F5 question

[Mr. Beard]

For those who have used the Fisher F5, I saw a tube video on the F5 and the guy was saying that his F75 sounded off the same on bottlecaps as it did on quarters. But the F5 in the 4 tone setting had the quarters in the high tone and bottlecaps the mid tone.
Is this correct???
I have experienced many quarter signals and dug a bottlecap with some detectors.
Are the F5 tones different on the quarter and the quarter range--bottlecap ??

Most times I get a mid tone on bottle caps too, but once in a while I get them at a high tone(especially beer bottle screw caps). It just depends on the composition of metal they are made from. Quarters are consistently in the high tone on my F5, @80-82 in mild ground.

Sqwaby,


I sent you a PM

Bottle caps are about as bad as pull tabs. They can still fool just about any machine.

It all depends on how deep these tabs and caps are and how long the have been in the ground. Sometimes my F5 just passes over them and sometimes it will ring high. Oh maybe someone will come up with a detector that will find gold and silver only.

I find crown type bottlecaps to almost always ID jumpier than quarters, but I dig 'em anyway. Usually they hit high tone with my F5.

Quarters for me in my moderate ground hit higher than for squaby. And silver higher than clad. 78-81 is the most common silver rosie range for me.
