The patent-pending CEIA THS 21 metal detector is sensitive to both magnetic and non-magnetic metals. The unit continuously tests and recalibrates to maintain maximum stability and performance. Its auto-learn system selects, displays, and stores sensitivity settings for up to 500 products, and Bluetooth connectivity eliminates the need to access the system’s interior for programming and data collection. Ethernet connection is also available.
