The ACE 400 includes a higher, 10 kHz frequency to provide better sensitivity to low and medium conductivity targets, such as gold and lead. The detector’s Frequency Adjust feature allows users to easily toggle between slight frequency shifts to help eliminate interference from other detectors or power sources. The ACE 400 ships with an 8.5×11 DD-configuration PROformance searchcoil that has proven to be very popular with the company’s previous ACE 350 and EuroACE detectors. The ACE 400 includes five discrimination modes, electronic pinpointing, sensitivity adjustment, and High-Resolution Iron Discrimination. The ACE 400 will ship with three accessories. A 8.5×11″ DD searchcoil cover; volume-control ClearSound Easy Stow headphones; and a new ACE Environmental Cover-up to protect the control box from rain, dust, and mud. Plus a Bonus Garrett daypack.
