Fisher M-Scope Gold Bug 2 Operating Manual Download Page 3

    The Fisher

®

 Gold Bug™, the predecessor to the Gold Bug™-2, was 

designed and engineered by Fisher

®

 engineers from the ground up for 

the sole purpose of finding deep, small, and large gold nuggets in highly 
mineralized soil. Almost overnight, the Gold Bug™ became the standard 
against which all other gold-hunting detectors were compared. 

    The next generation Gold Bug™, the Gold Bug™-2, is not meant to 
be a replacement for the original Gold Bug™. Your Gold Bug™-2 offers 
many of the successful features of the Gold Bug™ as well as some new 
features, making it a distinctly different detector, but still designed for the 
sole purpose of finding gold nuggets. 

    The first and foremost of these new features is the operating frequency 
of  the  Gold  Bug™-2  (71  kHz). This  ultra-high  operating  frequency  is 
extremely sensitive to small gold nuggets, and it also offers a side benefit. 
Because the Gold Bug™-2 operates at a different frequency, it can be 
operated near an original Gold Bug™ without interference. 

    Also, a new mineralization switch on the Gold Bug™-2 can be set for 
high, normal and low mineralization ground conditions. When set for 
high mineralization, this new circuitry allows prospectors to hunt in areas 
previously off-limits due to high ground mineralization or numerous hot 
rocks. Although the original Gold Bug™ is known for finding small nuggets 
in highly mineralized soil, the Gold Bug™-2 will set new standards for 
both size and depth under many soil conditions. 

    Iron discrimination is another new feature. In the IRON DISC Mode, 
you can identify hot rocks and small trash items like iron nails and other 
ferrous trash before digging them. Use this mode in extremely trashy 
areas to check a target for its iron content.
