We should know how metal detector works before we get to know it. Underground metal detector is also a treasure hunting detector. Gold metal detector uses electronic magnetic induction working theory. When the current goes through the metal detector coils, a magnetic field will occur. The magnetic field will occur a eddy current inside the metal. Another magnetic field occur by the eddy current and start to affect the original magnetic field and make the underground gold metal detector sound beep.

The accuracy and reliability of the deep ground search metal detector is mainly decided by the stable performance of electromagnetic launcher frequency. Usually, Pinpoint ground searching metal detector factory setting working frequency is from 80 kHz to 800 KHz. The lower working frequency the better the pulse induction metal detector works on iron. The higher the working frequency is the better the metal detector machine works on high-carbon steel. The larger the searching range the lower sensitivity the metal detector handheld is. The treasure hunting metal detector detection signal is mainly decided by metal size and conductivity.

OK, now we are clear about non ferrous metal detector working theory. It is the right for us to choose a metal detector with reasonable metal detector price for ourselves.

Pinpoint metal detector and security equipment factory is a well-known enterprise in Shenzhen. We are the leading metal detector pulse induction factory in China metal detector industry. Our clients are all over the world. All our metal detector and security equipments are certified by police security department. Other than our deep earth metal detector, our metal detector door adopts anti-fire plate. Our door frame metal detector has fire-proof, water-proof, shake-proof and light weight advantages. Our archway metal detector sensitivity, effectiveness, stability and anti-shock data are leading in walkthrough metal detector industry.

Many people compare Pinpoint metal detector with foreign metal detector sale. Foreign metal detector price is super high and people think its price is high because of high technology and quality. But actually it’s a misunderstanding. Foreign deep metal detector raw material and labor cost are much higher than domestic industrial metal detector. And plus the transportation cost and custom cost, that’s why the foreign fisher metal detector price high.
