Is this unusual or the norm........

[Ivan]

While using the DeLeon with the 5.75 concentric coil I noticed something strange. I was testing a 14K and a 18K fine chain in the all metal mode and they wouldn't make a peep........they had to actually touch the coil to give some sort of broken response. OK no big deal......after all this is not the Compadre, but then something weird! I put the Deleon into the disc mode and turned the dial to it's lowest point and........even at 1 1/2 to 2 inches ...the chains gave a fairly good signal!!! Does the disc mode set at the lowest, go below the all metal range? Is this the norm or is it particular to my specific detector and coil? I'd appreciate a bit of feed back.... see if your DeLeon does this........could be useful info when hunting for gold jewelry. Thanks.... for feedback and useful observations..........were all in this together.

I typed a 5,000+ word post this morning and lost it so let me think about trying to posting another response. I have a ton of info that I've gathered from The Deleon,I'm sure a lot of it is common knowledge, may already be posted out there some where. To simply answer your question.Leave the disc in disc mode set to the minimum disc setting.,threshold set 1/8 " into the beginning of the red band above the dial.Sensitivity set between 5-8, I prefer closer to the 5 side, especially when hunting for gold items.You will see the ^^^^ symbols on each side of the numersitic value.Usually an indication to lift the coil but in this case, there is no gold tab, so it's not going to help identify the target.It will register in pull tab section. Not being able to identify it on display, smaller gold chains is nothing more than a snap sound depending on depth, sounds much like trash, but watch the numbers, they'll bounce in a numeralistic pattern, unlike true trash bits.The Deleon is an different animal, learn to leave disc knob alone and thumb the threshold/sensitivity. Bigger gold rings will sustain the faint tone,much like the faint tone that you get when you find a silver dime deep but the tone is sustained 4-5 times longer. It is really a distinct sound much like the deep silver sound but with a sustained urgency, same deal the numeristic value will bounce but be identical in the numbers that it bounces back and forth on.You will see ^^^ symbols around the numbers.The compadre really is better suited for gold stuff but the Deleon can find its share.The only time I run sensitivity up on max is when I've picked the area previously off at a lower setting or I am in fields where there is fewer targets in the mix.The sensitivity is like searching through fog with the Deleon's display.With the sensitivity turned up high, it's like running through fog with high beams on, not very helpful in most situations, run through the fog on low beams= cut the sensitivity back .You will get a clearer picture of what's there.I hope it helps.

That's just about the best advise you can give to Tesoro people. I've found that the only places where I can run sensitivity way up is in very low mineralization, like deep compost or pine needles. Where mineralization is high, the ground seems to bounce back too much of the transmitted signal, so you're better off turning sensitivity down lower. I see that on shallow coins, especially larger ones like quarters, target response will be more clear at lower sensitivity. Turned up, the quarter sounds less like a good target.

While the responses are useful .....they are side tracked from the original question. Does the lowest setting in the disc mode...........go lower than the all metal mode. A fine gold chain and a test....as I've laid out are the only way to find out .....and get a factual answer. Monte....are you game for this challenge!

A traditional Tesoro paradigm pattern ? You have a 8 AA battery ,analog to digital display system that is tuned to a 9x8 coil. Is it going to yeild the same results as setting a traditional single 9 volt analog system with the 5.75" coil ?

With absolute certainty , the disc knob does go lower than the AM mode setting. In saying that, the Deleon's discrimination mode does not work the same as other Tesoro machines. Is it because of the analog to digital system configuration ? The all metal mode does not work the same on the Deleon as it does on other Tesoro machines. To compare further, I wish it had the old sabre II no motion all metal / disc mode toggle system but the Deleon doesn't remotely try to mimic the sabre while having an all metal/disc mode toggle system.The Deleon is different, either you warm up to its chacteristics or you get rid of it.The Deleon is a splendid coin hunter,very underrated, to the point that it's Tesoro's best kept secret..........

never owned a Deleon so cant say but the 2 current Tesoro's with 180 disc are Tejon and Compadre , so you would think they would go further in to the iron range in disc mode than the Deleon does.

gold is not iron so I don't see why digging iron will find gold fine or other wise sure get right on the edge or maybe some masking happening but other than that for me until I know otherwise iron is iron.

This makes me wonder if the signals given in disc mode are in reality from the quick reset of Tesoro- the detector giving a tone from actually resetting going over a partial reject of the chain-especially with the small coil. The small coil would do this on my Silver umax. Just a thought. The Garrett Ace has a small amount of iron reject in am mode. Could be in the design.

The all metal mode on the DeLeon is not a true all metal mode. I'm not an electronics engineer, so I am not going to try to explain how this might affect signals....I don know that on some Tesoros, to pick up fine gold (eg small sleeper earrings) you do have to have the Disc. set below Iron. Larger gold, such as small rings to larger rings will come in above Iron.

You're not actually digging iron targets unless you want to but the low disc setting allows you to see everything , including very small items as was explained by Furious T.

Well some good replies for sure.......I am quite impressed with the DeLeon......think it is under rated..... a sleeper... but not in the field...light weight and quite powerful. I am hitting coins at 4 to 6 inches with a sensitivity setting of only "3" . I think I like this detector!!!
