I thought I would share this with my fellow detectors. I have always wanted a way to cherry pick gold through all the pull tabs. I woke up during the night several days ago and had an idea. I put a headphone splitter in my phone jack and connected a chromatic to tuner the the quattro. Running the quattro in the conductive mode I found that 90% of pull tabs will sound at the c or d note. All of the gold I have tested has sounded A,E,F,or G note. Maybe some of you have good enough hearing to tell the difference between a pull tab and gold but my hearing is not that good. Also I don't come across gold often enough to remember the sound. I have used this setup in a test garden letting my son try to trick me and the only thing that has fooled me is the tail off of a beaver tail tab. I am excited and can't wait to try it in the park and at the beach. I know this is not 100% but it will greatly improve my odds. Does anyone know if someone has tried this before? The whole setup cost about $30.
	
		
			
		
		
	
				
			
						
					
. At the time back in 2002, when I first read that post, I tried a cheap tuner with an analogue meter needle and it was of NO benefit to me. I guess we needed to wait for a nice LCD version of a tuner like the Sabine or newer less costly and   more accurate technology that gives out a read out value. I just might try it again now that the newer technology is available, though I think I have the EXP XS and EXP 2 down pat and able to cherry pick gold form pulltabs MAYBE . Friend of mine with the Quattro is keen to try this and we will soon. Thanks for sharing your info and reminding some of us.
 Out of curiosity I've just put one of these guitar tuners on order so as I can try it out on the Explorer XS and 2, as well.
