In regards to caller placement…distance probably not as important as wind direction….some cover/concealment for you is second. Coyotes can keenly smell and see. Consider those two things first and place accordingly.How far do you sit from your caller? I'm typically 60-80 yards. Should I be farther? Does anyone sit their caller right next to them? Seems like that could draw unwanted attention to your position, but also would avoid exposing yourself when you walk out to place it.
