Mineralised site

[peter01]

Hi there
Has anybody got a suggestion about setting.? I recently got permission to detect on an old race course which closed in about 1930. It over looks the sea and is in a fabulous location. I use a Quattro, on my first outing I walked around the whole course a large area. When i put the machine in all metal it just kept giving of iron signals. If I dug a hole the pin pointer just kept buzzing, I could find no iron. It looks like the ground is heavily mineralised. The site should be full of nice finds as its never been detected on. But I seemed to get very few good signals my only find in six hours of searching was a nice 1929 florin Has anybody got any suggestion's as the best way to search this site.
Regards Peter01

My suggestion would be to start with a smaller DD coil, like a 6x8 SEF coil and discriminate iron out as well as 40 to help stop iron wrap around. If you don't think jewelry possibilities are there, I'd discriminate up to foil out as well because there more than likely will be a lot of foil there also. JMHO.

Thanks for your suggestion, I only have an 11" pro coil so the smaller coil is out at the moment. I have tyred discriminating iron out and it gets rid of most of the iron signals. But the find rate for the site seems low, I thought I would try reducing the sensitivity as i would have thought the goodies would not be to far down.

Peter, congrats on gaining permission at the track. I too, have just the 11' pro coil so try turning sensitivity down to 14 to start and switch over to factory coin or coin/jewelry programs. If still running quiet, bump it up to where the chatter starts and set sensitivity there. Should help improve depth on finding older silver. Looking forward to your pics.
