One thing I love about my AT is how fast I can cover a modern area with it. Hit a crushed asphalt / dirt parking lot this morning for all of 1 1/4 hours with the 5x8 coil. Nothing deeper then 2" but flying! 41 coins, a .38 special case, a small nail up hanger (old one), and a base metal charm. Cherry picking at it's best! I love finding old stuff but a quick hunt like this is just flat fun.
