I see there are a lot of new owners of the AT series. I wanted to make sure this thread was read again, before finding this Forum & leaning on the knowledge & experience of these users my finds were mainly clad coins. Now that I have been detecting for a year now, I have found over 20 pieces of gold, a good portion of that with the Pro.
But one of the hardest things to do is to tell others to dig the nickel signals. On some mornings I dig 30-40 nickels looking for the finds I want, I call it low-balling.
This is important because the AT series is also very sensitive to coins. The noob I have been detecting with goes out 3 or 4 days a week now & gets $5-$9 in clad every time. I told him the hardest thing to do is to dig pull-tab signals, it's especially hard when you find that much clad. My point dig the Mid-Tone signals! the gold will follow.
But if you're mainly a coin-shooter thats okay the Pro is also a killer on coins.
