burn a stand...like noise, wind, movement, etc.
Welcome to the insanity that is predator calling...
