I've been out of detecting for a few years due to medical problems.  I finally can get out and detect and am interested in getting a different search coil for my Spectra.  Never cared for the D2 coil and mainly use the 6x10 and 5.3.  I need a coil to replace the D2 and don't want a concentric.  Anyone have suggestions on a good coil?  Before I had medical problems I had thought about one of the SEF coils like a 10x12 but thought I'd check and see if there wasn't another option.  Thanks for any help.
	
		
			
		
		
	
				
			 
						
					 I was going to do the upgrade and have the coil checked several years ago but kind of forgot about it when I had medical problems.  My machine is long out of warranty, the sticker in the control box says 2009.
