Carl Moreland VLF Detector schematic

	We have the PCB for it too.

Thanks for the schematic Homie. I think I saw it in the download section too. It looks similar to the Bandido II Umax, but when you examine it closer, you can see there are a lot of changes.  I wonder why they had so many different frequencies?

A bad day at gold prospecting or metal detecting is better than a good day at work.

	Higher Freqs  detect smaller gold.

Does that effect depth of detection any without a change in coil size?

	A bit.    Higher Freqs are effected more buy the soil Mineralization.

Makes sense.  Seems that like there are tradeoffs for everything. Bigger coil more depth but less sensitive to smaller items. Higher frequency more sensitive to small gold but less depth penetration. Just like the government. Higher taxes to pay for things but causes job losses. Budget cutting reduces taxes, but eliminates some social services.
