Barracuda Legend Kit Problems

[ripsdevala]

Thanks tim, will create one and report here next week, the thing for now is my bara too sensitive to ground, sometimes it make a false signal. Just swing hours ago, at sugarcane plantation, nail again.
Better wait Qiaozi new plan i think.

Some coil info.

Never feel temp below 20 here in javanese, keep the update tim, i will keep following, basket menu will be my favorite, looking averywhere and get no tutorial about it.

Not yet. It's after midnight here and 3 degrees outside. I have a roll of .5mm&.4mm enamelled, and also another small coil made from .4mm plastic coated wire. Also waiting on (hopefully) better components- Philips 5534ANs and ST MC74HC17B1s to replace 40106. A small basket-weave coil is also on the menu.
I do get some falseing from loose cable on the end of a swing, when I have the threshold cranked too high.
Sadly the 266 coil was better on the table than across the floor......
Still also waiting for LT1054 to replace 7660.

What a good distance, i have 30cm diameter 30turn 0.5 wire 2 ohm+ and its not better than 25 turn (maybe) 0.5 wire 1.5ohm, 25cm max for coin, sharp tone.
Btw, do you already test it on the ground? Did you get a beep on the ground on every up and down, or this is normal.

Well, the Baracuda journey continues. Tonight I tried a schottky diode across my TIP127, as suggested somewhere, which has substituted my 9640 during fault-finding. Neither made any difference. Tried LT1115 as a suggested alternative to 5534-did not work.
After tinkering with damping again, I ended up removing 750R and going back to 330R, after re-setting offset for best performance.(On the 455uH twisted cat5 coil)

I had a 10x5 elliptical laying around, that I made originally for the Surfpro, but it was useless on that. From memory it was 30 turns of .25mm enamelled, shielded top and bottom with sheets of mylarised plastic (powdered milk packet). It is just a piece of 15mm ply with a groove cut around it. 266uH & 4.5 ohms at the board.
I thought what the Hell, and tried it.
Now I detect an Oz 5c piece at 12 inches, and my 1.7g flour gold at 4 inches (just). Air test under the flouro light, with the TV going, and junk all over the table.
The next instalment will be re-damping and re-ofsetting this coil........

Yes . If you search IDX,Classic, Classic ID. They are based on the same platform(?). I am considering buying a ClassicSL, and doing the Mr Bill mods(search classic).

DIY is the only option I have, the price after tax, custom and other gov term will make me cut one month work without pay bills and eat....

Look very promising MD this IDX, why there is no main project thread for this, there should be a reason.
Can I use this IDX pro thread to build one

That's a wild looking weapon ripsdevala! Is that a pinpointer strapped to the side?
I am considering the IDXpro from Silverdog. Apparently it is on par with the TGSL.
The Compass 94B schematic I posted back a bit ignores all small iron but sees very small gold etc. It is induction balance 100kHz. They excell on trashy areas, and are still used by many around old buildings etc. My original one I use daily.

Yeah I attach pinpointer there, too difficult to find tiny metal without it.
IDX...compass... le me do some research

If you build IGSL and use minelab style coil. You can get real 2 tone, iron reject and nice depth.
I have one I just finished that I'm putting a CZ coil on to go deep...

I see, home made coil is the only option here, hope can make one with the tutorial
