This is an open-box Garrett ACE Apex with the 6" x 11" DD Viper coil, the Multi-Flex multi-frequency detector Garrett built for coin, jewelry and relic hunters who want simultaneous multi-frequency and built-in wireless audio at an entry-level price. It is the same machine as our new Garrett ACE Apex with Viper coil, sold at a discount because the box has been opened.
Condition and warranty on this open-box unit
[Condition: e.g. "Customer return, box opened, detector powered on and tested, no cosmetic wear, all factory contents present" / "Store demo unit, light handling marks on the control box"].

Our 30-day return policy applies exactly as it does to new stock. Stock on open-box units is limited to what we have on hand; when this listing sells out it may not return. See the rest of our used and open-box metal detectors for other current deals.
Open box or new: which Apex should you buy?
If the saving covers a pinpointer or a coil cover, open box is the better buy for most people, since the detector is functionally identical and still warranted. Buy new if you are giving it as a gift and want a sealed box, or if you plan to resell it later. If you want the larger 8.5" x 11" Raider coil for open-field coverage instead of the Viper, that configuration is only available new in the Garrett ACE Apex range. Our Garrett Apex guide covers how Multi-Flex compares with the single-frequency ACE 300 and 400.
What the Apex does in the field
Multi-Flex gives you four single frequencies (5, 10, 15 and 20 kHz) plus two simultaneous multi-frequency modes, and eight channel shifts on each to move away from interference. In practice that means running multi-frequency in a park to hear coins and jewelry together, dropping to 5 kHz for deeper silver in clean ground, or stepping up to 20 kHz for small gold and thin chains. The 6" x 11" DD Viper coil is the tighter of the two Apex coils: it separates targets well in trashy sites and slips between roots and rocks, at the cost of some coverage per swing. Iron Audio and Iron Volume let you hear ferrous junk at reduced volume instead of silencing it, which is how you tell a bottle cap from a coin without digging every signal. Ground balance runs to 175 points, enough to settle the machine on wet salt sand, and the coil and lower shaft are submersible while the control box is rainproof. Built-in Z-Lynk wireless pairs with Garrett's wireless headphones and the Pro-Pointer AT Z-Lynk pinpointer so both alarms arrive in one headset.
