Can pinpointer detecting thin chain?

[Waikiki_Sweep]

That is an excellent idea.
Why I do not come up with that idea.

I made your idea but it dont working yet . look the picture.
I still know why.

The only thing that happened at turn on that my hairs went stand upright.

I bet you have a party all night before assembling that circuit. Try one more time when ready.

Beautiful avatar, you have.
Is that your new water dog, what's his name?

It is sea turtle. I almost broke my coil several times hitting them at night when they crossing my way invisible in water.
Do not worry, my coil is so thin and light and they have very good armor.

Hi, Nezocas

C1-C2 = 630V C3 = 400V C5 -C6 = 16V

Resistors 1/4 watt.

success

Any Capacitors Rated at 16 Volts or Greater Should work OK.

thank´s

Obtainig missing components
When finished, will post results

Can you tell us:

Capacitor voltage and resistor wattage

I think so.
Try it out!
Let us know the result.

thank you in advance

Also I have an idea how to make it compact.
As I already have told frequently with bigger diameter core that pinpointer will go deeper - MORE LONG RANGE.

So I think it is reasonable to get a ferrite ring or cup big enough to put SMD PCB inside and wind coils outside.
So you will have a perfect slim disk working as sensor for pinpointer. Pot it in epoxy. All indications and power supply put on other side of three wire cable.

Now you can attach that sensor disk to your metal detector coil (with some spacing), or scoop, or boot and hook indication block on your belt or headphones.
So there is no needs anymore to hold pinpointer in hand (or use tail )

That is an excellent idea.

.... Nupi you are a great inventor! ...

You're the smartest and nicest man in this forum.
I think we should hold a referendum and make you as chief administrator.

I have the schematic ready.
But I can not find it.

I am just interesting, Nupi you are a great inventor! Can you make that schematic automatically adjusted so there will be no needs in pots at all. If no adjustments are needed it will help to waterproof pinpointer easily and it will be simpler for use too. And may be it will self correcting for different grounds. What you think?

Hi,

Will this pinpointer work underwater....SALT water
I will give it a go in a waterproof case, inside a slipper to beach hunt

And in xx months time we going to see this solution in a patent registered by a well known company.

May I guess............? It starts with the letter M............

I do not know how to use pinpointer if I stay in water 4ft. deep all the day.
....
Wait a moment!!! Idea!!!
I can fill it with epoxy and put pinpointer inside my diving boot.
So I can find a target with my foot!
That is an improvement.

May be your LONG RANGE pinpointer as attachment for the boot is an interesting idea.
Imagine: If you have a doubts where target is just try it with your foot!!!
Anyway both your hands are busy to hold scoop and detector and you have no tail to hold pinpointer.

Thank you! Frankly I think your invention is much more valuable for that guys who hitting dust trying to find small gold nuggets.

But epoxy is too heavy.
I have a new invention.!!
Very special!!!!!! Months worked on!!!!!!!!!!
1 for $ 2 and 10 for 25 dollars
Special Rebate for you.
