LOOKING FOR GOLDSCAN 4 Schematic.

[Max]

Hi Max,

I saw a person that claimed he has maked GS4 that can detect large objects at 5m with 1m x 1m coil!!!

I doubt if GS4 can detect so....!?
Your opinion..?!

Best regards

Hi 1843,
I don't know real potential of GS4... cause ended experimenting with.
I know is a powerful PI and with small coil is the best solution on the beach I've ever seen, really deep search.

I think that GS4 have an extremely good S/N and could beat e.g. delta, xr-71, PS2 and even lorentz with right coils!

But 5meters seems big distance...object would be really great (1mx2m or more) I think could reach e.g. 4meters using 1mx1m coil and maybe 5m or 6m with 2mx2m coil. Just guesses.

Kind regards,
Max

Hi 1843.
If you modify it a little you can locate big objects at big distance.
So you must change the TX pulse to be 150.... 600 us (typical), delay >30us and Frewquency lower to 400 Hz (for better battery life). But for large objects i thing that Delta is better (good depth and VERY stable)

First, The DEEP(PI) is complex from good L Q factor, max pulse voltage and Pre-Amp amplification
and second - the good Schematic give stability, noise "reduction" and user interface...

Hi 1843,

be patient....drawing a proper schematic in a CAD program is the first step in making PCB's. Chris [/QU
I NEED PCB FOR GOLD SCAN 4

Hi, I really want to know what's the advantages of this MD(Goldscan....)?
would you please inform me? Is there any genuine detection range chart?
I've heard only it's an ordinary MD with its' own errors and not powerful.

When I Get Home in a Few Days I will post a 6 page PDF That has Schematic and PCB Board Photos that you need for Goldscan IV . Unless Someone Beats Me To it , I got it from a Russian WEBSITE. ANYWAY !! , ALSO CHECK THIS OUT !!! WHATS FOR SALE !! at http://www.tanyerielektronik.com/ I guess they are just trying to make a Living !!!! TAKE CARE All , EUGENE

Erolunall, Your right It's the same as mine also. It seems to me there should be Plenty of information enough to make a PCB board !!! There was a Post from a Russian site that had 3 images of the goldscan IV PCB board in different colors . So I am Searching again the .ru site links I have saved. Take care Eugene
