Vallon VMH3CS Mine Detector

Someone sell Vallon backpack?

[tifred]

hello
I finished my changes.
I have to sell parts here.

I tested him ( Vallon VMN3CS ) briefly , on average soil .On ,, mineral “ - no problem -passed the procedure ,,ground reject ‘’.But in mode ,, normal’’ reacts very strongly to the soil . Of this mode gives signs , that he will register a pot with coins at 60 centimeters deep in the ground . On the mineral mode has no response on of the same pot . The test was with 15 x30 cm original , standart coil . Aluminum pan- diameter about 30 cm - reaction of about 50 cm in the air . Is there any new software that would allow ground rejection procedure on ,, normal ‘’ ? And allow registration of the above-mentioned pot ?

Love it. Thanks a lot !

Something like this.

BTW, what is the link to the firmware upgrade on the download page http://www.vallon.us/download/download.html

I can only see EVA2000 software (?)

Can anyone explain how to link a regular 9 pins DB9 RS232 plug to the six pins plug on the vallon ?

FRom : ... to...

Best regards,

Anyone can confirm this ? I remember to have read posts stating that the dongle was compulsory.

lytle78 is correct. No dongle is needed. Contact VALLON in Germany for update information.

Free Vallon firmware update ? Where do I sign ?

I am trying to clarify the ins and outs of firmware update. Based on reading the posts here and some information from a forum member, it looks like the previously provided pinouts for the Vallon connector - data in, data out, and ground can go to a standard Serial connector. As far as the connector - here are surplus ones for $7.99

The dongle is not needed and supposedly Vallon will supply the software free.

Great read and indeed very sobering

[lytle78]

Doing more background on the Vallons, I came across this. Sobering reading. Makes me think of those green things differently - like where all the red dust in them came from.

Well, finally got out in the desert - very preliminary results on a US 5 cent “nickel” on both machines were about 13-14” when buried in moderately mineralized coarse sand/small gravel. This is at preset settings. About what I could get with a TDI.

Well in my experience of trying the Vallon in Western Australia, I can say that it would have no trouble detecting gold from about 0.3g and up, at pretty fair depths. The biggest issue I found in my 12 or so months of trying the machine was the sensitivity to hot rocks. In fairly benign ground it wasnt an issue, but once I moved toward more difficult ground littered with a varied assortment of ironstones etc, it was "hot rock hell" You could ground balance to these, but then that upset the ground balance generally. In some places I tried it, I was literally digging up a hot rock every few feet! A DD coil would be excellent, but not sure that is possible.

From my experience. I was not able to balance out soviet balun nickel ferrite. Ground goes up to 10 led and detector still detects ferrite. No problem with magnesium soft ferrite. I also noticed that GB at 7, 8 led is about maximum that Vallon can handle without problems. I have no problems with pegmatite, magnetite, mediaeval brick floor.

I would really like to see a further development of this discussion - proven solutions for lighter and more “micro gold” oriented coil/mechanical solution.

I am very interest to read the results of compare with other detectors as TDI and ATX.

[lytle78]

Well, they have both arrived. On is a real “war veteran” showing signs of field use and the usual “broken ear”. the other one is nearly like new with only a couple of snags on the control decal to show it was ever opened. They both power up and check out, but I have to get out in the desert because our very “tight” retirement community is EMI hell.

Looking forward to compare it to the TDI’s I had and see how the depth on previously set targets is. I would really like to see a further development of this discussion - proven solutions for lighter and more “micro gold” oriented coil/mechanical solution.
