I had to go back to basics and reduce the noise from the detectors own switch mode power supplies, and by doing so reduced the internal noise by half.

Flouors..Led's ..switchmode chargers..phones in the room also create EMI ...IMHTO 👍

Another great video! Are the shields you added ferrite?

No, but they can be, i had to use copper and a type of mu metal.

@@DetectorMods I'm considering applying a thin coating of ferrite mixed into acrylic glue (Marine Goop) on top of masking tape, to the top and sides of the coil. VLF Minelab Manticore. I'm curious if like your copper cloth EMI mitigation filter, am I able to reduce the EMI by a meaningful amount? I appreciate a quiet detecting experience.

Did you check if the SMPS switching frequency is synchronous with the receiver timing?
@DetectorMods
@DetectorMods Год назад
It is not synchronized as the noise is continuous over the TX RX cycle

@@DetectorMods Wouldn't that only indicate that the frequency is faster? As long as those switching edges don't change in time, wouldn't they be static from the perspective of the receiver?
