I just got mine last Friday. I make progress every day, it seems. My biggest hurdle has been accepting the fact that I will be able to hear what a coin sounds like when I have the disc set just above iron. The sounds are overwhelming at first! It takes a bit of faith and determination before Experience kicks in and gives confidence.
The best thing to happen to me happened this morning before work: I was out in my yard attempting to Power-Balance the Vaq. I got it set where I think I needed it and started sweeping the front yard with the disc set on Nickel. I hit what seemed to be a nice tone. It wasn't the blare of a surface penny, just a nice distant, solid signal. I dug it and flipped a "token" out of the hole, except I saw the words "quarter-dollar" through the dirt. OMG. She's a Barber quarter, 1906!!
I've got her carefully washed in distilled water and in a 2 by 2, but I'm still high from the experience! My house was built in the 50s, but my neighbor's house dates to 1908... so it makes sense that this baby was there.
After that, I immediately set the disc to Iron and started, not sweeping, but "scrubbing" the ground with the search coil! I really felt "in tune" with the unit, it just took some kind of "proof" that there are prizes down there, 5, 6, 7, 8, 9 inches. I immediately turned into a "dig it all" type guy. It just take the memory of that deep coin sound to light the fire....
