Something Strange About My F-70

[limegoldconvertible68]

I dug my first barber dime yesterday. It ID'ed in the low 20's but the depth reading was 10" so I dug it. When I got home I started experimenting on the surface of the ground with different metal objects in proximity to coins. My F-70 failed one test that baffles me. I layed out a zinc penny, a nickle, a dime and a quarter in that order. They were in a straight line with roughly 1 1/2" between them and a normal swing speed the detector would not give a solid signal. It gave a choppy sound and ID'ed as foil. I was shocked! My trusty ole 1265x reads it as one good signal. Is this normal for a stock F-70? How about some of you who have added the 11" DD, does the F70 read this setup any better?

Perhaps its reading several coins at once . Mixing the id up. I hear faster machines have trouble iding when multiple targets are present. Hmmm

And lets face it, what kind of real world test is that?! Take one of those coins and place it within the same distance of a rusty nail or pulltab... then get back to us.
