I assumed that but wasn't so sure..
I have it on my PC for longer period. But am not an expert in working with it.
So far i only transfered few shapes to Corel from it.
Man simply can not have enough time to learn everything....
Again; SPLENDID job Selim!

i´ve waiting a long time for this version now i dont have to fit the images into paint for saving thx selim

After everyone has built their IGSL and are hunting happily, I would be interested in seeing a version of it with a single GB channel -- for simpler usage and simpler PCB.

BTW: can anyone explain how the two GB channels might be put to use for hunting?

(I guess you could use one to hunt for ferrite by intentionally not ground-balancing???)

Simon you should make it... to understand a reason for second GB.
Second GB was compromise i must done.
Initially it was only one GB. Than i faced problems.
Adjusting GB to suit NF channel - not suiting F channel!
For example (i already posted this) if GB is adjusted so to NF channel fully reject ferrite - than F channel is still not rejecting it completely!?
And if GB is adjusted so F channel to fully reject ferrite - than NF channel is "over grounded" and there is good chance also to skip thin silver and foils!
I guess it could be done with one GB channel.
I had to experiment much more. It was much easier to me to simply involve another GB!
Sweet and easy!
PCB is not so larger from what it can be with one GB. Handling is not so harder....
But most beautiful thing is in fact that now, with second GB included, new probabilities occurred!
If need; now operator can adjust F/GB so to accept even some minerals. Lower pitched audio will than indicate presence of minerals in soil.
By no means, this will not disturb accuracy of NF block functioning.
So.. compromise to involve second GB - turned to additional advantage!

Make it to understand it. Otherwise we can talk bare stories forever...

".....If need; now operator can adjust F/GB so to accept even some minerals. Lower pitched audio will than indicate presence of minerals in soil...."

This is not that "naive" and irrelevant as maybe looks!
More experienced prospectors do know very good; that, often, smaller coins (especially golden ones) can be hard masked with even smallest piece of hotrock or mineral!
That's why, experienced prospectors, usually DO adjust GB a bit loose on their conventional detectors, to diminish chances to miss such finds!
As time goes by i am noticing more and more prospectors to adopt new searching techniques.
Most noticeable is exactly what i explained - loose GB and erratic behavior of conventional detectors.
IGSL will not act erratic because one pitch will still go on stable and another pitch can be manipulated either way - by desire and need.
So if prospector already know that on some soil he can expect hard masked finds - he simply will loose F/GB and further will pay more attention on lower pitch at audio...
Because; at such situations, if F/GB is adjusted a bit loose - both pitches will occur. Higher pitch may be erratic and with spits and lower will clearly indicate presence of hotrock or mineral near by colored item...

How do you open the Cracked version in the file to work? I could only get the Demo version to work doesn't let you save, copy, etc.

IGSL

I am working on IGSL Musketeer version, and am using 200ohm pot for P5 (Ivconics has 220 ohm). I cant get the voltage above approx 2 volt. on osc. I am using homemade coil. Anybody have better luck?

Only 2V !?!
Check transistors orientation, maybe you reversed some?
Give here more details; voltages, coil specs...etc..etc.. (resistance, inductance..)
One more thing: turn 200ohms to middle position before you switch it ON. Because if resistance is to high - transistor will stay "choked" and will not start to oscillate..

IGSL Kits are ready

All parts are in and I'll be bagging up a few kits over the weekend

I have added the kits to my shop so if you want one they can be dispatched on Monday

happy hunting over the weekend

I see -- extra controls can be useful if you know how to use them. I figured 99% of time I would probably set the GB controls the same and just use different DISC settings. I'm surprised you had a problem with single GB channel -- it seems like it should work in principle.

I look forward to hearing more experiences of how people use the IGSL for actual hunting, how they like to set the controls based on their experience.

It is a cool machine in any case.

Didn't dfbowers have similar problem at first? Maybe he found what the problem was....

Yes, IGSL is just simple analogue design, but it is offering wide choices to operator.
Kind a "open" detector; you may adjust it however you want.
Doing that you can cover more situations at real soil.
For those already used on TGSL it is enough to fix GB's and adjust F/Disc to zero and NF/Disc to ... let's say "3".
Later, as experience and habits grows; user can experiment with wider adjustments.

I'M waiting to see if DBowers or someone else who is winding musketeer coils comes up with something, meanwhile I'm stumped! I wish I could go hunting with my trusty TGSL but the last three times I went out to my favorite spot, the mosquitos are so bad I had to turn back. Deet seems to be useless anymore!

You haven't provided enough infos here... maybe you have some trivial problem...

IGSL Musketeer coils

You haven't provided enough infos here... maybe you have some trivial problem...

1.01 mh TX coil, 14.73 mh RX coil, 8713 TX freq, 4 V TX amplitude- 2v x 2 divisions, US quarter -3" steel pliers 4". Will beep 2 tones low steel, high- non ferrous. Seems to lack tx power. ground balances set midrange, tried different settings for threshold pots, set temporary null just as I did for TGSL coils- but power output is very weak. checked R values around osc. circuit, and transistors are orientated just like Eduardo board pcb.
