TESORO GOLDEN SABRE

Doesn't matter. Just hook it up and null coils. If u get a double beep reverse connections.

Here are all the details very well explained.
It is imperative that you read this.

This Is My Coil So now on the board Tgsl Edu
witch one The Tx Start and Tx End
The RX Start And Rx End

[paku]

The coils are poorly void. If you do not have an oscilloscope, you must use an AC voltmeter and measure the voltage at the output of the preamplifier RX, (PIN7-LF353). The Voltage must be around 100mV. We also have to shield the two coils, that are well balanced. The space between the two axes of the coils should be at a distance of between 25-30mm or so. You certainly have a greater distance, so the cancellation is inadequate. You must read with great attention all over the forum post TGSL, and sure the detector is going to work first. You the first thing you have to do is learn to override the coils.

so on that my picture is that true connection or dd coil or not
the
Start TX End TX
Start RX End RX
or i can connect the coil booth

i have fixed shielded

Coil

So it has to be your coil more or less. Compare the distance of your coil axes parallel with mine.

Its Look Like This On Coil TX And RX Connection Or Rong

By the look of your coil, it is not nearly as balanced as it should be. The overlap looks far too wide for a well balanced coil. As a result of poor balance, your preamp is saturated, so the subsequent circuitry picks the power supply fluctuations, and amplify them in a relaxation oscillation manner.

Fix your coil first. You must achieve below 100mV on preamp output to claim it balanced.

As I see your Tx coil is unshielded. Bad Idea. Foil shield drags a phase some 10° or so, but if both coils are shielded such drag is mutually compensated, and it makes sense to shield them both.

Hello All Why I Get This Error

[eduardo1979]

The LM308 can be damaged, or placed upside down. Try a new IC. Before turning on the detector, the coils must be connected. You have to measure the voltage 8V and 6.2 V. Greetings.

Why This IC is Hot And I Get Only Sound Very Speed Beep
or i get rong on my coil conection

[eduardo1979]

I recommend metal box.

[paku]

i want put the mainboard to my box so i need use metal box or plastic box

[eduardo1979]

4-----8 Ohms
0,5---1W

What Is The Best Speaker For TGSL-EDU
i buy TGSL from silverdog but it just beep speaker
so i want change it what is the best recommendation From Guru-Guru In Here
