6000 DI PRO SL (XB) / XL PRO questions

[akille68]

Hello I'm a newbie and proud owner of the above detectors.

This is my first 3d, so hope that You'll be pleased to give me a chance with my questions.

DI PRO SL (XB): What XB means for?

COMMON QUESTION:

Setting GEB/DISC:
I've read this 3d http://www.findmall.com/read.php?56,521535 and Monte's GEB/DISC setting procedure:
"The Signal Balance is tied in with both the All Metal GEB mode as well as the GEB-Disc. motion Discriminate mode. Hunting in the GEB-Disc. mode, you want to set it as high as possible w/o any "noise" or chatter. The handy way to do that, after first adjusting the tuner for a slight audio threshold and ground balancing the unit, is to keep the coil on the ground, motionless, and increase the Signal Balance until the analog meter needle starts to fluctuate. Very slowly reduce the Sig. Bal. just to the point where the needle stays steady at the '0'. Don't reduce it too far, just to where it stabilizes."

This means that I must, first of all, (in GEB/NORM) setting threshold and ground balancing (air/ground), change mode in GEB/DISC and then play the trick with the GB to is max affordable range. What I don't understand is that manual said that after every changing with the GB knob I must redo auto-balancing...uhm a bit confused...

COILS:
Just got a DD 4x6 coil. I know that is not performing as the 6" ones, but here in Rome ground is high mineralized, so hope to have a better chance to discriminate; right or wrong?
Btw, I'll take 6" in the next future.

PRIMARY RESEARCHES : MILITARIA
I use these wonderful detectors on WWII battlefields, so I cannot appreciate their coins killer qualities. So, I would like a light discrimination, 'cause not all iron is bad in militaria (bajonets, helmets...). Can You give me some tips? Btw, some tests on different relic examples are going on.

DETECTOR STAND:
I need to know which detector stand fit correctly to these models, to keep control box out of wet grass and off abrasive ground.
Maybe P/N 502-0115-1 ?

I've bought a new 3900 D/PRO PLUS, produced by White's UK (still in production). I know that is an analog, no motion detector, but that's all. If someone knows something more about this model (largely used in Italy for militaria). It looks like a TR detector...'cause its settings are very similiar to that one for the 6000s in TR mode (alternative settings to balance in high mineralized grounds).

NEOPRENE PADS:
I need to replace the neoprene pads under the meter. Any idea where to get them? Maybe self-construction could be a solution?

That's all folks!!!!!!!

Many thanx for Your attention,

Best regards,

I don't know exactly how Monte tuned his but this is what I did, first I turned up the Signal balance at least to the preset position and went thru the ground balancing procedure. Then I would check in all metal to make sure there was no increase in signal as I moved the coil up and down. If that checked out ok, then I would increase the signal balance up and repeat the process. There would be a point where instability would start to be noticeable and where the ground balance would be off. What you don't want is there to be falsing going on in disc mode, that is where I would back the signal balance down some. Usually somewhere between 2 to 3 o'clock would be the ideal area for the signal balance control to be set for me but that would change according to interference and ground conditions in different areas. Maybe Monte can chime in and help with this but I think the above should give you a general idea.
Everytime you change the signal balance, you must reground balance, I think that is what the manual is referring to.

Hi Steve,
Thank YOu for reply,
I agree with You, so this is the reason why I don't understand the following Monte's procedure:

"... after first adjusting the tuner for a slight audio threshold and ground balancing the unit, is to keep the coil on the ground, motionless, and increase the Signal Balance until the analog meter needle starts to fluctuate. Very slowly reduce the Sig. Bal. just to the point where the needle stays steady at the '0'. Don't reduce it too far, just to where it stabilizes."

It looks like that he increases ground balance only after having ground balanced.

Only run enough signal balance to make the detectors signal balance stable for best performance no matter which coil your using. The procedure for best signal balance performance is in the owners manual under advanced operating procedures and if you adjust it like they say you will get max performance out of the XL Pro. If you run it to high or overdrive it for the ground conditions you may be hurting your maximum performance. The XL Pro is at max power from the factory and the signal balance does exactly that, balances the signal for maximum power, to high or to low and your performance will suffer. The signal balance control on the XL Pro is a little different than the gain or sensitivity on a regular detector even though it works in sort of the same way by running as much as the detector will take while remaining stable.

absolutely correct bill!..the "receive" coil is set at maximum power from the factory!..the transmitted "signal" is the one you 're balancing when adjusting the signal balance control!..this IS the reason the signal balance control is NOT considerd a "gain" control,because you are NOT adjusting for electronic gain,that is set at maximum power already!..the objective is maintain a "stable" correlation between the two,so as to obtain "maximum" sensitivity,power,AND STABILITY for the
ground conditions you are encountering at the site you are hunting.

Every time you change the signal balance you must verify that the detector is still balanced correctly by re ground balancing the detector. This will verify that you did not increase the signal balance to much. At the point were the signal balance is at its most max position while allowing the detector to still ground balance is were you will get the best performance. Go just past were the detector stays balanced with the signal balance, then back the signal balance down slowly, a bit at a time re ground balancing each time till the detector balances ok. This is the spot were the XL Pro will perform its best.

The Xl Pro is set at max power from the factory, by balancing the detectors signal balance to max ( while keeping proper ground balance) will give you all the detectors available power for the ground being hunted at the time.( this is key with the XL Pro set up )

Take Care,

Thank you j.t. and hello to you again. I am surprised how many guys misunderstand the signal balance function on the XL Pro or 6000 series detectors. I love my XL Pro and I am pretty sure you feel the same about yours, to bad Whites made the decision to stop producing them.

Take Care and H.H

right bill!..if you do not adjust it for the conditions encountered,then in essence ,you are "sacrficing" the detector's ability to hunt efficiently,and effectively!..as you stated,the signal balance control is "critical" to the pro's performance!..one of the best coin snipers ever built,and a ton of fun to use!..know your detector,and use it often,and don't worry about the latest ,and greatest,you already have the "edge" when you understand your detector,and have the experience gained in field useage!
