I think everybody has their own little quirks when calling foxes,but,the basics are the same.I personally will change what I do on any given night,but,I almost always leave the lamp on the fox,unless it is really cagey,then I will sweep the field every 20-30 seconds.I only really use my own mouth to squeek,or,I might(rarely)use one of the long range calls from time to time.Just concentrate on the calling,as this is what gets them in,don't worry about doing it too loud,or on occassion very softly almost like a mouse,this sometimes brings them in so fast that you have to make a noise to stop the
