Jim, it might help to explain what the task is you have in mind for each detector.

 

     If I had a metal detector question I would go on line and look up kellyco  metal detectors, get their phone number and give them a call.

 

     Tell them what you want to do and they will help point you in the right direction.  Your pocket book will most likely be the deciding factor.          Ron

Thank you Ronald,
I have spent quite a bit of time on the Kellyco site.

My thoughts were this:
The Gold Bug 2 for nugget hunting in the dry washes of California and Arizona mostly and the MD 20 to basically "search" for pay layers in my prospect pits.
I was just looking for a little first hand (or even second hand ) info from some folks that may have used either one.

Thanks for the reply Ronald!
Happy Huntin'
Jim
