Love the new tone for foil as its the hotspot for thin gold rings with nice stones..Watch the large target alert as it went off on two seperate quarters right on top. Perhaps mine is set too sensitive but certainly not a plus..which is supposed to be improved....Was able to get very close to a fellow with a CZ7A with the CZ3D...on previous CZ's I used one CZ would blow another out of the water with cross talk even at good distances..So Indeed a CZ3D is a different beast from previous CZ's....
