THANK YOU FOR CHOOSING
GARRETT METAL DETECTORS!
Congratulations on the purchase of your new Garrett
ACE 350™metal detector. This enhanced metal detector
has been specifically designed for use in more challenging
environments such as mineralized grounds and iron-cluttered
relic and coin hunting areas.
The ACE 350 includes Garrett's exclusive Target ID
technology and patented discrimination features. This
technology features two indicator scales that allow you to see
the detector’s discrimination setting (Lower Scale) as well as
the analysis of each detected target (Upper Scale). The ACE
350 also features Enhanced Iron Resolution™(additional
resolution for separating desirable targets from iron junk in
cluttered areas) and a standard 8.5" x 11" elliptical Double-D
searchcoil engineered for optimum performance in more
challenging mineralized soils.
Backed by more than 45 years of extensive research
and development, your Garrett ACE 350 metal detector is
the most advanced of its kind in the industry. Whether you
are experienced or a beginner, this machine is well suited
for a wide variety of your detecting environments. With One-
Touch™operation, the ACE 350 powers on with the touch
of a single button, adjusts easily for ground minerals and is
immediately ready to begin searching.
In order to take full advantage of the special features and
functions of the ACE 350, you are urged to carefully read this
instruction manual in its entirety.
