ANyone use the F4 for prospecting?

[robert roy]

Reading an ad for the F4 it listed its capabilities as a prospecting machine. I'm skeptical.
Has anyone any info on this?

Hi Robert,

I have plans to do some prospecting with my F4. I have some sample gold pieces and at turn-on sensitivity level it picks up a 0.15 gram at about an inch or so. A smaller piece of 0.1 gram doesn't register.

SO...perhaps not the the best choice for prospecting but it works. I've got panning experience and I recognize and have had a fair amount of success finding at least "some" gold without the detector.

In my beach and dirt hunting I've found a lot of different things from lead to silver. I average about one ring a week and a bunch of other "things" working about 5 days a week one hour a day. It found me my first (and only) silver coin, '52 Roosevelt and about 3 wheats. I don't really hunt old sites enough but I am doing the research to improve that.

HH, Joe

Thanks. I suspected that this was probably the case. I know its possible to pick up a nugget or two with the Ace but
small stuff is out.
Regards
Robert

Hi Robert Are you using the 4" or 8" coil?

The 4" BH Gold Nugget coil is very sensitive on small gold .

Thanks for that information.

Bumping up an old topic, but had a topic related question.

What mode would you guys use for gold prospecting, the all metal discrimination or straight all metal so you could ground balance ?
