My T2 gets interference with my Garrett unless I go to #3 frequency. Did you try other frequencies with the xp one? I have the Carrot and regular garrett, whites TRX, fisher pulse and the xp and they all interfere with one or another of my detectors and all are quiet with one or another detector. The detectors that can switch frequencies can usually be made to work with about any pinpointer but this is not absolute either. My fisher pulse interferes with the elliptical DD on my Tejon but works okay with both the 5" concentric and the 5" DD coil. However I have not tried shifting frequencies on the pointer.
