Bayard, I bought the six inch Excelerator and had a chance to try it out today. The ground was good from the recent rain but I stayed in the shade area's anyway.
The coil seemed to hit well and very clear tone on shallow or deep targets.
One thing I noticed was the tone was different from the minelab small coil that I was using. Any change you make on these machines changes something (not complaining - just a statement of fact).
So beside the tone difference I have to slow down more, this thing is so light weight I was swinging away like I was cutting grass.
I like it so far, I can't wait to find my first silver with it......thanks for the suggestion.
