Nokta Impact DI3 Mode 001

Hi everyone, here is a short test with the Nokta Impact. I am very new to this machine and cant make heads or tails of the settings yet, but I thought everyone would like to see some good and odd things using the DI3 mode that I detected with today. I wont say if its positive or negative as that wouldn't be fair to the machine since today was my first real day using it in the field; but you can share my confusion :D ....Enjoy
MANUAL INSTRUCTIONS. Impact DI3 Mode: this is the 3-tone discrimination mode deigned for coin hunting especially in trashy sites such as parks. In this mode, the device produces a low tone for ferrous targets with 0-15 ID's a medium tone for gold and non-ferrous metals with ID's 16-66 and a high tone for non ferrous metals with ID's 67-99 such as SILVER brass and copper. By using the tone break feature, you can adjust the break points of the target response tones on the Target ID range.
