Deviation   information   is   valuable   in   mine planning    and    subsurface    mapping.    The gyroscopic    device    is    used    for    measuring deviation    through    steel    drilling    rods    or casings   and   in   open   holes   where   magnetic rocks   occur.   The   digital   solid   state   design uses     a     continuous     reading     gyroscope (modified     Goodrich,     or     WellNav),     with information   recorded   at   operator   selectable sample   intervals.   It   is   not   necessary   to   stop to   take   station   data.   Natural   Gamma   and Magnetic Azimuth   are   optional. All   software to    process    survey    data    (including    drift corrections)    is    included    in    the    Log    and Display    programs    which    is    included    with the System VI logging system.
