Monte,

In your first paragraph above, you are of course speaking of the settings you ALWAYS use on a Bandido II MicroMAX in the Discriminate mode.... That is correct. . In the Discriminate mode I always leave the Disc. level at the absolute minimum setting.


I also stated I set the Threshold for a proper level which is a slight audio 'hum' or 'Threshold-audio.' That's done in All Metal or Pinpoint. I also stated that I set the Sensitivity as high as possible. I run it at maximum and reduce it only as needed for stability and no more. That is a function only in the motion-based Discriminate mode that uses the variable Sensitivity. The All Metal mode is non-adjustable and fixed for a Full Sensitivity level.


ToddB64:
For hunting Gold and Silver jewelry in the All Metal mode, how would you set up the Bandido II MicroMAX controls?... The same as I would above, but if I intentionally want to search in a Threshold-based All Metal mode, then I would adjust the GB to be as close to 'spot-on' as possible.


ToddB64:
I ask this question because I like to hunt in AM mode (for a little more depth and initial target information) until I hear a good jewelry-sounding target and then I switch into Disc. mode ...... The All Metal mode can generally provide a little better depth as long as it is tuned so you can hear subtle target responses based upon any ground noise or ground irregularities you hear during the sweep. Then, switching to the Discriminate mode can give you a little added info based on how loud to soft the target's response is to help 'suggest' a possible target 'size' or coil-to-target 'depth.'


ToddB64:
... and thumb the Disc. dial on up the arc to see where the signal breaks off if in fact it does, and how the signal characteristics sound breaking off and coming in again as I thumb the dial back down the arc. This process gives me an indication of whether the target is (a) worth digging or (b) most likely trash.... And here is where we differ in search technique. I used to find a lot of gold jewelry when I lived I and hunted larger metro areas, and gold jewelry can range in a very broad-range of conductivity level. Tiny gold ear ring studs, dinky gold baby's rings or small, thin bracelets.

From baby-size jewelry to young women's and adult-size gold and silver jewelry it can still be very thin rings or thin and small pendants, wrist or ankle chains, often thin, to the medium and thicker-size gold neck chains, especially some of the heavy and thick wrist and neck chains worn by some men. The thicker and wider-size women's rings to typically larger-size men's rings and we can easily span a conductivity range from small, thin foil level to that of a Copper Cent or even higher.

In short, ANY metal target that produces ANY positive, up-scale audio response should be a "target worth digging" that very well could be a desirable piece of jewelry. The best way to put the odds in our favor is by site selection to pick the places most likely to have lost jewelry. Beaches, around wading pools and sunbathing areas, tot-lots & playgrounds, sports fields, etc., etc.

I ALWAYS leave the Disc. at the minimum setting to allow me to hear the best audio target response, then I can quickly Pinpoint the target, recover it, sweep the spot to double-check and make sure there are no other targets, then get back to searching for more. Never, and I mean NEVER, do I spend any time tinkering with the variable Disc. control, and for a few very good reasons:

1.. When 'thumbing' the Disc. control while sweeping the search coil, you are not going to get a proper or clean and clear audio response compared to adjusting , stopping, and then sweeping the coil. If adjusting while sweeping the coil you are feeding in both ground and target information, and during the sweep that can have an effect on the signal received, processed and audio quality.

2.. Jewelry is most often found closer to the surface and not real deep making it quicker to be recovered. Also, jewelry comes in all sorts of sizes and shapes and can be oriented in many different positions when lost, from laying 'flat' to 'on-end' or 'canted' in off positions and that can have a big effect of the quality of the audio response, or visual with those models, that we receive. It makes it especially difficult to get a good lock-on visual TID and that applies to the audio information we are going to hear, too.

3.. Time spent sweeping and re-sweeping and re-sweeping as we tinker with the Disc. control can simply be a waste of time. It is also altering the audio response from a better good signal to one that might be broken-up and on to being rejected and, in the end, that tells us nothing. All we get is a lot of different audio information that WE are changing and not the located target, and it is simply an assortment of audio responses while time is being wasted.

It is much quicker to get a 'hit' and pinpoint the target, quickly, then make a recovery and have the target, good-or-bad, in our hand. Audio responses over and over and over tell us very little. A visual response is going to tell us everything, so just use the 'Beep-DIG!' technique and know, because ....

Monte......If you don't mind, I would appreciate answers to my questions regarding your comments I colored brown and I also included the paragraph numbers of your above reply for reference.

Re paragraph #1: In your first paragraph, you are of course speaking of the settings you ALWAYS use on a Bandido II MicroMAX in the Discriminate mode.... That is correct... In the Discriminate mode I always leave the Disc. level at the absolute minimum setting.

The Tesoro Compadre has Extended Discrimination 180, also, when the dial knob is turned to the far-left of the arc, just before clicking OFF, the faceplate says it is set in ALL METAL . OK, that's clear enough. However, the Tesoro Bandido II µMAX has ED120, also, it has a toggle switch for ALL METAL at the center position.

Now, my questions are: If the B2µMAX's DISC LEVEL dial is set to "MIN" , (a) is the detector actually operating in ALL METAL and If so, (b) does that dial position cause the machine to operate the same as it would when the toggle switch is set in the ALL METAL MODE center position and (c) if not, which setting would give the most productive "circuit-operation" for gold and silver jewelry hunting, i.e. ALL MEAL MODE or DISC LEVEL MIN ??? Maybe some tough, but IMHO important questions to be answered.

Paragraph #3: ToddB64:
For hunting Gold and Silver jewelry in the All Metal mode, how would you set up the Bandido II MicroMAX controls?... The same as I would above, but if I intentionally want to search in a Threshold-based All Metal mode, then I would adjust the GB to be as close to 'spot-on' as possible.

I think I know the answer to this, but when the toggle switch of the B2µMAX is in the ALL METAL MODE center position, is that when it's in the "Threshold-based" All Metal mode ?

Paragraph #8: I ALWAYS leave the Disc. at the minimum setting to allow me to hear the best audio target response, then I can quickly Pinpoint the target, recover it, sweep the spot to double-check and make sure there are no other targets, then get back to searching for more. Never, and I mean NEVER, do I spend any time tinkering with the variable Disc. control, and for a few very good
reasons:

With reference to your statement colored brown in the above Paragraph #8, am I correct in assuming that's because at the MIN setting of the silent search DISC LEVEL, you hear the best audio target response not clouded over or masked by ground mineral noise ?

Paragraph #9: 1.. When 'thumbing' the Disc. control while sweeping the search coil, you are not going to get a proper or clean and clear audio response compared to adjusting , stopping, and then sweeping the coil. If adjusting while sweeping the coil you are feeding in both ground and target information, and during the sweep that can have an effect on the signal received, processed and audio quality.

With reference to your statement colored brown in the above Paragraph #9, just to confirm, are you saying that when operating the B2µMAX in DISC LEVEL mode, that even though the machine is in silent search, meaning there is no Threshold "hum", there is still ground mineral noise mixed-in with any target signals, and both of these sounds are being electronically fed to the detectorists ears ?

In conclusion, thanks for your advice on "adjusting , stopping, and then sweeping the coil", as apposed to and the pitfalls of thumbing the dial after getting a hit to see where the signal fades out and then deciding whether to dig or not.

Best Regards,
ToddB64

I understand. The CleanSweep kind of limits depth on its own.

Monte 46 December 13, 2019 06:53AM

Clean Sweep depth decrease but area of detection greatly increased.
