Hello, my name is Gabo Castelo from the YouTube channel Cazando la Historia, last April in the state of San Luis Potosí, México, crossing a river, my equinox 600 gave me a slightly confusing mark but between the sweep a good mark was present, I decided Digging and after removing several nails from horseshoes that had been stored due to the river water currents, my nox 600 continued to mark, there after a 40cm well appeared this beautiful cob dated 1610, the oldest cobs dated and documented is It is located in the museum of the National Bank of Mexico and it is a cob from 1607. So without a doubt it was a great find for me, greetings and thanks for creating this wonderful technology!
