Marauder-2. Delta Pulse. Troubleshooting.

[tissaweera]

Is there a good discriminator for Marauder.

[kt315]

yes, DP3s. you have to pay for programmed microchip, to buy LCD and PCB.

good luck bro

[tissaweera]

What is the price of it.
Details please .
Thanks .

[kt315]

ask here http://www.geotech1.com/forums/showt...-Delta-Pulse-3
i do not have a relation to turkish projects.

[tissaweera]

It is not compatible with Marauder isn't it ?

[kt315]

i do not follow for all turkish projects. initially DP is deeper and for seeking big object on big depth.
so concerning phisical principes a big object gives same response either that gold or ferrous.
you see - here is NOT VLF DISCRIMINATION. why you wait disc from deeper detector?
thats nonsence.

[tissaweera]

Sorry for my lack of knowledge .

I am still a learner .

Thanks

did especial video to show How To Check The Sound. a resistor from +bat on wire is 1k.

unRAR. you have to do same way if you want more depth - the box, the batt, the transistor, the capacitors. it is a PI with 1000us pulse width of Eric,
he found otocha gold with. in that (THAT) case you can split power supply - 24V on MOS-FET, 12V on the rest of schematic.

Dear KT315,

Would it be possible to resend Eric's PI detector file (1000us) used to locate Atocha?

Thank you for your attention.

[kt315]

good question, but my name is not Eric Foster. my name is kt315. you mean AQUAPULSE TOWED METAL DETECTOR
no data on it. sometimes i use some tweaks because have unsold batch of boards, but what to do if people are indefferent sometimes.
they ask to sell board in winter time but all year they are sleeping away smoking cigarretts and waste money on american wiskey preffering.
then i do a reference on Atocha Gold because just Gold makes the people to move faster. Gold Gold Gold and their eyes shine brighter amigo.

pleasure

Thank you very much K315 !!

Your answers are always very good and true.

Perhaps Mr. Eric Foster can technically enrich us with his knowledge and creations.

Thank you all.

Hello KT315
I bought your Delta Pulse PCB. Here the photos

I want to know when i make 1 meter square coil How are coil thickness [ awg or swg ] coil turns, coil inductance and DC coil resistance
thank you Mr.

[kt315]

hi Asanka. good news you got the board. 500uH is optimal, while 380uH too (MICRO HENRY).
i did 16 winds, but i think this is much. do 12-13. ok, you have to take 12x4 48 meters
plus some reserve on ends, 3 meters.
to my sorry we do not still have full data on DP coils as they were in original (german) DP used.
awg swg are american standart and unknown for me.
2-2.5 mm diameter, 'on-copper', a multistrand wire in fat isolation is good, this is ordinary standart wire in any electric shop
you may get.
coil resistance will be 'as-is'.

MAIN RULE. you do not turn the detector with 1x1 m coil in your house because
that has no sense. all tests in a room must be just with small coil/coils.
1x1 m coil has to be tested outside your house, better place in a field with clear ground from metal garbage.

Thank you Mr. KT315 for your quick reply
I made old delta pulse, clone pi w, chance , polonish pi and felezjoo pi with small and large coil. but deep not enough for me.I made felezjoo 7 machines for my friends. But it deep only for air. not good depth and discrimination in the real ground. Therefore i test your delta pulse legend PCB.Please tell me Mr.KT315 these are jumpers in your board [ i marked it as a red round ]
thank you Mr.

sorry, do not see red in your photo
