True All Metal No Motion Mode

Recommended Posts

Can you guys help me to compile a list of all current VLF detectors on the market that will run in a true ALL METAL no/non motion setting as a user defined base mode, not a hold trigger or pinpoint button held type option but a base mode of operation. Much like what the original M Scope Fisher Gold Bug 19 khz unit operated as.

I am seeking a VLF unit with least amount of or no discrimination that operates in all metal no motion, ability to turn up gain and sens as well as GB preferred and has ability to add large format aftermarket coil.

I believe that the Tesoro Outlaw has all metal no motion mode.

Thanks Mark,will take a better look at the F75, the term STATIC confused me at first, but this I see is just another way of saying it has a Non Motion all metal mode. Does boost mode variations make a difference while running in Static All Metal? Also is the 15 inch DD coil through Fisher for this unit worthy or better to add a large format NEL or Detech?

Is the Technetics T2 same platform as Fisher F75?

Reading the manual for the Fisher Gold Bug and Gold Bug Pro it says:

The All Metal Mode is more sensitive than the Discrimination Mode, and is used to find all types of metal objects in the ground. The searchcoil must be in motion for objects to be detected.

From what I understand the only Non Motion Static mode is attained but holding the Pinpoint button

Pinpoint is a mode of detection which does not require the searchcoil to be in motion. A motionless searchcoil held over a metal object will induce a hum; volume and pitch of the hum increase with target strength.

 

I am looking for options that run in a true all metal static or non motion full time mode with VCO, most units do not seem to have a dedicated Non Motion / Static All Metal mode because of difficulty for user with drift of signal. Most incorporate a type of pinpoint trigger or button to temp switch into mode.

Oops, I did not zero in on the "non-motion" part and so deleted my other post.

The T2 and F75 are similar but are different detectors.

As from learned elsewhere in forums there is a difference in true Non Motion All Metal and All Metal running through DISC set to zero.

 

The Original Gold Bug 19 khz had no DISC and ran in a dedicated No Motion mode with VCO 

 

Some of the detectors are fuzzy as to how the All Metal mode is truly filtered as a stand alone mode or through DISC set to zero. am I correct on this Steve?

 

From what I understand true ALL METAL is always static or Non Motion, but few current platforms run a dedicated mode for this as it is not user friendly with drift problems. Most channel through a filtered Disc mode.

Here is an old discussion from another board on the SST that gets into the subject

http://www.dankowskidetectors.com/discussions/read.php?2,44115,44514

 

I see you chimed in on subject Steve.

 

What I dont understand is other posters commented  "There's no way for a machine to give variable audio tones in True all metal NON motion" 

This statement confuses me because my experience with the original Gold Bug run in No Motion mode it certainly had great VCO tones

All metal can be had in both motion and non-motion modes. Non-motion is pure and unfiltered and therefore is subject to drift. Very few detectors offer this mode.

Motion all metal modes add a filter, commonly referred to as SAT (Self Adjusting Threshold) or Autotune. This attempts to keep the threshold steady and if the coil is held motionless over the target the threshold fades away. Motion is required to keep the target beeping so we have "motion all metal". The higher the SAT setting, the more aggressive the filtering, the less depth. Nearly all VLF type nugget detectors employ this mode.

We can now add a discrimination filter. Items pass through the filter and are accepted or rejected. This filter requires more signal strength to deliver a result which is seen as lost depth.

Many low cost detectors only operate in discriminate mode. They can achieve a fake "all metal" mode by simply accepting all targets. However, the filter is still being applied and depth still lost.

VCO is not discrimination per se. A normal detector simply increases the volume with target strength. VCO increases volume and pitch. A loud squeal simply means a strong target. 

Notes on filtering

Picture: Garrett Ace 250 features an "All Metal" mode that is a discriminate mode set to accept all targets.

As always Steve, thank you for your very easy to understand summations of subjects, I can glean information across all boards but get easily confused as everyone uses like terms but dont always apply them in correct context.

I bought and tested 5 different platforms recently and moved on from all but the TDI SL PI unit. Am still looking to upgrade the VLF original Gold Bug platform with a detector that operates in the mode as described above.

The next units I plan on trying are the Tesoro Outlaw, Nokta Impact, and now going to look at the F75 (with boost and DST?) From reading the manuals I know that both the Impact and Outlaw have a dedicated true Non Motion All Metal mode unfiltered channel, and the Outlaw actually has a retune button to deal with drift just as the M Scope Gold Bug did. I believe the Detech Chaser 4.8 khz model may also have capability but is not available in US yet and havent found the manual for this model.

      While experimenting with my Gold Racer, I think I saw more stable VIDs by raising the coil and scanning perpendicular to magnetic north. There seemed to be a height that was most stable, and scanning perpendicular to magnetic north tended to eliminate oscillation between very low and very high values.  It wasn't perfect, but it was suggestive.  I'm wondering if anyone else has anything to offer about this.

      Hope this video helps someone with their next detector purchase..

      I wonder if Minelab will build a dedicated nugget detector in the style of the equinox, but with gpz type technology. This seems to be the way the CZX by Fisher is headed. I think the Equinox will open up many more machines in the same style eventually. I would hope for concentric and dd coils and more power in a lightweight dedicated nugget hunting package.

      A nice summary quote from Tom Dankowski about why Simultaneous Multi Frequency (SMF) is worth consideration over single frequency options...
      “SMF's punch through bad dirt better. Hold on to accurate ID's at depth....and in bad dirt....better. Handle EMI better. Genuinely handle wet-salt better..... to include more accurate ID at depth.,.,.,.,.,.,.,., and a host of other rationale/justifications.”

      First Texas (Bounty Hunter, Fisher, Teknetics) - last new models Fisher F75+ and Teknetics T2+. Next up a new pulse induction (PI) beach detector. A new digital multifrequency to replace the Fisher CZ3D is long overdue but at this rate we will be lucky to just see the PI before the end of the year.

      Garrett - last new model the AT Max. Hard to believe the flagship GTI 2500 has been around since 1999 with no updates. Garrett so far has shown no interest in multifrequency. The most I was hoping for was a lightweight dry land version of the ATX, but so far no sign of that happening either. I doubt we will see anything else from Garrett this year but they could surprise.
      Makro - last new models the Multi Kruzer and Gold Kruzer. Makro has mastered single frequency so everyone would like to see what they can do with multifrequency or pulse induction. I expect Makro is done with new models for the year.
      Minelab - last new models Equinox 600 and 800. I have no idea what’s up next for detectors but I sure would like to see that small coil for my GPZ 7000. I really don’t expect anything new for the rest of the year besides Equinox accessories.
      Nokta - sister company to Makro. Last new detector the Nokta Impact. Up next the Nokta Anfibio.
      Tesoro - Who? What?
      White’s - last new models the MX7 and TDI SL Special Edition plus the just announced Goldmaster 24K. Hopefully that new tech will eventually see the light. Right now just getting the 24K out the door is job one.
      XP - last new products the HF coils for the Deus, with X35 coils and XP Orx due by end of year.

      When I saw a video showing the Makro Gold Racer recovery speed using two nails and a gold ring, it caused me to reflect on the various internet nail tests. Nearly all employ modern round nails, when these items rarely present issues.
      The common VDI (visual discrimination scale) puts ferrous items at the low end of the scale, and items with progressively increasing conductivity higher on the scale. The problem is the size of items also matters. Small gold is low on the scale, and the larger the gold, the higher it reads on the scale. A silver quarter reads higher than a silver dime, etc.
      All manner of ferrous trash including medium and smaller nails fall where they should when using discrimination and are easily tuned out. The problem is large iron and steel items, and ferrous but non-magnetic materials like stainless steel. Steel plates, large bolts, broken large square nails, axe heads, hammer heads, broken pry bar and pick tips, etc. all tend to read as high conductive targets. Usually it is just the sheer size pushing it higher up the scale.
      Detectors also love things with holes, which makes for a perfect target by enabling and enhancing near perfect eddy currents, making items appear larger than they really are. Steel washers and nuts are a big problem in this regard, often reading as non-ferrous targets.
      Oddball shapes cause problems, particularly in flat sheet steel. Old rusted cans often separate into irregular shaped flat pieces, and roofing tin (plated steel) and other sheet steel items are my number one nemesis around old camp sites. Bottle caps present a similar issue in modern areas. These items produce complex "sparky" eddy currents with both ferrous and non-ferrous indications. Many thin flat steel items produce remarkably good gold nugget type signals in old camp areas.
      Two general tips. Concentric coils often handle ferrous trash better than DD coils. A DD coil is often the culprit when dealing with bottle caps where a concentric coil often makes them easy to identify. Another thing is to use full tones. Many ferrous items are producing both ferrous and non-ferrous tones. Blocking ferrous tones allows only the non-ferrous tone to be heard, giving a clear "dig me" signal. This was the real bane of single tone machines with a simple disc knob to eliminate ferrous objects. You still heard the non-ferrous portion of the signal. Multi tones allows you to hear the dual ferrous/non-ferrous reports from these troublesome items, helping eliminate most of them.
      Certain detectors can also show multiple target responses on screen at once, like the White's models featuring the SignaGraph (XLT, DFX, etc.) and CTX with target trace. These displays show target "smearing" that stands out differently from the clean VDI responses produced by most good items. A machine with a simple VDI numeric readout can only show you one number at a time and the only indication you might get is "dancing" numbers that refuse to lock on. Usually though the predominate response overrides and fakes you out. This is where a good high end visual display capable of putting all VDI response on screen simultaneously can really help out.
      I have been collecting these odd iron and steel items to practice with and to help me evaluate which machines might do best in ferrous trash. The main thing I wanted to note here is contrived internet videos with common round nails often present a misleading picture. Many machines do very well on nails yet fail miserably on flat steel.
