COMPLETA tgsl. Falta y reel Construir en breve la Falta de Circuitos Integrados. Espero Que funcione de Cuando Usted Toma la Batería.

Nice work @Virdi_248!

You may try Mouser Electronics; www.mouser.com for the Chips, but they may still not have the LM308 in stock.

Interesting how many people seem to want to use a fuse as protection device. In this kind of low current applications, a fuse will always be too late. A DIODE in series with the battery (lowers the voltage with about 0.65 V), although giving rise to a slight loss, gives far more protection. Especially in Metal Detectors with interchangeable Batteries. People often make battery polarity mistakes when swapping new batteries. Even a fuse will prove to be worthless in such a cases, and far to slow to protect those sensitive semiconductor components. Preventing a fire from starting, may be considered to be the main motivator for the use of a fuse. Like in your computer and magnetron oven. Electronic components nowadays have a relatively long fire retardancy time, and a "slow" fuse will in most cases work out just fine then. Have you ever heard of a Metal Detector setting the place on fire, for I have not. And using a Metal Detector in a with Methane Gas infested mine, probably won't make much difference too. For a person who lives his or her life with this kind of stupidity, will most probably already have been killed on the way to the mine in the first place.

What will it be, ... Fuse, Diode, Fuse, Diode, Fuse, Diode, ... what the hell, ... then just use them both if it makes you sleep better.

Regards,

Robert

Interesante cuántas personas parecen querer utilizar un fusible como dispositivo de protección. En este tipo de aplicaciones de baja corriente, un fusible siempre será demasiado tarde. Un diodo en serie con la batería (baja la tensión con alrededor de 0,65 V), aunque dando lugar a una ligera pérdida, ofrece una protección mucho más. Especialmente en los detectores de metales con baterías intercambiables. La gente suele cometer errores cuando se cambia la polaridad de la batería baterías nuevas. Incluso un fusible resultar inútil en estos casos se lento y lejos de proteger a los componentes de semiconductores sensibles. La prevención de un fuego se inicie, puede ser considerado como el principal motivador para el uso de un fusible. Al igual que en su ordenador y horno magnetrón. Los componentes electrónicos hoy en día tienen un tiempo de retardo de fuego relativamente largo, y una "lenta" fusible en la mayoría de los casos el trabajo salió bien entonces. ¿Alguna vez has oído hablar de un detector de metales establecer el lugar en el fuego, porque no tienen. Y el uso de un detector de metales en una mina de gas metano con infestada, probablemente no hará mucha diferencia también. Para una persona que vive su vida con este tipo de estupidez, es muy probable que ya han sido asesinados en el camino a la mina en el primer lugar.

¿Cómo será, ... Fusibles, diodos, fusibles, diodos, fusibles, diodos, ... qué demonios, ... a continuación, sólo tiene que utilizar a los dos si eso te hace dormir mejor.

I am not a great expert in electronics, only I defend myself. Thank you for the information of placing a diode to protect the circuit.
The circuits integrated already I have them. They are these.

Hello, recently I made tgsl and data for the probe 5.8mh 6.5mh in the air and got good results on the ground, especially on the grass playing and restless is impossible.

[Orbit]

balans uticaja zemlje je u redu radi relativno stabilno samo gde nema trave pogotovo ako je trava mokra

[Orbit]

Where no grass is relatively stable and where the grass is wet it is impossible to work with tgsl the impact of the country that I have everything set up properly

[Orbit]

And it happened to everyone who made it why it is happening at all.

Tgsl not good at all and my translator

hi guys
i was wondering.. if posiition of coils has great matter than is it true (just like ivonic said) that it should be nulled in same direction? i mean when i nuuled both coils nulling was in same direction but when i trying to balance coils then i must put them nulled in same direction..that means i must turn one of coils upside down to get same direction of nulling ..am i thinking right?
regards to all

Sounds like you have two wires reversed, or just flipping one of the coils over will achieve the same results. The easy way to tell is listen for a double beep.

One question I have for everyone. Ivconic recommends winding the coils in the same direction paying attention to "start" and "finish". Does it really matter or is it just to get the polarity correct from the very beginning? I have never paid much attention, but just flipped one coil if polarity is wrong. I can't see any difference other than just polarity.

I have proved my tgsl and it works. The bobbin that I have constructed is very bad. I detect tin of refreshments to 6 inches and a currency of Euro to 1 inch.

In addition I have tried with two bobbins of another detector that I have (gary touches 2) and it detects a tin of refreshments to 10 inches and a currency of Euro to 2 inches.

With thread of so thin copper it is very difficult to make a bobbin good.

Where they sell the original bobbin of the tgsl?

Hi @Orbit,

I think you have your coil shielding all wrong, or it may not be connected properly. A properly shielded coil should not behave like this from what I have read, and seen on YouTube. Please take a look at this YouTube Video:

How to Repair Faulty Metal Detector Coils (5m42s):

I hope this will help you @Orbit, for your problem dose not sound TGSL circuit related at all to me?

Regards,

Robert

Tesoro has the original coils or you can often find them on Ebay.

The uMax series are what evolved from the Sabre series, so coils listed for the uMax series should work. The original coil issue was the 8" Round Concentric.

It is not enough for your coil to only have good detection depth. You should also have good discrimination. Having an "original spec" factory coil can be a very good thing to get things going.

[Orbit]

Thanks Robert. You were right I am a coil, the probe took one second when I opened the Faraday cage at th was not connected.

Since we did not probe that had a probe in the 60 th round and round in rh 6O wire 032mm diameter 32cm probe the change of 22nf Capacitors for him, I put 68nf that frequency was 14.4 kHz.
