| The THD quickly and effectively targets all ferrous non-ferrous and stainless steel weapons contraband and other metallic objects. Its unique 360-degree 3.5-inch detection area allows unrestricted scanning angles for fast and accurate hands-free body searches. No tools are required for replacing the 9V battery (included). Three LED function lights are included on the THD: green indicates the unit is on amber indicates the THD's battery is low and red indicates metal detection. |
