Just got a brand new white's TRX pinpointer yesterday and got one hour to use it today..........Ok here is my review on the TRX pinpointer after a one hour hunt. I went to an old park and chose a small area and dug every signal. Most everything was 3-4 inches and 90% of the items I could pinpoint from the top of the ground so I was able to dig a tiny flap to retrieve the item. This pinpointer is powerful and very sensitive. Majority of the items were low tones and u can see from the pic it's mostly can slaw and pull tabs. I removed a piece of can slaw 2 inches deep and then rescanned the hole and got a nickel signal directly below it 4" deeper. That was the 1936 buffalo, also got a 1939 Jefferson and a button with an anchor. I give the TRX two thumbs up! For power and sensitivity!
