DEEPERS

[LDTVN]

There are no errors in the places you specify. Pay attention to the polarity of the power supply.

Hi all, the deepers 8 schematics work and it have good dept, I had make and used, the problem is calibrating process is little complicated if you don't know the deepers details, see the deepers 10DD posted by me its almost the same design, if somebody detect an error in deepers 8at please post details here.

thanks

HI MFC tell please deeper x8 IRF740 pin 1 is not correct and pin 2 its must be to r11 search coil

[MFC]

Hi sbalio1 the deepers version is deepers 8 at, not deepers x8, the scheme of deepers 8at work because I built two units and they work. I am working in deepers X5 and deepers 10 DD, now the version 10 is working and soon I will post pictures and scheme updates.

take care

[sbalio1]

Thanks MFC my regards. But is there enny defirence between deeper x8 and deeper x8At thanks to put a file here to deeper x8AT ahave no file for it

[MFC]

The deepers X8 dont exist, deepers are Deepers 8at and Deepers X5

Versions are
Deepers 7
Deepers 8at
Deepers 10DD
Deepers prospector
Deepers MF
Deepers 2x1
Deepers X5
Deepers MaxiDetect (last model)

I put schemes for 10 DD, 7 and X5.

Hey MFC. Haw grunt balance Deepers ? No grunt balance ili Yes ?

Bed zatvor curent 5mA = irf740 !

Is thus a depth of 70cm on a 1 Gr. Gold nugget reachable?

[pustareka]

Minlab SD2000 !

BED BED BED !! Depers no GRUNT BALANCE !!

PCB SD2000 Minlab ???

Pustareka, can you share LTspice asc file, to check what are the timing of detector

For me this detector has following disadvantages:
- no 2-nd sample to cancel magnetic field (as it is in SD2000)
- no 2-nd channel to cancel ground ministration (as it is in SD2000)
- fake discrimination ability.
Device can be used only on non-mineralized soils.

Yes, no cancel grunt. Bed mineral detector.

PCB SD2000 ?

Ok deepers don't have ground balance, but in Cuba exist a red ground in my town that I doubt fully that these minlab sd2000 detectors work. The extreme mineralization level is hard to pass, Most dept lost for any detector. Its a physics problem. The very high conductive terrain. Ok the deepers have not any ground balance but if the terrain permit prospecting it have very good dept, maybe more than 1.5 mts with the frame 1x1m very easy. For the deeper you most use less sensitivity using pot sensi, and after balance and adjust. You must familiarize with any detector if not you will never use efficiently. Other thing, deeper circuit is more easy to do.

Some times the use of a metal detector can depends of the features of the machine in fact, some good in some grounds and bad in others, nothing is perfect, the better macines can be too much expensive.
