Anyone with a 2-box?

08MI

Since we are on this subject, let me add this.
I used to have one of Mineoro's 2 boxes , model 08MI. This was before I had the PDC. Unfortunately I had to sell it to make money to get the PDC and I also I did not needed it anymore... Now I had the PDC. Later on I bought the Minelab's excalibur for diving.

I must say that the O8MI is a superb unit, besides working on the same electrostatic concept Mineoro developed which make it unique, It can have a lateral reading of 120m(!) in the case of long time buried gold or silver.
In those cases it can reach about 20 m deep.
It's been in the market for more than 30 years. In 1969, Mr Anisiso Trelha with one of those could locate a cache of gold coins that were 120 m away. The vu meter showed activity, triggering the automatic mode and he followed the signal to the target.
I don't know of any 2 box which can do that.
I don't know however if it can beat another top brand 2 box in terms of locating deeper metal which is not long time buried. But as I said, having the electrostatic concept onboard is great.

Besides there's an optional acessory probe which allows the user send it in water, say river, etc. deep caves, etc..

My partner on my team has a MP10 also a superb unit.

Tried a Minelab SD2200 today... finally found the 2nd battery which, fortunately, was still charged, since I can't find its charger now. Anyway, failure again.

This has turned out to be a very interesting exercise.
I guess the next question that comes to mind is - at what depth can the 1Kg cache of coins be detected?
This would be a much more difficult one to answer. I suppose you would need to bury several similar caches at different depths. Could be expensive and time consuming .....

Yes this has been an interesting test. If an SD2000 can't detect a jar of silver coins at 24" with a 18" coil I guess nothing can. The SD2200 has detected smaller sized nuggets at this depth but of course we are talking one complete metal object not a mass of individual coins.

My guess is that if the jar was full of nickels(representing low conductor small gold coins) the SD2200 would detect it. After all my mini cache of 12 nickels was detectable at 20"(only 4 inches short) in air with an 11" coil (GS5). Even adjusting the pulse delay to 25us does not really give me a significant depth increase for small high conductors like small silver(Perhaps it would for larger sized solid objects?). It is hard to ignore the depth advantages low conductors have on PI machines when you consider that a low conductor nickel can be detected close to twice the depth as a high conductor silver dime on my PI. My guess is that a PI could only pass this test by using a mass of low conductor coins.

Perhaps Carl's Hammerhead with the 1m coil will be successful.
We must wait and see...

[Esteban]

Hmmmm, think this don't solve the problem. Big coil is for big targets at high depth.

Hmmmm, think this don't solve the problem. Big coil is for big targets at high depth.

With 1 m x 1 m coil it is possible. Maybe Ivconic with his PS2 with 2x2 m coil can make the test.

[ivconic]

yes....


Already tested simillar tests....PSII can not detect some items i beleived it can!? Very good on large items but on small-very undefined!?
I do beleive that some of Minelab's could do a job....
Anybody tried some of Troy Shadows ...?

Those long-haired metric *******s... probably a vegan too.

OK, so today I got my first cache down... 3 pounds (220 count) of US silver quarters. I hit sandrock at 30 inches and that was it for depth. Put the silver in a small plastic container, so the very top is right at 24 inches deep.

Tomorrow I will pull out a few detectors and see what happens.

Hello Carl.
I have done a test last weekend with my new Nexus Ultima detector. It is the only one so far which could get good stable signal in discrimination from a 1 kg of bronze-copper-silver coins at 24" depth under compact undisturbed soil.
The Nexus Ultima is with dual 20" loops search coil (875 x 500 x 25 mm)
I will have soon the test results on my web site www.nexusdetectors.com
Will be interesting to see if some of the machines you`v got can pick up signals on your test side.
All best.

Whites on the U.K. web site quote depths of 3.5 feet on a 3" square of metal,4.5 feet on a 6" and 4.5 feet on a gallon can for their two box. As Esteban mentions solid metal gives good depth while that of a hoard of coins is much reduced.
Has anyone tried testing say a coke can and a similar sized container of loose coins to see what the depth difference would be ?

The coke can goes much deeper than similar container full of coins.

hi all of you

hi
i dont know if what i'm saying is wright or no
firs of all talking in 4 feets and more and for big targets you have to talke
about large coils,
i made a device that can detect a matal objact 20cm2 about 3m under the ground, you all now will say how?
by increasing the curent in the coil it will be ok ,how, we are using the irf * 640 670 ets
i am using the biger one that can holdes 40A and i'm not using the 20awg its two small for that curent
(every thing in this life has a smaller one and a bigger one ) all of you are using the 20awg why? the smaller one ok we can build a biger device who sad that it will be 20awg
you have to say why, why you'r not using the 23 or 25 or smaller coil becouse they cant pass grate curent than the thiker one
and thats my perpose
so when the curent encreses, the megnatic fild is also geting biger you have to know that, and for small object it will work also becouse we have increased the laps or turns of the coil.
why we dont aske questions?
why are the large coils less sensitivity for small objects and small coils are good
becouse of the nummber of laps or turns becouse ech turn will generate a singel signal that means the 1\1m which consists of 11 laps will generate 11 signals and the small objects can be easyly pass through the signals
but when we use small coils we have lets say 50 laps so we have 50 signals ...
and ther is another thing which we will take in concederation whic is the how many signals should pass through the coin to make noise in he second coil or in the recive stage when we are using singel coil ?
think about it
and i'm sorry becouse of my langwage becouse i'm an arminian
