SMW metal detector using Tianxun TX-850 coil

In this video, we demonstrate the assembly and practical testing of the SMW (Silver Metal Wave) metal detector circuit paired with the Tianxun TX-850 coil. Check out the audio response, sensitivity for identifying metals (coins, rings, and small objects), and the control panel adjustments. An excellent choice for DIY VLF/SMW metal detector projects, offering great stability! 📌 Topics covered in the video: Introduction to the SMW circuit and TX-850 coil Detection test using a ring and coins Control and potentiometer adjustments Response and sensitivity tests 🔔 Subscribe to the channel for more tests, electronic circuit schematics, and DIY metal detector projects! #homemademetaldetector #SMWdetector #TianxunTX-850 #TX-850coil #metaldetectorcircuit #SMWdetectorwithTX-850coil #DIYmetaldetector #metaldetectortest #metaldetectingBrazil #metaldetecting #howtomakeametaldetector #metaldetectorsensitivity #TX-850metaldetector #SMWmetaldetector #VLFmetaldetector #metaldetectorelectronics
