Wasted money on this worthless piece of junk.
by Ron Roesch in Philippines - 
It gave beautiful pictures of false readings. Could not even detect a tunnel 3 feet under ground. A 2 twig dousing rod could give a better reading. Do not waist your money on this like I did. And do not believe them if they tell you they will take it back and sell it for you, they will not. It was a big disappointment for me and a lot of wasted time.

Treasure Hunting in 3d
by R. D. Torres in Mexico - 
I have the eXp 4000 gold package. It has the 3d ground scanning feature, the visual detector system for discriminating the metals and the so called supersensor. When I scan the ground with the supersensor I get better results that with the standard GPR probe and can obtain a higher depth performance. I specially use it to find precious metals mostly small targets like coins, jewelry or rings. But also I'm looking for large underground tunnels and caverns. This detecting instrument has been usefull for me and offered reliable results. To look at the 3d images is very fascinating and interesting. It shows the underground and included targets from former times that noone would have noticed without this tool.

Great Depth Performance
by Tom in PH - 
Last year I bought the eXp 4000 to search for buried treasure and caches. I noticed that the depth performance to search for metallic objects is better than any other metal detector. I found metal boxes in about 8m depth which could not be detected by other detectors I have. Even if the unit is little expensive, the tool is much usefull for me.

It Is Not Worth It!

Unusable device at all, at least for me.
