threshold

[quizpro]

I never use my threshold could someone tell is it better to use it or not use it. Thanks. quizpro

If you have a threshold based detector it is better to have the threshold sound at a barely hearable hum. You will have to be in all metal mode of course or have the pinpoint button pushed in. Threshold is an aide in pinpointing and for hearing smaller/deeper items when in all metal mode. Wish I could explain it better & hope that I didn't confuse you any more than you were to start with.

You did good on the explaination on the threshold, I would'nt have touched that with a 10 ft. pole, you are braver than I am!

Thanks buddy, some things come automatic to us old timers such as setting the threshold, sensitivity, discrimination, ground balance, etc. because we have been at it so long but not so easy to put into words as to where it makes sense. Ahh shucks I am not that brave just have wide shoulders . Good to see ya around Hombre, I am back to swinging a Tesoro again & will be around here more often. (Just can't stay away from the Tesoro's machines, got em in my blood I guess).

Barely audible threshold is the normal setting, turned past that to a loud hum is supertuned.

Warning! threshold turned far to the left below audible setting will kill your depth!

On many detectors (including Tesoro) the threshold can be thought of as a second sensitivity control.

I wondered why my detector didnt seem to go very deep.I will try that when I go out again.Thanks. Quizpro

 

[quizpro]

That sure helps to know I can get this detector to go deeper. Maybe Ill find more in my yard if I do that. Thanks. Quizpro

When all else fails, read the instructions.

Good advice, I believe quizpro has a Conquistador if so you can read the user manual to it here http://www.tesoro.com/info/manuals/older/conquistador/
if it is a Conquistador

I'll add my two bits. I've read somewhere where the models with a threshold adjustment perform better in discrimination mode if the the threshold hum is set at an audible (can be soft) level even thought the disc mode is sllent.

You are correct bill.
I'm not sure how many of you used the old short wave radios, CB radio's or police scanners, but they had what was called a squelch control. When the squelch was turned up, it eliminated background hiss by silencing it. The further the squelch was turned up, the stronger the signal required to break through the squelch.

Threshold is basically squelch in reverse. When threshold is turned down, it takes a stronger signal drive an audible tone.
You will miss those deep signals even though you may have sensitivity maxed out.

Don't beat me up, this is just a crude analogy.

I am not going to beat you up on your analogy as I have used the same cb squelch statement many times to explain the idea what threshold is. Very good explanation Randy. Steve.

Not a crude analogy at all, ..... a very good analogy.

Then you must not be ground balancing your machine either. Tuning theshold by itself doesnt do much if you dont haver your machine properly ground balanced. Your ground adjust could be way off, further giving you very poor depth. I would suggest you learn how to set your threshold, then ground balance your machine properly. You may be amazed after that, how deep your machine really is. Then check your GB setting from time to time, but sure you have not bumped the control knob.
