Most machines are operated using microchips. This can be seen when opening the hood of the car and looking at the control box, the remote control of the television and the interior of the microwave oven.
These little things can be programmed to do whatever the person wants in a matter of seconds, which is something everyone needs living the digital age.
Metal detectors also operate using the same concept. Though this machine has been around for quite some time, advances through the years has made it much better than it was before allowing the person to use it to even detect the smallest metallic object in any terrain.
The kind of chip commonly used by the metal detector is known as the 7400 series logic. These are the tiny pins located in each card that becomes the controls of the machine. Manufactures have to be test this out so that only those who pass quality control will end up in the display shelves and into the hands of the customer.
The control box is powered by one or two 9 volt alkaline batteries. When it is activated, the person can already adjust the settings and start searching for objects buried underneath.
Before using the metal detector, it is always best to study the model and be familiar with how to use it. The individual should let it warm up for 30 minutes and then practice using it.
Lately, there have been some improvements with these devices. A better chip known as the 18 pin IC allows the individual to home in on an object up to more than a few inches away from it.
While its true that treasure hunters don’t pay that much attention to this and are only concerned with how well the detector performs, this is something worth knowing should any problem happen. The person will be able to understand what the technician is talking about to know which part will be replaced.
Those who are familiar with electronics can even make one in the garage by getting some of those chips from a radio shack or the junk yard and use it to assemble a metal detector to be able to search for the same thing.
The metal detectors of the past are nothing compared to what is available now in the market. What used to be bulky is now lightweight and handheld enabling even a child to play with it.
