Correct the connections?

¿Dónde está su escudo Espaciado Gap?

Hello.
Yes. Placed on my reel

Hi @Virdi_248,

Where is your Shield Spacing Gap?

5mm to 10mm Gap (Shield must have OPEN Gap)

It's there.. Just covered by tape.

hi, Dfbowers
I think you have the opposite RX input.
RX START input is not inverted (pin 5 lf 353)
END RX inverting input (pin 6 lf 353)
if dual-tone sound, then turn 180 º RX
greetings

You are correct. Problem is solved by flipping over coil.

wire connection of the arrow?

It is just that, that is my question.

Hi @Virdi_248,

... At the end leave 5mm to 1cm gap. This is OBLIGATORY! Without gap you get NO Faraday shield. Worth nothing! ...

Look at colors.. does this help at all? Bare GROUND wire in cable goes to same connection as GREEN wire on PCB.

Does this help you at all?


Good luck!

Hi dfbowers and anyone else:

What kind of wire do you use for connections to pots, switches, and even tx, rx coils? I see red insulated wires. Is it multi or single strand? What gauge do you like?

Stuff I use seems to fight me...

Simon,

I have been using 22 AWG (stranded) from Radio Shack. I think it comes in a few different colors.

Finally I put a shield. Problems, approached a finger to 1 mm of the coil or the wire and the detector makes false puffs.

All is well connected.

What's happening?

magnetic personality, or nice sensitive detector!

Do you have the shield grounded as documented?

In mineral-free soil.

skip shield?

Mineral Free Soil, can be Wet Soil, causing higher capacitance interference with the Search Coil. Trees, shrubs, and vegetation can, and will cause problems. HF interference may (will) influence your MD via the Search Coil. HF interference is today a far bigger problem than it was in the past.

Why limit your search Coil to Ideal situations? What will you do when situations become less ideal? You will need two Coils, one with, and one without a Shield. If you want to go deeper, then why not build a larger Shielded Coil?

You will be gaining nothing by leaving the shield off, and loosing all if the situation becomes anything less than ideal. Concentrating on a GOOD Shield, has all the benefits and advantages that you will not want to miss out on.

Robert
