From what I have read, the Magnacast 5000 is similar to the other MFDs that are manufactured by Vernell Electronics, and is a simple variation of the theme. It is hard for me to believe any of the Vernell equipment can work because there is not a single incidence of someone demonstrating it locating unknown treasures in front of witnesses.
But the best evidence I have that the transmitter is simply a signal generator with no power amplifier or tuning coil is the circuit diagram shown by Carl NC when he opened the VR-800 MFD (a similar MFD manufactured by Vernell). This was a predecessor to the Magnacast 5000 which also is claimed to work on the same "forward gauss" detection principle as the other MFDs that Vernell manufactures. The difference is the 5000 comes with the coil receiver instead of L rods to scan the field. See Carl's report for the VR 800 here:

Here is the VR 800 circuit. Do you think you can broadcast an RF signal if you connect Vout to a rod stuck in the ground, or to a small antenna set on the ground?
Wouldn't a real transmitter work better, even if it is only a cheap $10 pocket transmitter?
A close look at the circuit will show there is no RF power stage or tuning coils. This circuit is a simple square wave signal generator that is optimized to create a product that can switch on lights for a nameplate that says copper, gold, silver lead, tin and diamond. If you wanted a circuit that does this, can't you build the exact same circuit for less than $5?
Do you really believe the Magnacast 5000 has high tech circuitry inside and a real transmitter?
Why not open one and see what's inside?
Do you think you will find what everyone else found inside the Vernell products?
More evidence came when Dell Winders had something to say about the Vernell locator concerning his failure to win the Randi prize by locating coins hidden in the sand:

But looking at the circuit, my opinion is conditions never existed that would make any Vernell product practical for use by anyone except a rich person who wanted a plastic box with 6 leds on the front, or a child who wanted a toy to play with.
