15*15 sheet of copper in 2m depth !! possible??

[landman]

I'm working on something. It's a chart of all the major deep detectors. And how far they claim it goes on a given size targets. It's
going to take some days but I'll publish it here when I'm done.

dear landman
these informations are really useful . I suggest that make 2 rows for depth in ground and are .
thanks for your works .

[payam20]

yes u are right they are expensive and heavy but i dont know how much it make difference in real situation ( i have calculate : it will increase the depth by 10 %)
i will make coil and post the resualts . i am working on another shape of coil ( i think it make a antastic resualt )

Here's my chart of deep detector stats.

@ payam20

look at google for: silver plated alu wire
http://www.amazon.co.uk/Silver-Plate.../dp/B008HFK6QS

Seems its for necklaces or whatever, but seen from the electric attributes, it would be perfect for md coils !!!



@ landman

Thx for the depth stats but I'm sorry, those won't help you much further.

The 1st png is pulse induction without useful metal discrimination and the 2nd -
Golden King vs. DeepHunter is false, because the Nokta values are not practicable!

Already in 2009 the Jeohunter and the Golden King have had almost the same depth values -
the Jeohunter was a bit deeper - it is built more stable and with better coil, even better PCB.
Because the creators of the Jeohunter did concentrate their whole work on metal detection and
not creating some milk-giving-wool-chicken with all kind of additional gimmicks, bells and whistles.

Meanwhile the DeepHunter for shure is minimum 5-10% deeper as the Golden King because
the creators of those detectors are brothers and they have their own special competition running.
But what counts much more are the great additional - usage and handling - improvements
of the DeepHunter and that it also works with high sensitive and lighweight motion-coils.

btw. The following also is an interesting table -

especially for comparing with the attached one.

What is DBP2010? is it the same as XR71 and Delta Pulse? which PI is good and can penetrate deeper?

DBP2010 was before Sniffer XR-7. XR-7 is same like DPB2010. after XR-7 was born XR-71, that is Delta Pulse (a copy clone of some German detector). DP is good.

A horizontally positioned coil combined with a vertically one - this can't work well ...

And if somebody hold this thing infront of his belly its completly uncomfortable,
otherwise its only possible to search a small track either to the left or to the right.

With a sweeping 50cm coil someone gets much better results, especially because
such a coil doesn't misses all the other interesting objects, even if someone can still ignore them.

hi dear kt13

ty for your video
have u made it your self ? I am really intrested in tow box they are perfect and most of them have good depth in ground . and u can easilly make your changes 2 it and make it what u want . i have mad 2 box sasho it was well but i want to enhance it . (it could find a 15*15 shhet of copper in 140 cm but i think by som changes it can detect it in 2 m ) and i have test it in ground 2 and resualts was perfect its depth is 90% of the depth in air .

i will be glad 2 work on it with u .

@ payman20

Such detectors are only for the comfortable ones or to discriminate all stuff smaller than 15cm
but don't expect too much depth if someone holds the coils already 50cm above the floor!

You will never ever find a 15x15cm plate at 2m with it, not even in air.
if its buried you may find it at 50cm maximum with such detectors, but only if you walk directly over it.

Look at the guy and how stupid he holds it - he will detect the metal of his belt, this detector
detects its own electronic box in the middle and it seems that even the poles are made of metal.
Forget it!

dear fun finder the box and the loops should be sheild . and you can adjust the hight of metal detector easily the detector loop can be adjuted to be 30cm above the ground and the other loop must be adjusted this metal detector can find a car in 12m easilly ( in the ground )
i will work on sasho in 1 month and i will put the info right here
but how much would you pay for a meltal detector that could find 5*5 in 120cm and 15*15 in 180cm and a car in 10m (OFCOURSE IN GROND MEANS BURIED IN GROUND WITH HIGH STABILITY )???

hi payam
my friend can detect 45cm tray by 120*120cm coil in 3.50merter(not my test) in air.do it by DP2.
so you make 2box and send it for me. it is work if i want make it?
