Deleon question

[Neil]

When in the all metal mode are you able to completely silence your threshold by turning the dial fully counterclockwise? Mine goes real faint but I can still hear it. Just curious on if its set correctly.

Hi Neal.....

I don't understand why you would want to silence the threshold, I set the threshold to a low level hum on all of my detectors that have this feature. My wife owns a Deleon and I borrow it once in awhile, it's a nice lightweight TID machine but the threshold all-metal is a little too fast in it's auto tune function. I have no problem pinpointing in the motion Disc. mode by eyeballing the coil as I advance the coil over the target with the Deleon. One of the use's of the threshold all-metal is in areas that have few and far between targets, uneven terrain like a plowed field or just not wanting to overlap the coil so much in the Disc. mode. Then when I get a hit in all-metal ..... I just flip the toggle switch to Disc. mode to check the target out.

Hey Randy,
I don't want to silence it I just want to lower it even more than it will go. It might be the black widows I use, they really block noise well.
I like the threshold and the all metal mode but I want it to be just a murmur, a slight buzz but it wont go that low. Don't get me wrong, it will turn up way higher, it just doesn't lower enough.
Im thinking theres a pot inside that I can do it myself but wont open it up unless I was told where it is as I don't want to mess with the wrong one.

I will drag mine out and check it out for you latter today. This is my all time favorite Tesoro.

From the earliest days when we had Metal/Mineral Locators, then morphed to the name metal detectors, we have had a control, properly named a 'Tuner' control that is used to adjust t a slight audio hum ... better known as a slight Threshold audio. In more modern designs, sometimes it is still called a Tuner while other makes and models just call it Threshold. The concept is the same, to adjust I up until you hear a slight audio hum.

There is a buzz present behind the threshold, I think that is what you are hearing is the buzz, turn it up for threshold.

I know what you mean about the buzz, I think that is the beginning of the threshold though. When hunting with it in all metal this past weekend I had the threshold knob set almost fully counterclockwise just to keep it comfortable low.

So yours has that buzz even fully counterclockwise, you cant turn it to silence either? Ive used a lot of machines with threshold and never seen this before.

Yes that is correct, I have the same buzz, just circuit noise, maybe more in certain headphones but alway there no matter how low the setting, It is normal to hear.
