Tesoro Brown Concentric

[Merc]

Is there any chance that Tesoro would use non-standard coils on the Compadre? The coils are permanently cabled to the control box. Internal trimmers would allow adjusting the ground balance and discrimination to match the coil. It would work but it would not be compatible with other coils. That would not matter of course because it is permanently connected to the control box it is shipped with.

I noticed one of these brown coils is one I have had since the early 90s and has "Monolithic Shielding" printed on the label. As best I can remember, that was an experiment of adding materials to the plastic to give some level of shielding. The newer brown concentric looks the same but does not have the wording on the label. The one that says "Monolithic Shielding" has quite a lot of phase shift when I place my hand near it. The white concentric coils give no phase shift no matter how I move my hand all over the coil. Did Tesoro give up on this shielding technique?

this is the only one i think of that has 'monolithic shielding':

but this brown one also says monolithic shielding:

who knows if the brown one really has monolithic shielding?

was the white one built for the laser scout detector?

the europe/uk version compadre has 8" polo coil
