TESORO GOLDEN SABRE

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

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

[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]

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

[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]

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

[paku]

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

[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.

[Silver Dollar]

It depends on your opamp. It opens the input frequency down from 7.2 hz. If your amp is noisy
down there it will get chattery. I went to 5.7 uf with a bit of depth increase and no significant
chatters. You have to sweep slower with larger values there or you'll miss some targets. It's
best to stay with 4.7 unless you have special needs...

[paku]

so witch one is better for stability
4.7uf
10uf
22uf

[Silver Dollar]

The original was 4.7uf nonpolarized. Zoom in on this picture to see;



The 22 uf's give 10 uf and thus lower the bandpass frequency. That can get you more depth
at the cost of more chatters. It was a mod by Eduardo...

[golfnut]

If u put two 10uF in series you get 5uF - to make them bipolar rather then polarised you need to put the negatives together or the positives.

If one pos and one neg join, it is is a 5uF polarised still.

[mschmahl]

If you connect two 10 uf back to back you get 5 uf bipolar. So you can use one 4,7 uf bipolar instead of two 10 uf normal electrolytic caps.

[paku]

i have see on TGSL EDU schematic have 10u on that schematic why on the silk board 22u and how can replace with 4.7u bipolar is same electrolytic caps right
