Sales and Service of Geophysical Instruments

our role

GISCO - Geophysical Instruments & Supply Company was started by Al Danish in April 1952 in Denver, Colorado.

During the uranium boom Danish marketed radiation detection instruments and field supplies to geologists and general prospectors.  Regrettably, Al Danish passed away in 1996 and GISCO was sold to its current owner and President, Nicholas Jermihov.  Jermihov moved GISCO to Minneapolis, Minnesota USA, where the company is currently located.
