IGSL

On second thought... maybe you will not need to tune up capacitance with RX coil.
Why?
Simply because now at IGSL you have adjustable amplitude at TX.
Adjusting it a bit, you may match the "ranges" and everything can come to it's place.
Simple facts to know: changing the amplitude will affect frequency at IGSL, which will indirectly affect RX tune up.
Change amplitude in very small steps.
Use multi turn trimmer for 200ohms.
Play a bit with it before decide to tune capacitances in RX, because, most probably you will not need to do that later...

That is good new about the Tesoro coils, I bought a Vaquero yesterday

Also despite the musketeer winning the poll we had, only 1 person has ordered a musketeer kit , a few people have both boards but we have only seen TGSL versions completed - I think the higher cost of purchasing the minelab coil compared to a tesoro coil may have put people off , so hopefully the good news about the tesoro coil will help

I have reduced the musketeer kit and added a musketeer pcb at just £5, get them while you can

Minelab coil is expensive same as newer Tesoro coils. Not much differences in prices.
People will order pcb's in time. By now most of them are waiting others to finish their detectors and report results. IGSL is not an easy task for majority.
But it is worth of invested money, that's for sure.
...
So you bought Vaquero!
Nice!
I have two friends with Vaquero's, those are very happy with it.
Which one you bought? "Germania" or "USA" ?
We noticed that those two are a bit different in behavior.
...
Now, since you have it, you must obtain coil connector for IGSL , to use Vaquero coil with it.
If you face some problems when using that coil with IGSL - pay attention on RX cap and try to adjust it a bit. Adding or subtracting from 15nF will tune up RX coil to match exactly.
As i recall... it will need a bit less capacitance than 15nF to match exactly the phase. Something between 14nF to 14.7nF.
Use Quiaozhi's calculator, it is accurate.
With TX part you will not have problems at all.

Aha! I just recalled one nice thing too!
Bingo!
New Tesoro coils for most of new models are also having pretty same (if not exactly the same) specs as Musketeer coils!
I checked Vaquero coils; 1mH and 15mH!
So... Vaquero, Cibola, Tejon etc..etc.. coils also can be used too!
How about that?
I just revealed the important "secret" here!

Hi
Is there any of you here modified the TGSL to use the musketeer coil, Im thinking of trying it but i would want to switch it some how so i can use both types of coils for experimental purposes without damaging what already is quite a nice bit of kit.
Thanks
Dave

That's easy task now.
Just see how is done at IGSL and "transfer" it to TGSL.
It will work, don't worry.
All you have to do is to change oscillator stage and nothing else.

Hi I asked this a wile ago but still not sure

On the tones in IGSL there are 2 diodes and you choose to connect them to 3 pins on a chip. We know 3 into 2 dont go. There are a lot of permutations here 2 ^3 ?

What is good choice here pls.

Anyone you like. It doesn't really matter.

You choose 2 of the 3
There are 3 possible tones, you choose the 2 that sound best to you
I used D1 to pad 9, D2 to pad 5

yes i have seen this fact while comparing the coils but i was not sure´because of 4pin plug at them
yippie

the shield is connected in coil housing right?

at the "older" models the shield has one "extra channel" in cable which goes up to box

Yes.

thanks ivconic you are a good motivator

with the coils i handle it like you have written i have an orignal tesoro here for compare them with my diy it curious that the commercial one only does perform 1-2cm better than my diy (fast made and non precision)
price difference to my diy more than one hundred euro for list price

for the musketeer coil:
i ask a dealer here in germany he says me that the good ts1000 minelab coil is no longer produced any alternatives for the future?

That's the regular and most common excuse from dealers which have nothing to offer!
TS1000 is most produced coil at Minelab, ever!
Even if it is discontinued (which i am not sure) still there are plenty left in reserves.
Search at other dealer and you will find it. Search at ebay too.
Alternatives ... there are plenty! Don't worry!
Exellerator coils for Musketeer... let's see: 32cm, 36cm, 45cm! All those available.
I bet there are also other smaller producers which will offer such coils.
Bulgarian colleagues are very fast at such matters and capable to produce any kind of coil in no time.
Maybe is good idea to offer such smaller series to some Bulgarian producer to make?
Also there is one producer from Ukraine, can't recall it's name right now...

hello im short before finishing my igsl musketeer
it seems that some have problems when finishing their units

i´m frightened that this the same at me

can it be that there are on every versions tesoro coil / musketeer coil version
are options an the board the partlist for my musketeer version has less parts as printed on my board so that i have to leave some points free?
for example the is printed the part number Q3, Q3 and at another place the type BCxxx
or a printing for a cap named as spare
for sure i will compare with shematice but soldering strictly after the printing and partlist confused me a some little points

so i think i will post a pic this weekend (i hope my works)

and others can do it to there is nothing magic to upload a picture

It is always like that; some people do make it proper and their devices start working nice from a first switching ON... and some people do miss something to do right, and their devices are not working nice from a start.
Don't worry in advance!
That's why is this forum for - to solve such issues.
Finish it and than we will see.
Just look TGSL thread! First TGSL started back in 2007. and even today some people can't make it right!
That's why i involved second version ("Musketeer coil" version) - to make life easier to those which are not capable to make good DIY coil.
Musketeer coils are not so expensive and you can find it almost everywhere, in almost every md shop and service.
And unlike the original Tesoro coils (for TGS serie and other oldies) - Musketeer coils will perform much better and deeper.
Involving second version seems not good enough; because some people still insist even to make that coil too!
Ok, that's very nice and enthusiastic, but i don't see the point?
It is much better to buy one and than to use it as sort of "reference" for all further works.
For dedicated DIY'ers there is still first version for TGSL coils...
Despite that, i still made few DIY coils for Musketeer, just to experience that too.
It is not hard task, not harder than making TGSL coil.
But, keep in mind that before i started to make DIY Musketeer coil - i already had few original coils to compare!
....
If you take a look on TGSL thread, read each page and follow all the "history" there - you will see that pretty same story could repeat here too.
It is always like that.
Process of making, adjusting,testing..... various issues that may appear in process of making... - the same.
More pedant and patient DIY'ers are always getting the proper hand made and success at the end.
So don't worry, just make it.
Each one of you will finally have good hand made.
Some of you sooner and some later.
That's the beauty and that's the hobby.
And this forum here is to help you.


P.S.
If i turn back in the past and count all my successful and unsuccessful hand made, among all what i done so far... sheesh!
Relation would be 70% : 30% !!! (70% stands for bad ones!)
See? Yet i didn't give up so far!
Ain't that real passion and dedication?
