Nope, no advantages over other detectors, in fact, some people get the idea that they can tell the difference and not dig some of those low tones. Big Mistake! Dig them all......at the beach anyway. Gold rings and other valuable jewelry can come up with numbers and sounds exactly like tab and nickel numbers. Now if you're in an old, trashy area, with tons of tabs, and you only want the nickels, you can narrow down the range, but, dig a few good and bad targets to see what their relative readings are. Each piece of ground can alter the reading depending on mineralization, moisture, depth, Etc.
In a 100+ year old urban park, that can be a Herculean task, but, if you want to find gold in that area, that's what you're going to have to do. Personally, I'd rather look for gold at a swimming beach and discriminate out the "junk" targets at a park. Just not worth the effort involved for the possibility of gold vs. the time involved. If I had no place else to hunt, that would be a different story. Then I would probably grid the whole place.You generally can tell the difference between a pull tab and a nickel, but I also believe you should dig all low tones anyway to make sure you aren't missing any gold...
I didn't say I would try to do it all in one day!
In a park that has produced old coins, I'd start with the high conductors for silver and copper. Then add the nickel sounds, then zinc sounds, then all the other non-ferrous. If it was my only decent detecting site, I'd do this over a long period of time, letting the plugs recover before cutting next to them.

And he spelled aluminum wrong.....but how some people pronounce it!
