shouldn't affect it any. The metal would be detected anyway. Temp. don't matter. Some metal detectors coils are made water-proof, these type you could use in 1 or 2 feet of water. Of course you might have trouble digging in that frozen ground, only to find a bottle cap or a nail, but then could be a old coin too. Ya never know. I like the beach where its easier to dig in the sand.

Kellyco Metal Detectors was created in 1955.
Metal detectors use one of three technologies. Either very low frequency, pulse induction, and Beat-free oscillation. Metal detectors work by creating an electromagnetic feild. This is done by running current through a coil at the head of the metal detector (the part you point at the ground). When there is metal, the changes in the magnetic feild are picked up by a second receiver coil.
There are many great stores that sell quality white metal detectors. These include Regton, OKM Metal Detectors, Kelly Co Detectors, as well as retailers on the Amazon website.
they detect metal
Minelab Metal Detectors currently makes their modern metal detectors rechargeable which is a lot better for the environment. The ones that take batteries die easier anyways.
The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground. The single-coil detector illustrated below is a simplified version of one used in a real metal detector. Muhammad Abubkr Saeed
Depends on the size of the metal detectors, and the size of the metal under the surface of the earth. The bigger the metal detector, the bigger the piece of metal, the deeper down it will detect.
The side effect of metal detectors is that it prevents the use of weapons and it also prevents violent crimes. The side effect of metal detectors is that it prevents the use of weapons and it also prevents violent crimes.

Click on the link below for the answer. Common metal detectors work by sending out a radiofrequency energy signal. This frequency will change slightly when the 'antenna' is in close proximity of various metals. Many metals will absorb this energy. The detector notices this absorption and can these days indicate what metal it is and even the distance to the metal. Some metals also reflect this energy signal and when a reflection is picked up, this can also be used to indicate type and size of metal object. High tech detectors use a combination of many methods of which increases its accuracy drastically.
Minelab metal detectors can be purchased from your local metal detector shop or metal detector specializing department store or through online shopping destinations such as Overstock or Amazon.
