two box metal detector discrimination

[kt315]

have i to reminder your words for you now??? do you NOT BELIEVE your hands your eyes and your mind???

I do test for cash around 200 ml liter of coins in plastic container but I not that the device can see this at 50 cm but in different reaction

i say you again VORTEX EDDY CURRENT IS NOT OHM CURRENT
we say about eddy nature of the current and just about it

[sheekh]

HI kt ,
I am not saying ohm current will formed I am saying eddy current ,
any way I have been met Eddy before long time ,but till now you didn't meet the current "situation"
it seem when we get older we start lose experience because of drifting .
yesterday i decide to make another test I change the phase 180 degree then the device start detecting this cash normally.
your comments highly appreciated regarding this
I am sure you know this before ,
but I am not getting any scientific answer .
regards
Sheekh

As Carl said, you really need to use motion detection to achieve good discrimination. Although it is possible with non-motion, it would be tricky to implement and may not be that successful. There are valid reasons why motion detectors completely replaced TR non-motion many years ago

Clear many thanks my friend

two box metal detector no need for discrimination only you need is ground balance
two box docent recognize small object like pulse induction i mean nails or even iron rod

and anyone think wto box is bad look at this machine

it is powerful

disc mode in two box is called CAVE. yes, for cavity seeking you understand right. cave and disc is same phase shift.
in later TM-808's whites refused from this mode because - you understand right, like me - low depth in this mode.

look the panel

is this really working

on 0:30 interraption of video. he does test 7UP in ALL METALL.

Operation in the CAVE mode will produce a positive sound for all non-ferrous metals such as gold or silver, and will produce the same response from voids, such as a cave. When a ferrous target, such as iron, is encountered, the sound will respond by going quiet. The same is true if there is heavy iron mineralisation.Since the ground balance is not affected in the CAVE mode, leave the GROUND BALANCE control at the NORMAL range. Because the ground mineralisation is not cancelled, the CAVE mode does not achieve the depth that can be expected in the METAL mode.

I found this in the SC9000 MANUAL which is the same look like in tm800 , my question is this really working
many thanks

Full iron rejection by Tm808 success
Thank for all great people in this fourm

[kt315]

with iron rejection you lose seriously the depth. do not exult.
