Whites MX7 on silver?

I owned the MX Sport which is basically a waterproof MX7. It was a good detector like all Whites machines that I have used. My MX Sport hit coin signals very hard and was a deep machine. The only reason I got rid of it was that I have RA and the weight was getting to me. I am a Whites fan and think that they ID targets about as good as any. Whites also stand behind their products and their customer service is excellent. They also recently released the six shooter coil for the MX series and I think it will be a killer in trashy areas.
