GB control range on my Bandido ll uMax .

Hi !

Regarding the effective range of the Ground Balance control on the Tesoro Bandido ll uMax metal detector, the manual states on page 9 "The entire effective area of the control is 3-3/4 turns from minimum to maximum", i.e. from start of "drag" point going in the CCW direction to start of "drag" point at the other end of the range going in the CW direction.

My Bandido ll uMax has a GB control range of only 3-1/2. Does that indicate my GB control needs adjustment or replacement ?

Thanks in advance for your help :please: .

Thanks ! I'll be PM'ing you soon.

Todd :)
 
Randy,

After I sent you a short PM saying that I would be PM'ing you soon, I sent a full-page PM.

Problem is, I can't find any record of it on my end of this forum.

A copy of it should be in my SENT mail, but it's not !

If you didn't receive, it must have gotten lost in cyberland somewhere.....Yikes !

Please advise.

Thanks,
Todd

I did'nt get the pocket cards in my PM, you can go by the manual and compare ground balance procedure to your pocket cards. Maybe the pocket cards had too many bites to transfer to a PM, heck I ain't no computer whiz, and I barely fit into todays standard of computer knowledge. But.......I do know how to G/B a Tesoro. Tell you what, just PM me the procedures that you are having trouble with and we can go from there. I ought to start a new thread on how to G/B a Tesoro, but it would not apply to the newer Vaquero, Tejon or Cortes, because they are newer than my newest Tesoro, The 'ol Bandido ll

I agree, check your PM:thumbup:
 
Once you get it balanced dead on turn the knob a hair to the right and you will give it a more positive ground balance which works best for most units in most minerlizations...Matter of fact most units with a set ground balance are set slightly positive....

Hey thanks Dan ! I believe Monte V. Berry stated the same thing in a post here a while back ! I keep forgetting to set-up for a slightly positive GB, but will try to remember the next time out........if the ground ever dries up ! We had a lot of rain in March, 2011 and I hate digging in sloppy mud ! :thumbdown:

I appreciate the reminder !

Todd :)
 
Hey Dan, Y'all may want to shoot me for stirring,but after hunting with my Tejon for years now and setting up the GB a hair positive (and doing very well), I come up on some forum where this someone is reccomending to set the GB a hair Negative because most all factory sets are already a hair Positive, thus any added to the positive side amounts to it being too much to the positive side. He said this with a reasonable enough confidence in what his results had been not to disbelieve what he was saying, SO,??? , bout time we think we got it all figured out along comes someone to mess with our cornflakes and stirr things up. Beats me, but I will say that I had noticed for myself one day that I was digging some pretty deep stuff and when I checked my GB it had become a bit Neg. ?? Well, as usual when all is said and done we have to backup and do what we know from experience, "Experiment" and experience what happens when GB is set a hair Pos. Different machines we know have their own minute ways of being different, so what may work one way for some may not work for others, in different locals/dirt etc. Likely there will be little or no difference in the effect, then maybe too, a big difference, and most of us want very much the" mostest" out of what we got, so tinker with your machine until you know which is best for your situation.All this brings to my mind the advice and reasoning to continuely check your GB. It may even fluxuate back and forth from Pos to Neg, with first one way,being better, then the other being better,.All depending on the dirt ?? LOL,sorry to have messed with y'all's cornflakes boys but it had to be done. Any input and clarification on this subject (if possible) now is much needed and greatly appreciated. HH, Charlie
 
You're right Charles, setting the ground balance the same can give different results in different ground conditions. Most, if not all, manufacturers suggest a slightly positive ground balance setting, but that's not always the optimum setting. Here in north MS there is virtually no mineralization, but there are a lot of small hot rocks that will give positive signals unless the ground balance is set more positive than recommended. Also, on some detectors the disc mode will be balanced too negative when the all metal mode is set to a "correct" ground balance. Some of the Tesoros I've used, including the Golden
 
Thanks for reminding me as should always add in my neck of the woods to my posts...Heck dial in in expertise of the operator, mineralization, swing speed, and most of all the tuning of the unit in hand from the factory as your buddy hunting with you with a Tejon may have different results because of any of the above or a few aspects I missed. Heck messing with cornflakes makes one think and above all experiment as always a new trick or two to learn.Hopefully we will get some more input as we can never know enough....In addendum proper ground balance is a must as
set improperly it can hurt more than help....
 
Hope I am NOT opening a can of worms here, it is NOT my intent.

I have a question and a comment.

There has always been uncertainty about the Bandido uMAX GB system Some say it ONLY balances the All Metal mode, some say it does both.

I have found that if you want the best GB while detecting in the DISC mode is to GB IN the disc mode.

The reason we have been taught to GB positive in the ALL METAL mode is so that the when switching from All Metal to the Disc mode we will not detect the ground influence as we lift the coil or set it down while digging. IF we GB for example a Pantera or a Toltec II in the all metal mode, the disc mode will be more positive than actually needed, this prevents the ground noise. (I am referring to units made say 5 yrs ago, and I will say for my example, Tesoro only) . IF we GB the above mentioned units in the Disc mode, the all metal mode will then be slightly on the negative side.

So, if you tect in Disc mode, you should attempt to accomplish the GB in that mode IF your unit allows for this. Same for IF you detect in the All Metal mode.

In closing I will say, a tiny bit of improper GB in either direction isnt going to impact anyone much at all.

Well Gents

That is why I told Todd to G/B to a neutral setting, with no threshold change as he lowers the coil to the ground. He told me in a PM that that he hunted mainly in auto-tuned all metal mode the most, and you need a steady threshold audio to work in this mode. Since he made my personal PM to him come up in a the open Tesoro forum, well I guess you guys can handle his questions for him. Good Luck All of you guys.;)

Randy,

Doesnt the bandido have a self adjusting threshold to keep things steady?
