Got My new AT Pro Wednesday from Big Boys Hobbies (smokin` deal) put it together and hit the front yard....very pleased to say the least. 16 coins and a token in a couple of hours. Next day 9 more coins....took a break on Friday. Saturday went to an old school yard and found a few more pennies....one of them a wheatie. Today I hit the yard again and found several more coins. Total after 4 short hunts 37 clad coins, 1 token, 1 small crescent wrench, 1 cutting device, 2 pieces of copper wire, and a small square piece that I think is copper and has something to do with connecting copper wire. This machine is a coin hound! I have dug some pennies and dimes at 10-12 inches and I learned real quick that if you dig, find nothing, and it says it`s there...keep digging...you will find it. I have yet to dig a hole and come up empty handed. The bottle tops sound right on the iron audio, but some aluminum cans and small food cans (Vienna sausage/sardine) that are void of iron sound off as dime targets in pro mode. Sometimes the only indicator that it is junk is that the depth indicator will jump around from 2-10+ due to the shape of the object, but with a good signal. I don`t mind digging` a few of those as long as I`m finding good targets. Guess it just goes along with the territory.
