Editing Metal detector (section)

===Refinements===
Modern top models are fully computerized, using integrated circuit technology to allow the user to set sensitivity, discrimination, track speed, threshold volume, notch filters, etc., and hold these parameters in memory for future use. Compared to just a decade ago, detectors are lighter, deeper-seeking, use less battery power, and discriminate better.

State-of-the-art metal detectors have further incorporated extensive wireless technologies for the earphones, connect to [[Wi-Fi]] networks and [[Bluetooth]] devices.  Some also utilize built in [[GPS]] locator technology to keep track of searching location and the location of items found.  Some connect to [[smartphone]] applications to further extend functionality.
