The Different Types of Metal Detectors
Some metal detectors have different types of features and performance. Nowadays, we have different types of metal detectors available. There are metal detectors that can be used specifically for gold. There are also Metal detectors that are waterproof and can be used underwater. There are portable metal detectors, a hand held type of metal detector and a walk through metal detectors that are usually seen in different public areas. We also have an all-purpose type of metal detector and this has been very popular lately.
Here is a good definition: http://dictionary.reference.com/browse/metal%20detector. There are some metal detectors that would sometimes generate a signal even without any metal due to some food present. This is call the product effect and this happens because of the content of the food. Factors may include acidity, fat, moisture, salinity and temperature. Some things that will also affect the sensitivity of the metal detector is the product effect, size and type of metal contaminants. The opening size of the metal detector is also another factor that will affect the sensitivity of the metal detector.
Make sure to warm up your best metal detectors for at least thirty minutes after switching the power on. This should be done to be able to get accurate detections of metal. Also, burned and rustic metals may be detected but this will depend upon your metal detector's sensitivity and based on its shape and orientation to contaminants but it will be harder to detect minute particles.
Do not forget to take precaution in cleaning your metal detectors. This is to make sure that you would be able to maintain the equipment in its good shape and performance. First, clean your metal detector in a hot water lower than 40 degrees centigrade. Any dirt and unnecessary particles left in the detector head should be cleaned frequently. For this purpose you can also use detergent and a soft bristled plastic brush.
Metal detectors are usually used for security. Commonly we can find this in public areas, hotels, airports and government buildings. The best metal detectors for beginners with high target selection, a low false alarm rate and continuous detection are the best rated walk through metal detectors. Some are highly sensitive but easy to maintain with a very easy and user friendly mode of operation. The handheld type of metal detectors which are normally used in malls or schools are also very lightweight with no need of any primary check-up. It is also one of the best rated metal detectors due to its sensitivity. It is radiation free and will cost you less than other metal detectors.
