hi everyone,this is my first posting and i am from adelaide australia.i have a minelab safari,before that i owned a quattro.both machines are great but i think the extra speed of the safari is a help.recently i found a 925 silver ring an ear-ring plus the usual suspects of coins,buttons,plus the dreaded can tabs and caps.i love hitting the silver 38 ish id and sharp high tones make life easier.i still can get a bit unsure with lower carat gold rings as they can have very similar id numbers and tones to can tabs.i am using relic mode, low trash and sensitivity at 15.i think it can be a bit risky discriminating some of the low numbers say at 15 to 17 because my wife has a watch which falls right on 16.i usually beach hunt and any advice on this would be great.its fun to read everyones experiences and advise,thanks from peter27.
