Hi All, I took the ET Pro out today with the 5" DD coil attached. Same area I have taken it to before when I made my prior posts. I wasn't sure what to expect...I reduced the sensitivity to 6, but ran the disc on zero. Hunted for about 2 and a quarter hours....found 43 coins, 30 of them were our ( Aussie) 1c and 2c coins. 8 of them were our pre-decimal coins, 4 copper and 4 silver, including a florin at over 4". I found that with the small coil I was able to identify non-iron and isolate the better finds more quickly. None of the coins were super deep, but all gave good signals on the Eurotek. The combination with the small DD coil is terrific. Certainly the one to use in really trashy ground. HH, Pete.
