This was with the TX500/CS24 Caller. I don't know if it will work on a spitfire but it works flawlesly with the tx500. Field tested today. No coyotes seen to try it out on but I turned it on at every stand and it worked up to 50yds away (I didn't put the caller or the decoy any farther than that).
The Mojo batteries are what powers the decoy. All I did was remove the on/off switch, couple the decoy to the caller with the 3.5 male to male cord, and switch the controller to the latched setting.
