Again, I say watch the Meyl videos and read some of his website. maybe you will learn something. Study the near field. If you are using 300MHz, well the near field is not too far, maybe inches. The frequencies used in the MFD are in some cases less than 100Hz, but even at 5KHz it's a few miles. Not saying an MFD can pick up a target at that distance, but maybe if the target is a large vein.
