Garrett THD Instructional Video
The THD is the most rugged, compact metal detector on the market. With a highly-sensitive 360° detection area and a silent vibrating alarm indicator, the THD is the perfect metal detector for all law enforcement operations (including knife wanding programs). It is also particularly effective for use in schools, bars and clubs, and for corporate security.
