Help with serious gold prospecting

[Congogold]

I am a novice who is fortunate to be working in Congo RDC. I buy and export raw gold and have the opportunity to find my own.
Most people using the detectors seem to be looking for coins and treasures. I on the other hand am in rich gold country. I have bought the whites GMT, OKM Rover Deluxe & garrett Infinium to use here in Congo for serious gold prospecting.
Currently I use the Rover for imaging and whites for confirming content already dug out soil> I have recently visited a producing gold mine with the intention of using the Deluxe images to help me better identify gold when I see it in the images. However, so far all images are very similar> In the manual it shows gold as 'red'. My scans show orange in almost every scan anywhere I scan- obviously I can't be seeing gold everywhere and i can't dig everywhere.
I have reads the manual many times and still can't tell the difference between gold and heavy mineralization or ferrous metals! It is driving me crazy...
I am in prime gold country- i buy plenty from artisanal miners who find their gold the old way- I can't seem to get results with the technology at all.
My question is- do i need a specialized detector for this type of prospecting i.e. veins, placer, alluvial gold? or am i not interpreting the scans correctly.
I really need help badly.
Thanks.

I don't know anything about the Rover other than what I see in the advertisement, but it appears to be a PI detector with data logging ability. If so, it is not going to be able to discern gold from anything else. Furthermore, what you get out of the data logger will be more of a relative output than any kind of absolute result, so you really need to scan the entire area, plot the results, and then have a way to determine what the data is telling you. This probably means practicing with the unit in areas where you already know what is going on -- sounds like that is what you are trying to do.

Of course, it may be that the Rover just isn't useful for this kind of work, I don't know. From everything I see, people who are finding gold on a small scale are doing it the old-fashioned way... metal detectors, pan/sluice/dredge, and maybe a bulldozer. I have yet to see any magic gold locator that actually works.

Thanks Carl- I have to say- I agree, one has to improvise. It should be a mixture of technology, geology, old fashioned hard graft and some luck. No machine is going to lead me straight to gold.
