Troy shadow X5

[eclipse]

Sheesh this is the mother of all capacitors! I noticed relic hawk has the same big and ugly cap on the board. Any special reasons for putting this stuff there?
How the device performs on the field will get your answer if there are many interested people Strujas.. so any ideas how it performs, any feedback ?

[kt315]

Always thought that troy X5 is kind of Ferrari's appearance

Troy is absolitely accepting all wishes of folks. they asked at the moment:
1. full analog
2. very quick reply on target
3. manual ground balance
4. great sens as in 'oldie legendaries'
5. intelligibility on zink at nails

people has GOT what they did dream. there we see a situation that the brand is following ONLY folks wishes and certainly speedy droped out at MDs' market.

IN ISSUE. what REALLY strategy must be! folks wishes must been ignored! brands must following NEWEST SCHEMATICS' CONCEPTIONS in spirit ot the time. ONLY THIS IS UNLOSING REAL BEST STRATEGY AT THE MARKET.

this capacitor is keep-and-hold one as SAT in All Metal mode/channel. simply it is absent on the schematic, there is not this pinpointing part.

Totall CRAP !!!



Acting wise again!? Ha,ha,ha,ha!!!
Your presumptions here are totall crap, like always.

Troy Shadow story is quite different.
Still Troy detectors are top machines, no matter what some selfpromoting russian ignorants claiming arround.

Please stay on topic... nonsense will be deleted.

Many thanks Carl! Right decision!

Mrand thank you very much for sharing Troy traces with us! I had X3 which seems to be identical with X5. What i saw than is one splendid machine!
Is it fully analogue? I had impression it was not, although not sure. Few ic labels scratched/removed, also X3 has to many trimmers to understand without schematic. Now,thanks to your posts, many things cleared up!
Best regards!

Hi
i am a fortunate possessor of a troy X3.

excellent performance on Mineralized or wet land and first of all very, very light. The depth is not high ( 1€ coin at 20/25 cm depending of ground ) but the disc is good.

In the first 20cm of ground of my wood ( center Italy ) is a Killer for militaria.

i will try to post a photo of the pcb.

the coil is concentric with a electronic component in it.

Ciao

Hi folks,

Sorry to bring up this old post but I need some help from the gurus. I'm not proficient in electronics so please bear with me.

The thing is it's quite difficult to find good coils for the X5 and seems some people have had some luck using SEF (12x10) coils with the X5. SEF coil pinout is as follows:

SEF
Pin 1 & 2 RX 36,6 ohms
Pin 3 & 4 TX 2,6 ohms.

TROY
Pin 1 & 2 RX 85 ohms
Pin 3 & 4 TX 15 ohms
Not sure of this since my multimeter reads different values

To do this they seem to change C7 capacitor to something around 220nF and I'd like to know if this make any sense to you guys since as I said before I'm not very knowledgeable in electronics.

Thanks
Antonio

Further research before anything else.

hehehehehe... now isn't is the world too small?

Yes buddy, trying to research as much as possible not to screw up anything with my 4 feets

Take care mate

Hi everyone!
The other day accidentally my detector was run over by a car.
A board is safe, but some components are cut away. These components is lost in a place of tragedy in the field...
Due to the Mrand's scheme I have already purchase timer U1 and logic U3.
If did I get it right, capacities of C7 and C8 is 70 nanofarad for each?
But for me incomprehensible following nominal values:
R6-?
C3-?
C6-?
resistance of potentiometer T1 -?

Thanks!!!

[Whites]

On the Mrand's scheme R4 (on my board - R5) = 3К9, consequently for timer output frequency=37,44 kHz needs C3=2n2 and variable resistor T1=10K (by Mrand's scheme it is R7=100К). Frequency is reached by adjusting T1.
Here all understandable.
But I can not understand about R6 and C6. I am suppose that C6 required for the filtering of hindrances.
Consequently possible use 22n...100n for C6?
But what resistance of R6?
C6 and R6 are not present on the Mrand's scheme. But they are visible on my picture.They are connected to a 11 pin of logic HC74 - Clock input.
I am weak in electronics, please prompt me, who knows this theme..
Thanks.
Eugene.

C6 is .1 uFD
R6 is 1K low tolerance 1%

Don't get stuck on finding 1% resistors if you can not. I don't think it's too critical here. Maybe measure some 1Ks and pick one that is right on.

This is a very educated guess (i.e. I'm pretty sure without seeing the actual board).

Good luck Eugene.

I have recovered electronic part of detector and to my mind it works not bad.
Thanks to Mrand and aspecially many thanks to Technos.
Single, that embarrasses me, it is inconstant frequency which I measure on the output of U3. I measure in different moments of time and get difference +- 0,05kHz. I applied 1% tolerance resistors. Maybe capacity of capasitor are changes? Maybe needs tantal-capacitors? Insofar critical such change of frequency?
Thanks.

Maybe you should stop running over your metal detector with the car .

If it was me I'd look for further damage to the components that are still on the board. Surface mount components can crack (like when being run over by a car) and still remain on the board. These cracks are very hard to detect in many cases. But if you get a 10x eye loupe/magnifier you might see hairline cracks on the sides (not the top) of the resistors. This could be causing the intermittent problem you describe. The more difficult crack to spot is when it is under the component's solder tab (i.e. the edge) where it is hard to spot unless you remove the component and spot it on the underside. But usually when you go to lift a componet that is broken in this area they crumble immediately on the edge and you will know that they are broken here. Caps don't tend to crack in the middle (as they are thicker) but they can on the edge.

Here's an idea. If you want to/can finish tracing out the schematic for the community of the troy X5 (as the schematic we have is not complete), I will take a look at the board if you are unable to find the fault. Just pay the postage too and fro. I'm really busy for the next 30 - 40 days, but I hope to have a little more free time by then. But check with me first.

BTW, I have done a lot of work with SMT in a manufacturing environment FYI.
