THANK YOU FOR CHOOSING
GARRETT METAL DETECTORS!
Congratulations on the purchase of your new Garrett AT
Pro™ 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 AT Pro includes Garrett's exclusive Target ID technology and patented discrimination features. Two indicator scales allow you to see the detector’s discrimination setting (Lower
Scale) as well as the analysis of each target (Upper Scale).
In addition, a Digital Target ID scale provides a more specific target value. The AT Pro also features High Resolution Iron
Discrimination (40 points) for separating desirable targets from iron junk in cluttered areas, several advanced audio features and a standard 8.5" x 11" elliptical Double-D searchcoil engineered for optimum performance in more challenging mineralized soils. In addition, the AT Pro can be operated in a very user-friendly Standard (STD) Mode or in a more advanced PRO Mode for experienced hunters.
Backed by more than 45 years of extensive research and development, your Garrett AT Pro 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 detecting environments. The AT Pro's advanced features are designed for the expert treasure hunter but its Standard Mode can be easily operated by the beginner. In order to take full advantage of the special features and functions of the AT Pro, you are urged to carefully read this instruction manual in its entirety.
