Minelab Coil help

[ded]

I am using an xterra 50, I have the standard 9 inch round and 5X10 DD coil. In my soils the GB on the round is often about 2 and with the 5x10 its about 9, I think this is why the depth between the two is very close 5-6 inches for good target id in very dry conditions. (it goes deeper but tid becomes very iffy)

What do you think I could expect with the 10.5 DD round ?

I expect some extra depth (how much) and do you think the good target id depth will also improve ?

I have no idea but will be watching. I have the X70 with the extra coil and I have no idea what to expect either. Seems to be a shortage of ML users.
