The Bandido II µMAX, which because of the micro symbol .. µ .. I also like to just say it as the [size=small]micro[/size]MAX as you did in the subject heading. 'Thank You' for that.
I compare them as being close in performance, giving the Eldorado micro-housed models the nod for having the ED-180 Discrimination to adjust for All Metal Acceptance in the Disc. mode for when tomes are favorable to hunt that way.
However, I general hunt in very dense iron littered sites and have taken advantage of Tesoro's excellent performance with silent search Disc. mode providing a quick-response and fast-recovery with the ED-120 Disc. circuitry adjusted for the minimum setting. The Bandido II [size=small]micro[/size]MAX will generally work a bit quieter than the Eldorado in dense iron when the Eldorado's Disc. is increased to be close to that of the Bandido unit.
I generally work my Tesoro's in dense iron when Relic Hunting or for quick work in tot lots and similar urban Coin Hunting applications. I think you have the right models in hand. I'm thinning down a few of the duplicate models in my arsenal but making sure I have a Bandido II µMAX still on-hand.
