Based on how the machine reacts after dissing up and over 50 in some areas... I have had to reduce sensitivity in some high EMI Areas after increase of discrimination.so it's kinda toss up in some places.

Where I have noticed the 50 up helps the most is in areas that have high interference and sens has to be set at 40 or below.. Still hits targets 6 to 8" after going to 50 and up. Plus you do not hit all the junk.

Just my take ............ Only an opinion.
 
Here is the reason why many users choose 50 as the disc on a T2. My bench testing done a few months ago. The dynamics apply to both the 5" & 11" coils.

Model - Teknetics T2/Software version 6.5 (from 6.0 onwards version numbers make no difference in depth according to First Texas Products)
Coin Used - U.S. Quarter - Cupronickel
Coil - 5" DD
Sensitivity - 60
Tone Selection - 4

Discrimination Levels

0 - 9" depth reading (extremely noisy due to EMI & machines internal circuitry noise)
10 - 7" depth reading (approx 50% less noise than 0 disc setting)
21 - 6 1/2" depth reading (quiet)
30 - 6" depth reading (quiet)
40 - 6" depth reading (quiet)
49 - 5 1/2" depth reading (quiet)
50 - 9" depth reading (this is where another huge increase in Gain occurs, besides the zero setting. Same noise level as 0 disc setting)
60 - 9" depth reading (approx 50% less noise than 50 disc setting)
70 - 8 1/2" depth reading (quiet)
80 - 8" depth reading (quiet)

Observation - the Gain does not seem to follow a straight linear output as disc is increased. Notice that from 0-49 disc there is a 3 1/2" range in detection depth. From 50-80 disc there is a 1" range.

0r

If you remove the disc 0-9 results from above, there is a 1 1/2" depth range between disc 10-49 and a 1" depth range between disc 50-80.

The large gain increase at 50 and the 10-49 disc range has serious implications on how a user sets the discrimination. Below are object disc ranges on T2:

OBJECT / TARGET I.D.

gum wrapper foil / 40-55 (majority of gold rings/jewelry with any detector are found within the foil range and below foil range)
U.S. Nickel / approx 58
alum pull tab / 60-75
alum screwcap / 70-80
U.S. zinc penny / approx 78
U.S. copper penny-clad U.S. dime / approx 83
U.S. clad quarter / 89
U.S. silver dollar / 94
 
That is good info Elton.
