RELIC HAWK

[amtech2005]

Hello Qiaozhi , Thank-you for the dollar conversion , plus add high over-seas shipping and we have a big over-priced Minelab !!

Will be a good deal for a local buyer .

Regards..........Eugene

Coil and shaft are exactly the same as on "Black Knight". Many simillar models made in China.
However; i am looking forward to see more details on that one.

Hi, I have $100 china metal detector. I have compared its circuit diagram with reworked Relic Hawk schematic and ... it looks very very much the same electrical and even more advance in favor for china. Can You submit any test results for 25c US in air for Relic Hawk. My china detector gets it within 20 cm. I am about to compare some electrical performance with Sterling as well. The curiosity is why detectors with nearly the same schematic and components may differ so much in performance. My bet is the coil and the some 3% difference in schematic. The question is Which part is so critical so it makes that giant difference between metal detectors?
Regards,

Can you post schematic (circuit diagram you mentioned) and detailed pcb picture of your China metal detector?

1020

I get photo from ebay. It has many names but the model number is 1020
and it has always the same appearance and coil. It has LCD display and it has linear indication for phase shift and depth (signal strength) you can adjust the sensitivity and software filtered discrimination. As I said analog part is very similar to RH. I believe that it is deliberately under design to support 9V battery and due to marketing reasons.

1 to 2% could easily be the difference in coil shielding. What is the brand name/model name of the china detector?

Why ?

Hi,
Yes tough task.
Look similar problem.But on this only one wire were broken on outside /coil/connector.Maybe some short there occur.
I can measure that those two diodes in sound stage shows 330!Other pair around 4053 shows 660.Maybe they burn too or took some damage.
The problem is that sometime this bsr52 still get hot.
2,5V ref. is ok.I have it.
I will try to measure those 3 ICs output today.
Thanks

Nothing special in those coils. Last summer i bought several Minelab coils. Some of those made by Minelab and some are Excellerators. Nothing special.
Those ARE exceptionaly good coils, but nothing uncommon or secret at those.
TX=1mH, RX=15mH, TX=2-3ohms, RX=30-40 ohms.
Recently i adapted ordinary handmade ("Serbian Most Wanted") to work very well with those Minelab coils. Nothing specific that i had to do than.
So i think that problem is still in schematic we have here. Still not accurate.
Something is missing or put incorrect in schematic.
Regards!
