Too few details... how to say you need this or that for detect stuff at 7 meters ?

What's exposed (to flux) area of target?
Which is composition of it ? Ferromagnetic or not ?
What about soil ? Mineralized ?
What about carring ability ? 1 person or more or a vehicle ?

You know... find a coin at 7 meters it's impossible... but if it's a T90...

even old jetco will see it...

Kind regards,
Max

Hi mmlove2007,

As Max say finding a coin at 7 meters it's impossible...
But with one good PI we can detect treasure in good depth...
Now we must say what PI is the best in more depth???

Deltapulse seems good but, please members say to us better option to select....

what is your opinion, max?
what is your idea mmlove2007?

Hi,
yes, but do you wanna really my opinion about ? ok... my idea is... other option to delta is hard to make it work: goldscanIV, is absolute champion at depth, between all PI schematics available and around.

But the project is truly hard, full of pitfalls....(now also much old) and are missing informations...e.g. pcb (though seems there's one from Vladimir ?)... tuning/calibration.

Already discussed in other threads...

If you make delta pulse, can make also xr-71 that's about same stuff, can make hammerhead, tuning them is far more easy than gsIV, but still I think GSIV is superior cause works on brute force at tx and refining at RX.

Drain lot of current , of course, but if you wanna depth...

Other PIs... I don't know you can make and gain such advantages in performances.

BTW I don't like PI much... are good toys at beach... and for depth search but for me most of the time useless.

Kind regards,
Max

toy for deep. bombers' finder.

delta pulse and xr-71 have ONE schematic, Max. do not mislead people. these are only names given by two Bulgarians. we know them as Gueorgui Gueorguiev and aban - first has done XR-71, second has done Delta Pulse.

quota:

About XR71 I can say that it "Father" XR7 (I had manifactured 3 devices before
XR71) was one very fine designed Pi machine. If you are interesting I can send
you shematics of XR7.
Best regards,
Gueorgui Gueorguiev

XR7is full diferent than XR71. It is other detector.
XR7 is clone of DBP-2010. Before 3 months i had one.

For me the max depth has the Superscan from Eric. The detector with original coil (1x1m) can detect a soda can at 1.8 m on ear.
The Best!!!!
If Eric read this thread, can tell me about the wire diameter of the coil of SuperScan???

E-mail me schematic of XR7 please on [email protected]
must to compare... there are differiencies or not... but please do not send DPB-2010 one vice XR7.

in wait of your goodness, welldoing and to have one's heart in the right place.

Hi KT315.
Sorry but i did not reversed the pcb. I attach here some photos of the pcb and the box. Photos was taken by Rospy

I forgot the front panel with the model

thank all friends

pleas uploded cicuit & full shematic or pcb 7 meter metal detector

Hi,
about delta and XR71:
they are about same stuff... I already wrote that, in my posts.

Just small differences. Schematic is maybe 95% the same.

So performances are about the same at same frequency.

In delta setup frequency is around 100Hz, in XR71 is around 400Hz, but, of course, changing some components values you have about same machine from them.

Was discussed many times already in these forums...

Kind regards,
Max

Hi,
is superscan schematic available ? Is the one in the thread here ?

1.8m on air for a can is a fair result. Really powerful.

Kind regards,
Max

Max, thanks for photos!

is there anything on Lorenz? I see their first LP5 is working on 1300/70 Hz http://www.lorenzmetaldetector.com/l...fications.html
is it sorta of Delta Pulse?
last Deep max X3 is working on 2100/1400Hz! http://www.lorenzmetaldetector.com/d...fications.html
