Delta Pulse

[nick_f]

Hi Nick,

Thats the way a test should be presented(Post #799), Thanks for sharing.

The diode is for isolating the Fet's capacitance from the coil therefore increasing the resonate frequency of the coil = faster

Regards Mark

Hi Mark,

You're welcome and you're right about the diode role in circuit.
In the previous messages the diode was considered unnecessary and I wanted to get to a consensus, wether the diode can improve the results.

Regards,
Nicolae

delta

hi all
my name is iman. i iranian.


ibuilt delta pulse ,but it is so so. i mean it detect a metal at first time but when i movethe coil back over that metal its not work ( detect )

un stable.

please help me.
How much in depth can detect with search coil 1*1 ???

my email : i.belief @yahoo.com

Best wishes

Regards too all!

in this test DP detect at 2,20-2,40 a small tank.This man is 1,90 tol.

Hi spyros. What about the coil. I think it is 1.25x1.25 !!!!

Dont know...something is very funny here!? Pretty strange and unique response on such distance?? Pretty fast response!? I have been tested many high end PI detectors so far, but never saw something simillar - such fast and sharp response at simillar distances. Lorenz DeepMax, Pulse Star etc..etc... those also can detect simillar object at that distance...maybe a bit more than that. But their response is much slower and wider.
At this particular video it is all so suspectable! Looks like some smaller coil is attached on detector and hidden to right side where md operater stands. Operater is observing movements of other guy and with one hand closing some other smaller object to smaller coil, so we hear such response. This video looks like huge FRAUD to me! I have seen it for 20 times and analyzed each second. Maybe i am wrong...but for me this video is FRAUD!

On the other hand, this video is NOT FRAUD;

Delta Pulse, for example, is acting exactly this way. So this video is right and presenting real thing.

Of course this video is not FRAUD.
But at the other video i see that the signal is very strong. So why they did not put some stones yet down the coil, so to detect the object at more distance????
A Simple question.......

Maybe, but I am not sure, my friend. Look at his full jeans pockets. Even there are only cigarettes wrapped in foil, the test is in question. And what about the shoes with different metal parts?

And metalic watch on her hand? Man should walk in bathing suit, provided that it does not have gold teeth or screws in the bones. Better yet to carry out such test by pretty girl with without all clothes or piercing.

No, i dont think it is relevant - small metalic items in pockets. Delta Pulse with such large coil is very inert on small items. Very very inert. Although.... your way of looking does make some sence...
But what is presented on that video is not miracle, neither something extra rare to achieve with DP. DP can perform even much better. So i am beleiving that video is OK, not a joke or a fraud.

The day that Rospy made the test (near my city), he called me to go for the test, but i was very busy with the farm and i did not hear the phone. So I am sure that the video is not Fraud.
Also as Ivica said, cigarettes foil, or coins etc don't excite this big coil. Look careful, it begin to beep before the person (Kyriakos) walk in the coil

Delta pulse

Hello everyone

Delta Pulse works very well, can detect a soda can of 333 ml. At more than 1.40 mtrs. With coil 1X1 m. in the air.
Sorry do not speak English.

hi..seem u know a good deal so give a help man....

[quote=Alexis;29526]Hello manu,i will tell u a real satuation..i am 46 have some understanding for tech...i try to breif...in the lebanon we have a lot of greek roman sites.so in 1994 1995 i made a hit.this was with cscope metadec 3 and two box garret and only after someone tswap the earth by a cat.he save me 1 ,2 ,3 meters .so around 50 cm were left over targets...i made a 48cm coil pi scope and found another target at 72 cm football size at1995.so i think that i still have 4 to 5 targets there.i took all easy ones they have large reflection surface some 60cm in dia.i am thinking to buy a cheap locator and make a big coil .or i can buy a hand held erm for 170 $ ? advice me please. thank u man....i tell u my story with this site is unbilevable..i left hight school in 1981 so excuse my dictation....
