Despite a fairly steep learning curve and a confusing screen interface, it very accurately detects objects in soil with pinpoint precision. Pro mode is going to be deeper than standard mode but you will need to get used to the crackle that it makes. For instance, with the ACE 250 I needed VDI/TargetID, more accurate discrimination, ground balance and an 11-inch DD coil.

The advanced Proportional (Pro) audio modes enable the user to hear subtle changes in a target’s response, helping them judge a target’s size, shape, and depth.There’s a steep learning curve going with an advanced metal detector like the at pro which could ruin your fun outdoors.

Our family loved metal detectors, worked and trained for over 15 years in America, at the major construction company Garrett. From what I have read since they ironed out the issues with the first release a few years ago 99% seem to be very impressed. In the photo above, you can visually see the normal division of low, mid and high tones on the AT Pro detector.At first, we kept pinging almost constantly, but there was no way metal was so prevalent in the area.
