The sounder works as advertised. Tuning a mag loop antenna becomes child’s play! When I had a question about how to use the sounder in conjunction with the built-in tuner on my Xiegu G90 customer service responded quickly.
Simple to use, easy to hear and gets you right on point where you want to be.
This small device makes tuning my mag loop a breeze! The audio tone allows me to tune by ear rather than sight!
