I have used the AT Pro for almost 2 years. It is a phenomenal coin machine. I own 7 high end machines including minelab ctx3030' Excalibur 1000, whites DFX, MXT, and gold bug II. Each machine has a specific purpose. The AT Pro is by far the best detector on the market for the money. Ihave over 100 rings and $1500.00 in coins to prove it. It is not a CTX but everyone does not need or can afford a CTX.
