I just bought one. I haven't fully tested it yet, but as I expected, there are already some very tall tales about it, just as there are and have been about all other detectors, especially high end Whites and Minelabs. If it walks like a duck, it probably is a duck...
It is top-heavy, meaning that it tips over easily, but it is well-designed otherise, save for the coil mounting screw being right in the way of the coax cable where it mounts. It has a lot of volume, and expect 9.5" inches on an average coin in air (just like it says in its manual). American (nickels) do slightly better at around 10" with the 8" search coil, and 1/2-1" more with the 11"..
Mine with the 8" concentric coil tested 9.5" on a clad dime, 10" on a clad nickel. A Fisher Gold Bug Pro gets 10" in air on the same dime using a 5" DD coil compared to the EP at 9.5" with its 8" concentric coil. Personally, I would like a 5" DD for mine if it would work, and since it likely would, I'll buy one ASAP!
Add another 1/2" to 1" (in air) with the 11" DD, but don't expect more.
THIS DETECTOR GETS BETTER DEPTH IF YOU SWING IT FASTER! You could lose 4-5" if you pass over a target too slowly..
Yes, I know there are a couple of people out there making videos complaining about other people "whipping" coins in front of the search coil, but that's because they are inexperienced and unknowledgeable about how different metal detectors work. Don't pay any attention to them, they are merely voicing their "opinions", nothing more. Metal detectors are not all alike, their circuitries are all different, so each one has to be treated differently than another one.
This unit requires number memorization for best target ID, but it does seem to prefer items larger than coins. Items about the size of a large cell phone come in at about 15-18" in air. As the name indicates, it seems to be designed more for a European market and could easily double as a CW detector for relic hunting, but of course, a T2 would easily outdo its performance just as it outdoes all other detecors hunting CW relics.
Our best indicator of in-ground coin depth is an air test - because there is no other way to pre-determine that - save for using "Fe sample bars", etc. So expect 3" less in air than a T2, and 1 1/2" less in the ground for same size/type coils.
Note: It DOES NOT get 2" more in ground depth than an Alfa 2000, nor 4" less than a t2, even though the whopper stories continue otherwise. It is very sensitive to interference due to its hypersensitivity, and if you try to change modes indoors around EMF and other interference, or near metal, it may not work very well ..
I'll do some more experiments/examinations in 2 or 3 days.
