Todays outing

[Tseeker]

Was able to get in about 1 1/2 hours of hunting after getting home from work today. Went back to the vacant lot which had been an old house site and is now owned by the city.
Found mostly junk and one mem cent. Still trying to learn to trust the machine. It was responding to a lot of small foil and screw caps even though I had the disc set up past tab and sens below 5. I still suspect that it is responding to roots also. I also get a wavering tone in threshold. could this be due to low batteries or mineralization or something else?
Still hardly touched this site since I am going slow.

Good. That's how you should approach it.

That's normal on vacant lots. They take mucho persistence.

Hitting screwcaps past pulltab DISC? Yes indeed. They are large, round pieces of metal. Your detector doesn't know they're worthless srewcaps... it likes them.
The foil? Dunno about that one. I'd have to see whats going on. Depends on what you call "pulltab range" and what you think is small foil.
The wavering in threshold is normal when it is set just at audible range. It could also be due to EMF interference, not uncommon in urban settings. Turn it up a tad bit, just until it gets stronger. The benefit is you will hit sharper on marginal targets.

The myth of roots absorbing metallic elements and setting off a detector is a popular one. I don't know if it has ever been irrefutably proven, but it persists. I wouldn't bet on it. More likely, there is a metal object in close proximity. I found some coins just the other day, dead under a root.

Hi Tseeker !

Re the wavering tone in threshold, I recently bought a Tesoro Bandido II uMax, used of course, and am still reading the manual over and over and learning how the machine functions, target tones, etc.. I noticed that when I set the threshold to the lowest audible level, the tone sounds bubbly to me. I called Tesoro and got Vince Gifford and he said (I'm paraphrasing) it is normal for the threshold tone to be somewhat broken, unsteady, not smooth, etc. at the lowest audible level. I find that the tone will smooth out and become steady if I just increase the threshold setting a little. On my machine that would mean turning the threshold knob clockwise. This may not be applicable in your case, but I just thought it might help to share my experience.

There is a row of ornamental plums at a local school yard that I took the Cibola to in the spring and I would have sworn the there were metal spikes in the ground all around all of the tree trunks in that row. Later in the summer they were all quite. Same thing the year before along the same row. The Cibola at the salt water beach sounds off when swung across the wet and dry sand line. I'm thinking some reaction to mineralization or change in mineral content across a swing and not a reaction to metal under these specific conditions. But this time of year with little to no sap flowing, I'd think if it sounds off, you have found some metal.

I have a Bandido II U max and the threshold gives the same wavering tone that both of you ( Todd, Tseeker) reported. Just thought I'd throw in my 2 cents! Jonny

Jonny..........I assume you mean "wavering tone" is only happening when you have threshold at or near the lowest audio setting.....correct ?

[Jonny]

Right, only when the threshold is at or near its lowest.

My threshold sound actually starts past midpoint (about 1 o'clock) below that it is silent even with the volume on my headphones turned all the way up. It has always been that way since I got the machine. Is that normal?
