Gold Mountain King Cobra

I love this Metal Detector and I find a lot of good things with it! I'm looking for a 8" inch loop for one, mine the tab chipped and it's barely hanging on,  I am looking to replace it (the Loop). I know this is an oldie, but it is a goodie and I would like to fix it an continue using it. I already contacted Keith Wills in East Texas (great guy) and he only has 4" inch Loops for the King Cobra at a great price. Any help would be appreciated, or suggestions of using another brand Loop that is compatable with the King Cobra 15Khtz.
