......but would like a little more control so i can tweak things.
Your statement answered your own question.
But let me start from the beginning.
The MXT, as we all know is a very good detector and i had one. I switched later to the M6 because of the tone ID.
After two weeks with the F75 i sold my M6 because the F75 can do more than the MXT or M6.
The biggest mistake Whites made with the MXT was to give it the 9.5 concentric coil as standard. That coil sees too much ground and too many targets at once. Most of the time you have to run it low on sensitivity because of the coil. You can overcome that problems with the 10x6 DD coil.
The MXT does not have as many tone ID modes as the F75. If you count the 2 tone relic mode as a tone id mode it has one. The F75 has 8.
The processing modes of the F75 gives more control of the (preamp)gain than the MXT with the three modes (coin and jewelry, relic, prospecting).
The batterie life of the F75 with just 4 AAs equals the life of the MXT with 8 AAs.
The F75 has less weight.
The F75 IDs targets better at depth.
The DD coil of the F75 separates better than the 9.5 standard coil of the MXT.
The DD coil of the F75 is deeper in bad ground.
To overcome ground chatter on the F75 just adjust the ground balance a little to the positive side.
The F75 has a backlight, the MXT has not.
The F75 has a static all metal mode, not on MXT.
You can bent the armrest of the F75 to fit your arm, not on MXT (maybe one time, hehehe.
I don't know if I covered it all, but yes, I think the F75 is the better detector.
