I am a huge fan of Randy myself and own all his video's and DVD's. The guy pretty much taught me how to hunt coyotes. But the howler I use is the Crit'R'Call song dog Jr. They're louder and a bit easier to use than Randy's howlers IMO. And I can match Randy note for note on every sound he makes with his howlers. Since learning how to howl, And what the different sound meen, and how to make the different sounds, I've doubled my success rate.
