About us. . .

Hi, I'm Miner John!   I purchased Razorback Coils in late April of 2013 and have changed the company to Miner John Designs.  I've been a metal detectorist since 1990 and made a living finding gold nuggets for years with my metal detector (and the help of a few friends).  Now I'm involved in building products that will be top performers in this competitive detector arena.  With my experience in the field as well as my fabricating abilities, and with the help of a few new good friends, I plan on making products that you will appreciate using.  I am a small operation, with just me and my wife currently doing all of the work.  Everything is tested personally by me before selling it to you.  You'll notice frequent new products, and changes to existing ones, as I continue to develop the various product lines.  I am always open to feedback from my customers, and will give credit where credit is due.  I look forward to making many more new friends in this endeavor.
