I've owned my AT Pro for over 2 years now and without a doubt, it is my go to detector! For me the simplicity cannot be beat. That is what makes this detector so great. Yes just like any other detector you buy there is a learning curve but the AT Pro is not difficult to learn. I suppose the only down side is the lack of volume control if you are not using headphones. So if you do buy headphones to use with the AT Pro, make sure they have a volume control! Plus the AT Pro does not have a back light either but to be honest, that does not bother me at all. I rarely detect in the dark. If I did, I would use my LED headlamp.
Bottom line, you cannot beat the AT Pro for the price and ease of use.
