Recently I made some tests on the Garrett Treasure Ace 100:
This is not a deep seeker, but the discrimination is very good. I also found that it was good in trashy or iron infested areas. It has an 8" Crossfire coil that can locate small nonferrous targets easily.
Here's some results of an air test:
All tests were made with the discriminator control set to reject a large iron nail. This corresponded to the 5 cent setting on the dial. Depth measurements were determined by a consistent signal, and were recorded to the nearest 0.5" (rounded down).
1878 Victorian penny = 7.5"
1978 British 1p = 6"
1992 British 10p = 5.5"
1983 British £1 = 6.5"
1987 Singapore 20 cents = 5"
1997 Singapore 50 cents = 6"
Pull tab = 6.5"
1977 2 Deutsche Marks 6.5"
1957 1 Deutsche Mark = 5.5"
1979 U.S. Liberty Dollar = 7"
2000 U.S. Liberty Dollar = 7"
1998 U.S. dime = 5.5"
2002 Australian 5 cents = 4"
2003 Euro 1 cent = 4"
2003 Euro 2 cent = 4.5"
1999 Euro 5 cent = 5.5"
1999 Euro 10 cent 6"
1999 Euro 20 cent = 6.5"
2000 Euro 50 cent = 6.5"
1797 George III copper coin = 8"
circa 1425 Henry iV hammered silver = 4.5"
1888 Silver threepenny bit = 5"
1898 Silver sixpence = 6"
1865 Silver shilling = 6.5"
1899 Farthing = 5.5"
17mm diam Roman coin = 4.5"
22mm diam Roman coin = 5.5"
32mm diam Roman coin = 8"
3.5" x 5.5" OXO tin lid = 15"
Coca Cola tin = 13"
In "All Metal Mode" there was an increase in depth of between 0.5" and 1" depending on the target type and size. In some cases (such as the U.S. dollars) there was no change.
See photos below:
Note that there is a small potentiometer on the PCB (top left - second photo). The original setting is in the middle. This was tested in various positions, and it was found that only the sensitivity appears to be affected, but not the discrimination.
