Re: Dig all signals
What's your advice?
The range is not a quirk with the 250 - Just about any detector, pull tabs, foil & gold congregate in the same area of the spectrum.
You have to keep in mind, what the detector tells you is only an electronic best guess, and its up to you top make the decision to dig or not to dig.
Don't know how long you have been using it, but any machine you will learn more of what its trying to tell you.
Just about any ring will have a very sharp ding and focused pinpoint, while foil and other odd metal junk usually do not. The difference is almost imperceptible for the layman - But when you find enough gold/silver rings, pulltabs, foil, nickels ect, you will learn the slight differences in the tone of the ding and the sharpness of the pinpoint.
Which is still not fool proof, you never truly know until you dig it up.
To specifically answer your question, I'd say no, don't dig all signals, all the time.
If you are at, say, an old lot which once had a house, and there is not much trash or clad, and you find some old coins from the start, then yes, dig everything.
I found exactly such a lot, and have pulled 100's of keeper coins and relics from it. I am still hitting it, but the easy finds have already been found, now I am searching at the extreme range of my machine - Which means very slow, overlapping sweeps at max sensitivity.
At 6 inches +, a coin sized object will barely be readable for the 250, so you are actually looking for any signal with a pinpoint.
Now, if you are at a picnic grounds or something, where there is bound to be lots of trash, you'd drive yourself nuts digging everything.
I tend to just walk away from those places, even though I know that with patience, I will likely score.
Theres a park in the Detroit area not far away from me, actually more than 1, that are 100 + year old parks - And since its an inner city urban area, not much detecting has gone on there. You already know they must be loaded ,,, So what am I waiting for ? Theres been so many winos, picknics, crackheads at these places over the decades, that they are just bursting with trash. I have tried a couple times, but do not have the patience for that, so I walked away looking for easier pickings.
If I ever go back, and I should, I think I will notch out everything but quarters and dimes, and only dig signals under 3 inches.
If I have luck with that, I'll expand to include pennies - Which bottle caps often imitate, as well as nickels.
But as far as finding a long lost gold ring there, forget about it.
Tell ya the truth, you'd have much better odds finding gold rings at beaches and wood chip playgrounds than in the ground.
I've found dozens of gold/silver rings with the 250, I have yet to dig one up from the ground.
When I field hunt, my object is old coins & relics, so I hunt in coin mode - If I happen to luck into a gold ring, great but I don't expect it.
At beaches & tot lots, I do expect it - And often am not disappointed.
So in short, you have a set of tools and options for various situations, you'll have to learn to adjust them as circumstances dictate, to increase your odds at finding goodies, wherever you may be.
One thing is certain - The more you try, and the greater variety of locations you try at, the better your success will be.
Like most anything else, you'll only get back what you put into it.
If the targets are real shallow, raising the coil higher than nowmal will narrow the search "spot" and help in isolating the goodie.
