T2 ?

What advantage of the iron disc range on the T2 vs F75
I run my F75 disc from 0 - 6 most of the time when EMI allows

PS Tom thanks for a worn out 1926 merc dime from a small
field 75 x 150 ft that gives up few coins these days.
With my CZ70 8in coil just for practice under power lines
Toms video and the way he attacts a target .
Well 2 nails in the hole later it was merc time Thanks Mike

T-2 has high resolution iron discrimination. Iron VDI range is 0 -40. Whereas the F-75 is 0 - 15.
BUT, 0 - 15 is more than ample for nearly every application; especially since the F75 is a much deeper unit.
