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 8.511 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 FREE accessories to complement the new release: an 8.5 x 11 in. 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.

• Electronic Pinpointing: precisely locates targets and speeds recovery
• Notch Discrimination: Modify discrimination patterns based on what you are seeking
• Stable Camlocks
• Adjustable Frequency Eliminate or minimize interference caused by electrical sources or from other metal detectors (such as at crowded club hunts, rallies).Frequency 10 kHz
• 8.5 x 11 in. DD PROformance search coil
• Includes: Easy Stow headphones, ACE cover-up, coil cover
• Graphic Target Analyzing Simultaneously shows a treasure target's conductivity and the detector's discrimination pattern.
• Increased resolution (more pixels) allows more precise control of how much iron discrimination to apply. Very useful in areas where desired treasure targets are being masked by iron trash.
• Electronic Pinpointing This non-motion All-Metal Mode function is used to precisely locate a detected target's position.
• Digital Target ID Numeric identification scale from 0 to 99. Identifies a target metal's conductivity.
