All I can add is my experience which is the minute I turned off the discrimination and only left on the iron mask- my luck dramatically improved. Yes you have to be willing to dig but all the good stuff we find is pretty shallow - even Heatho and the Aldi found a gold ring recently... I wonder how many you've walked over already?
Even Heatho.....lol. Look my take on the matter is I'm with you Paul Marr, the thing with the Aldi is I totally ignore the readout of what it's saying a target is and only use my ears, Gold will be solid mid tones mostly...... whether 9k or 18k, same as $1 and $2 coins, the ring I got the other day though jumped up to one or 2 high tones from a majority of mid tone (high conductor tone) due to the copper/gold alloy. All pennies are usually a high tone as is sterling silver. Old ringpulls give the same solid mid tone as goldie coins usually do and I dig a hell of a lot of old ringpulls, hundreds each week.
Modern pulltabs jump from mid to low to high. With the Aldi the trick is to wave it over the target at least 10 times quickly from different directions, if the tone doesn't drift to a low tone it is worth digging, if it drifts from mid to high it's still worth digging, if it's a solid tone with no drift from mid tone then it is nearly always a 1 or 2 dollar an old ringpull, gold ring or medium conductivity target.
I'm even starting to recognise old ringpulls due to the detector being less reactive over them, 1 or 2 dollar coins and rings make the detector react very quickly, it's a tad slower over ringpulls but you still can't be sure, modern pulltabs are pretty easy to pick and ignore mostly.
The best thing is it totally ignores beer bottle tops, you'll very rarely find one in my junk pile. It's mainly ringpulls, aluminium screw caps and other aluminium junk.
I've found 3 nice gold rings so far with the Aldi, one had diamonds....., I like the 9k ring I found the other week, fits perfectly lol, though I almost dismissed it as a modern pulltab, just there was no low tone so I dug it thankfully. The only reason I haven't upgraded yet is because I know I'll be digging even more junk than I already do. Within a month though I'd say I'll have a 3030.
My back and knees hurt too, last time gold detecting they were 4 x 10 hour sessions and my feet swelled up but gold always relieves the pain......
