Got my FX3 on Thursday, went out for the first time on Sat, at the first stand I used both speakers, started with a howl, went to lucky bird (should be titled "unlucky bird") and immediately switched to the crow party. Had a coyote respond within 10 minutes. He stopped about 50 yards out and took off, in the opposite direction, couldn't figure it out until I saw a bunch of illegals coming up the wash.
Think I will continue to use both speakers.
Mike - You may want to contact the Border Patrol here in AZ, seem that your new caller is very capable of not only calling in 4 legged coyotes but two legged ones as well. Could never figure out why they call the "guide" of these illegals coyotes, seem a great injustice to our 4 legged coyotes.
