I call for a minute or so on the first series and then pause
for a minute and call again and take a longer pause for
coyotes. For fox, coons, or bobcats I will play the ecaller
for longer periods of time with short pauses. I like to
start off with a distress call and if nothing shows I switch
to coyote vocals. A mix of sounds seems to work best for
coyotes for me.
