REVIEW: Meter for low-frequency magnetic fields, range 30hz > 300hz, good to measuring electrical networks or power lines, not good for radio networks (RF) like phones, wifi, radar, routers, etc..
Battery powered, work time 10 hours.
Good overall quality, accurate and precise measurements.
It has an external probe that I don’t understand, maybe for narrow place?… I do not know!
MY PERSONAL OPINION: This a good quality meter, price is not low for a magnetic detector but you pay the quality . By the shape seems a toy but is not!
