Just got my f2 I tried it out in the front yard and all it does is chatter . Changed batteries check coil connection but nothing fixes the issue . Took it to the beach today to see if a place with no electronics would resolve the issue but still doing the same thing . Tried low sensitivity and discrimination and I am out of ideas . Anyone know something to try ? I live about 20 min from Kelly co where I bought it was thinking about stopping in tomorrow and see what they say
