well one more thing, travel following the long upper arm of the K or go west, always by sweeping a metal detector, u might start finding pieces of metal that might look not valuable but they will be pointing a directional mark you keep following that direction as u keep finding metal parts or any arrowhead rocks pointing to the same direction and they must to be on a same lane, that will tell you were to go, if you find any bigger item even if not value, let us know so we can keep trying to guide you. but form there you can also from the bird mark spin around the area your detector and if you find any metal at all, keep going that way starting from the bird to your 1st piece of metal regardless of value. and if you find another metal by keeping the same direction from the bird, that means you are doing great.
