Metal Detecting

I''m new to MD and the Deus. I am successfully missing all of the iron with the GM Power mode but keep on digging countless foil, ring pulls and cans. Can I discriminate against them at the same time as the iron using the notch function?

Detectors find items based on their position on the conductivity scale and amount of discrimination used....
Unfortunately ring pulls, silver foil etc have the same/similar conductivity signature as Hammered coins.
Rejecting ring pulls would also reject a majority of hammered coins.....

Bruce aka Black Adder says it as it is discriminate foil at your own peril however as a Deus owner since they where released believe me when I tell you after a very short period of time your ears should tell you the difference between cans and coins however I nam still trying to find a way to differentiate between the sound of foil and hammies I don't think I will ever get that one

Keep it low keep it slow

You can notch out most ring pulls by setting the notch to between about 61-71. But as has been said, that will cause you to miss some good finds. I'd only consider using that type of notching on a trashy site with mostly modern finds( e.g. a beach), really.

I sometimes set a notch to knock out ring pulls and bottle tops while leaving the Deus able to detect 20p/50p/£1/£2. You can do this by leaving 'open' numbers 67-89. Test it out on the ground conditions you are in for the exact numbers needed.

I rarely dig under 40 on the beach but I've had jewellery come through in the 50s.

The man who invented the ring pull has a lot to answer for .

PS I've found that the older style ring pulls tend to give a higher reading than the newer style ones.

if we could sell ring pulls and bottle tops we could retire early
