I am referring to the single 9 volt Tesoros with the small control housing (the [size=small]micro[/size]MAX housing).
Some of the models with be a factory preset Ground Balance operation and some with both a true All Metal mode and the external Threshold adjustment will offer manual GB control.
Also, some with have a selectable All Metal search mode and others will only have a momentary All Metal Pinpoint function. Not all models with a selectable All Metal mode have an external Threshold adjustment.

I know the Golden has it and Bandido.
I take it you mean the Golden [size=small]micro[/size]MAX [size=small]
(µMAX[/size]) but you didn't clarify which 'Golden' model. Also, there were four 'Bandido' series models and you didn't qualify which one.

The Silver has the toggle but no threshold knob.
If you mean the 'Silver [size=small]micro[/size]MAX', it, like the forerunner Cutlass II µMAX, have a toggle that is labeled "All Metal" but that isn't a true, Threshold-based All Metal search mode. It is just motion-based Discriminate mode selection that is supposed to be at or close to All Metal accept or Zero Disc. This is the same as adjusting the Compadre or new Mojave to their minimum ED-180 Disc. setting which should be at, or close to, Zero Tejection for All Metal acceptance in the silent-search Disc. mode.
This may not be a complete listing of all the 9-Volt powered Tesoro models with a selectable true All Metal mode with a Threshold-level adjustment, but it ought to answer your question, or at least I hope so:
Models with a toggle-selected All Metal / Disc. control but no external Threshold control:
Sidewinder
Sidewinder [size=small]micro[/size]MAX
Models with a toggle-selected All Metal / Disc. control but an internally adjusted Threshold trimmer, that had an external manual GB control:
Bandido [size=small]micro[/size]MAX
Models with a momentary [size=small](pushbutton)[/size] All Metal Pinpoint function, and externally adjusted Threshold control, but an internal GB trimmer:
Silver Sabre [size=small]micro[/size]MAX
Cibola
Models with a toggle-selected All Metal / Disc. control, an externally adjusted Threshold control, but an internal GB trimmer:
Conquistador
Conquistador [size=small]micro[/size]MAX
Golden µMAX and 2nd version Golden µMAX
Models with a click-selectable [size=small](Disc. knob)[/size] All Metal / Disc. control, an externally adjusted Threshold control, and external manually GB control:
Vaquero
Models with a toggle-selected All Metal / Disc. control, an externally adjusted Threshold control, and external manually GB control:
Bandido II µMAX
Eldorado [size=small]
(last version in microMAX housing)[/size]
Euro Sabre
Outlaw
As I stated, I might have missed some but this gives you a general idea.
Personally, my preference is to have more operator control and that means a selectable, Threshold-based All Metal mode and manual Ground balance. Of the above list, my personal favorites in order of preference are:
The Bandido II µMAX, the Vaquero, then the Eldorado.
Of those that have an internal GB trimmer, with a choice of toggle selected All Metal or just an All Metal Pinpoint feature, my preferences, in order, are:
The Silver Sabre µMAX, the Conquistador µMAX and the Cibola.
