2 boxxxx :)

Thanks kt315 and tartarlar.
Very interesting.

Yes its There, BUT AS IT SAYS in the Article:

"I DON'T RECOMMEND ANYONE BUILD IT".

There seem to be "TOO MANY PROBLEMS WITH IT".

Hey Gary,

Guess I should have pointed that out.

Do you think you will be developing this any further? I realize you had/have some health problems, but I was just wondering. I'd like to make a 2 box my next project.

Thanks,


joe

Health Problems are Fixed now.

I have been thinking about designing a considerably Different, 2-box design, but presently I have Too many other projects to finish up.

Maybe during this winter.

Diamond Detector

This 2box also works on the principle of electrostatic transmission which is already inside the ionic models. So aside from regular metal detecting it can detect metals which are long time buried from a distance greater than any other 2 box in the market. There's an auto trigger mode which allows the user to go in the direction of the target by looking the activity of the vu meter, before any sound will be output.
If you're interested I suggest you contact Mineoro and ask them to send you the manual. There you will read the wroking principle and the story of Mr. Anisio Trelha who in 1969 found several gold coins which triggered the auto mode from 120 meters away.
My buddy in my team has the MP10.

I know of a 2box manufacturer which was delighted by the Mineoro 2 boxes and recognized their superiority over his models. I never tried to detect gemstones becuase there ain't any in my area. So I can't speak whether it's also effective to that or not.
Now it's up to the buyer to test it.
My 2 cents.

Is it true that there is a machine like this the diamond detector that detects Diamonds, does anyone have circuit that detects diamonds from more or less 3 feet distance...any schematic and test results would be appreciated.

Any Perfect TR Locator

Any Perfect TR Locator is there, with ferrite rod type of transmitter and ferrite rod reciever, i have gone thru all this 2box posts and couldnt find any clear description of test results, some say these 2box are faulty and work only in air , ferrite rods should be used at Tx and Rx coils as an industry head making these told me, he doesnt sell to ordinary cirizens
Just post schemtics immediately as there are many huge treasure chests here located more than 10 feet in ground.

may be detect a roof sheet at 12 feet.................

To Geo and kt315, thank you for your replies.
to Geo: CW is continuous wave ( γεια σου Γιώργο , εδώ Pytheas )
to kt315 : I know about the “standart” two box design. I had the TF900 but it seems these detectors (TF900, TM808,Gemini, Garrett…) are not good enough for treasure hunting in real conditions. The TF900 it will easily pick up a (25cm x 25cm ) iron sheet in 60cm inside the ground (tested) , but olso it will easily pick up “ ground signals”. The 90 degrees Tx-Rx placement it seems perfect only on air tests. Also do not believe that those reports from companies ,about depth capabilities, is truth.
Some other tests on ground (metal mode) :
A) iron sheet (30cm x 15cm) in 120cm depth : not detected
B) iron sheet (35cm x 37cm) in 155cm depth : not detected
C) two aluminium engine cylinder head’s, say (43cm x 30cm x 15cm) in 170 cm depth (top) : not detected

If these fail easily then MAX also fails easily....even TxRx are not upto mark...

Ferrite based TxRx

If these fail easily then MAX also fails easily....even TxRx are not upto mark...

MAX will be using dual core latest Intel CPU assembled on mars as some one here said to detect using TxRx...many seems to be hard working on this site constructing but fail on groud tests.. nobody here has done correct ground tests with TxRx machines, any one has ferrite type of TxRx they show good results....and the transistors used have a Vceo of 40V at Tx coil side and these are not to be used....

the transistor Vceo should be considered in any 2box transmitter, as many say the tx coil gets about 120-160 volts, as far as 2 box designs are considered in the projects 2box pages and also construction page, is the Vceo breakdown correctly chosen in the already posted schematics...do these 2 box go 10 feet in ground, do these tests not altering the exixting designs with out any result.....

[sonar]

Change base resistors from 1,2K to 100 Ohm for 90 - 110V

TR receiver is total junk. 'Scrap' it and make own new one based on something like LT low noise op-amps. Some additional band filter there and line rectifier is very usefull too. Everything must to be mounted on the perfect construction.

Nice one Esteban. Its look like Gemini clone mounted on plastic pipe
