Speaking of super tuff, I was shocked when I started hearing about lots of guys that were having problems with the ears of their newer Minelab coils breaking. I never had that issue or even heard about that with my Sovereign's. I checked out a lot of videos on YouTube covering how to fix broken coil ears, how to reinforce coil ears so they don't break, etc. Then when I got my X-Terra Elite, I saw why lots of guys were having breaking coil ears. The ears on my X-Terra coils are so thin, maybe a 1/16th or 1/8th inch wide, but kinda wimpy looking.
I've been swinging my Minelab Sovereign Elite for the last 14 years, never had any problems with coil ears, never heard of anyone having those issues with the older Minelab's. My Sov is built like a tank; just take a look at the 8" Tornado coil pic I've attached. This coil isn't mine, just grabbed it from the net. I have a 10" Tornado but take a look at the ears on the original coils that Minelab used to make. They're REALLY thick, probably at least 1/4" wide. Don't know why Minelab would have went with such thin, wimpy coil ears, when they could have just kept the ear design they've been using with the old coils, and they probably wouldn't be having this issue.
