GARRETT ACE APEX Multi Frequency Metal Detector FREQUENCY OPTIONS 5 kHz 10 kHz 15 kHz 20 kHz Multi-Salt Multi-Frequency The name of the game is Total FLEXIBILITY. Fueled by a cutting-edge, broad digital interface, Garrett's Multi-Flex technology simply offers you more Apex flexibility than can be found on any detector in its price range! To achieve excellent detection on all targets in all soils or sands, choose from powerful single frequencies to improve detection on specific targets*, or choose one of Apex's simultaneous multifrequency modes. 8 CHANNELS PER FREQUENCY For both single and multi-frequency, Apex has eight independent frequency shifts, or channels. That's 48 different frequency settings, giving Apex greater capacity to search at packed rallies alongside other detectors and to withstand electrical interference. *Note: Lower frequencies typically provide greater and more conductive targets with better detection (e.g., large silver coins).. In general, higher frequencies provide greater detection on smaller and less conductive targets (e.g., hammered silver coins, gold nuggets).
