I have had my AT Pro for about 4 months now and I find it very versatile and easy to use. I love it and don't see a need for anything else, given the types of hunting I engage in. I like to use the smaller double D coil. I like the waterproof features; I can use it in the rain and in streams around here without worry. It is very helpful in Pro mode with iron audio
once you get used to it. When I first started it up I had info and sound overload, and I wasn't sure it was working properly, but I just had to get used to it. Now that I've logged about 120 hours on this thing, I love it. I can tell what kind of coin is under it, and what kind of pulltab usually as well.

It finds all sorts of relics, picks stuff out of trashy environments well, and seems to really take a beating.
Ok, some cons, or what might be cons for certain users:
I will say, I've noticed that some folks have trouble hearing the tone roll audio when it's very subtle. My hubby is slightly hard of hearing and he cannot seem to hear the range of those low tones sometimes. I've heard people say they can't figure out how not to dig bottle caps with this machine and have wondered if they had similar issues and didn't even know it. Sometimes it is a very subtle change.
Also, I will note that I am only 5 feet tall. My hubby also hates the headphones that came with the AT Pro as they don't work as well for someone 6 foot tall or over. The cord is too short and he gets hung up. The other complaint many have is that the optional waterproof headphones are uncomfortable and don't have a volume control. I see now that there are a pair of amphibious headphones with volume control made especially for the AT Pro by a popular manufacturer of detector headphones, but they are pricey. Finally, I prefer the smaller Double D coil as the machine to me is heavy and not balanced well with the stock coil. If you are used to a well balanced detector, you may not like the nose heavy feel. I think I find a lot with the smaller coil, but sometimes I wonder if I sacrifice any depth or other functionality. But the stock coil starts to make my arm hurt.
That being said, I would still buy this detector again in a heartbeat and it was worth every penny to me!
