TESORO GOLDEN SABRE

[Davor]

I didn't notice any depth loss with larger capacitors and fast waving, only a non-motion-like pinpointing capability which is very good. As Silver Dollar says, going lower is best if op amps are replaced with low noise ones, preferably with low 1/f corner frequency.

ok i will try use 4.7uf so i use 4 pcs 4.7uf like

[paku]

can any one show me sample picture on board how to put that 4.7uf im relly dont know how

[Silver Dollar]

Well with 2 caps in series the final value is 1/2 so you need to use 2 10 uf caps to make a 5 uf cap.
To make them bipolar you connect the negatives together like this;


(These 22 uf's would give 11uf)

[paku]

so the polarity is same ?
is that look like this bro
this is my board

[sinclairuser]

that looks right, please give up the winstons mate, those things will kill you(trust me i know), i gave up 6 months ago and now my chest has cleared it feels like i never smoked, a good tip if you stop is put the cash away, like you are still buying them what you save will blow your mind.

[paku]

ok bro i have try to stop very hard to stop that bro
by the way thanks for give me the advice i will try throw away that wingstone

witch coil is better for TGSL edu
Double O Coil
Double D Coil
Concentric coil

and witch coil from tesoro model, the best for TGSL edu

Different coils do different jobs. Small coils best for small items or trashy sites. Larger coils larger targets deeper but less sensitive to small items. 10"-13" seem like a good compromise.

Concentric coil better pinpointing

Double D Coil best ground coverage

Don't know which factory coil is best maybe someone else could chip in as I would like to know

homemade coil for TGSL must use 4 wire or 5 wire

[golfnut]

With a larger cap you extend the gain down towards DC. So will be able to locate and home in a bit easier. esp with a dd.

The inevitable trade off is the extra noise due to the extra BW.



The other penalty is the rate of change of ground signal is slow and so extending the frequency down you boost the gain where the ground signals come in.


You mentioned extra chatter, could be a mix of the two.

Paku,
USB cable has 4 wires and shield - so 5 ... you can use 5+shield also ...
Or you can use less if you use one of options for connecting to GND in coil.

Paku you can read Don's manuals on TGSL coil making

Guys,

what power source are you using ?

I have used 12V 1.2Ah sealed lead acid battery... I am looking for something smaller / lighter with same lasting

[Silver Dollar]

3 of these are small and light. They are probably not 5000 mah but more like 2200 mah but
still a good choice.

You can find the battery holders on Ebay too.
