Recently bought a new Tesoro Silver u max and really like it. However, I have read many forums where people rant and rave about Tesoro's great discrimination. Why will the discrimination not knock out aluminum pull tabs. They sound just like coins. Is my detector faulty? I'm very disappointed after doing all this research to buy Tesoro now I'm not so sure!

First off, you do have a great detector. You need to do some air testing and find the point at which it will knock out a pull tab. If this does not agree with what your disc dial indicates, loosen the set screw and set the knob so that it does. On mine, pull tabs are knocked out just shy of zinc penny. This setting on mine will get all the pull tabs. No bear in mind that does not mean the detector will be silent when it hits some. You will hear pops and clicks as they may be partially discriminated. No big deal, just slow down the swing and pick the coins right out of the trash.
One more thing, when you have the pulltabs discriminated out, make sure you can still get a zinc penny.
By rereading your post, I don't believe you have your detector set up right. When you say it will not knock out tabs, where is your disc. set at?

Quite possibly you need educate yourself by viewing charts that show what range of discrimination certain items fall into. To the best of my knowledge, most VFL detectors react the same. EG: old can lids show as 1/2 dollars on VDI's, gold & pull tabs share the same range, etc. Some show probability a little better than others BUT, it is still probability. Understanding your machine should be your first priority.
If you are new to metal detecting, don't expect treasures to pop out of the ground. I had the Silver. The only reason I do not have it now is due to the extremely hot ground we have here.

Funny tester day out at a park I turned up discriminate to max and would read pull tabs loud and clear. Today I did an air test and knocked out pull tabs right to the left of pull tabs and still read zinc penny's. Hmmm. Don't know . Been detecting since 1990 and owe two Garrett detectors.

My Outlaw would do that with tabs and some bent nails while the targets were still in the ground, but my Silver doesnt have that issue. I have a beaver tab pulltab buried in my test garden at 4 inches that rings up like a silver quarter with the Outlaw but the Silver will chop the signal quite a bit. My Xterra 705 thinks its a copper penny so its not just Tesoros that have this issue. I wonder if there is an internal adjustment that can be made?....

I've never had problems discriminating out pulltabs with the Tesoro's I own. I do know that they can discriminate out a little higher or lower depending on the different shapes and size. Old rusted bent nails can sometimes fool you and sound good especially when your digging "iffy" type signals. Seems to me as long as you have all your settings like ground balance etc. set correctly, no bad emi and nothing in the hole with the tab reading higher you should be able to cancel it out?
