Metal detectors for searching metals in the ground

AI Thread Summary
Metal detectors function by using electromagnetic fields to detect metal objects buried in the ground. Frequencies around 8 kHz are commonly used in metal detectors, and there are no significant health risks associated with this frequency; the primary concerns are related to environmental hazards, such as being unaware of surroundings while searching. Key characteristics of a metal detector include sensitivity, discrimination capabilities, and depth detection, which determine its effectiveness in locating different types of metals.

Metal detectors for searching metals in the ground

How they work in one sentence explanation?

and second,
I've seen some frequency of about 8 kHz mentioned,could that be any possible health risk?

Please discuss, thanks.

Welcome to the PF.

You can find that info with just a little searching via Google or other similar websites. Here is a basic introduction with other links:

Let us know if you have any specific technical questions after you read the introductory material.
 
The only health risk is that you can get run over by cars while not paying attention to where you are walking.

I'm totally serious.

That and a bad sunburn on the back of your neck.
 
admin Borek you can easily delete this whole thread, no problem

i'd like to ask also what would be the most important characteristic/function of a metal detector?

Why do I have a feeling you are trolling?
 
Just ONCE, I wanted to see a post titled Status Update that was not a blatant, annoying spam post by a new member. So here it is. Today was a good day here in Northern Wisconsin. Fall colors are here, no mosquitos, no deer flies, and mild temperature, so my morning run was unusually nice. Only two meetings today, and both went well. The deer that was road killed just down the road two weeks ago is now fully decomposed, so no more smell. Somebody has a spike buck skull for their...
