I made some huge progress!
Previously i said no more Classic III!
It was because Tesoro Golden Sabre works from a start very good.
I am still very satisfied with it. Very good detector!
But, since i do have Troy Shadow X3, but unadjusted....i was
thinking to test its coil with Classic III, cose resistances on
TX and RX almost matched with original White's coils....
And it was good guessing! Works PERFECT!
The very BEST performances on coins i ever saw!!!
So, Classic III with Troy X3 coil is winning combination!
Although i made few changes, changed some capacitances arround
oscillator and few resistors....It was experiment, and it worked!
Yesterday i tested it on real field. I picked up roman location.
It was better than i expected.
Depth is great. Found coins (0.8cm-1.2cm) at 20...28cm in the ground!!!
Coil was in the air, some 5-6cm over the ground! Sound loud and clear!
Discrimination is also excellent, on smaller items.
Cant discriminate bigger iron items well. But this is the case with all
detectors i tested so far....
Main thing with this wild combination is stabillity; most stabile detector
(with this coil) i ever saw!!!? I can punch,slam coil on some rocks,trees..
still remain stabile, no sound. No matter ground was wet,still no false
signals!
Best sensitivity in all metal mode on iron. Detected iron arrow (8cm long)
at 60cm distance....VERY LOUD AND WIDE SOUND!
When disc is ON, and adjusted just about to make "cracky" sound on iron,depth
on coins remains the same. No changes. Very,very deep and stabile.
Comparing to X-Terra 70 and Minelab Musketeer Colt (i prefered it until now)...
....no competition! Both Minelabs are out of competition with this Classic/Troy
combination! The very BEST and i mean it, so far i had!
Of course, most of the tests i done on coins and small items.I am only interested
in those. Digging huge holes is not my favorite...
What can i say more? Absolutelly no drawbacks! I havent noticed neither one!
Next few days i'll perform more comparsions.I intend to take Sovereign GT and
DFX with me on the same field and compare their performances with this combination.
Maybe sounds funny,stupid, but i think it gonna beat those too! Its because i done
a lot of tests already in the past and remeber some results..
What should be my conclusion here?? I guess answer is very clear!
Most important is the coil itself! MAX read this twice! I think that you dont have
problem with your Bandido, but with coils you used with...
Never mind you maybe tested it with original Tesoro's coil.....it will need more
precisely to be matched with coil you picked up. How? Simply you have to experiment until
your hair drops arround you! Capacitances in oscillator should be matched as close as
possiblle!
Also George Payne was very right! Now i do understand him very well!
"...Of course real ground conditions do not behave like pure ferrite. When subjected
to a detectors magnetic field small currents begin to flow in the soil. This will cause
the soil signal to be displaced slightly from that of pure ferrite..."
In the past i made crucial mistake when nulling coils; i used ferrite rod and tried to
achieve absoulte "rejection" of ferrite, along with gaining least voltage i can on RX
coil.....Taking ferrite as reference (middle point of phase) was my mistake!
Reading Payne's theory many times i realised his point. Should BE DISPLACED slightly, just
about to react on ferrite,but weak, very weak....He mentioned some +5 degrees. I agree.
I do not have instruments to accurately measure shifting but now i can use experience and
scope (old,rusty)and achieve this.
This is just what i found out testing and measuring Troy coil connected on CL3, when
adjusting capacitances arround oscillator...!
So Max, what you have to do is to pick up any suitable coil for your Bandido, connect it on
detector, switch ON.....use ferrite rod, few coins and experiment,experiment,experiment....
Change slightly capacitors in oscill. by adding or substracing few nanoFarads...until you
gain best discrimination with it.Depth also... I am sure you will be amazed with it after
hour or two...
Any descent detector can do the job! It is just about coils! Remeber this!
This will open quite new inetrests...i guess. I am planing to buy few Troy's coils more.
I'll cut one and count windings, measure wire gauge.....try to copy it. Not to sell or
distribute those further...but to learn more about this subject...
Now, i can only imagine how 19kHz coil can work that good on 6.3kHz machine...!!????
Hah!? Any ideas?
Heh!Heh!Heh!Heh!
Dig it yourself!
Regards!
