Our Verdicts
Garrett ACE 400 Metal Detector
The Garrett ACE 400 is a solid entry-level detector backed by a legendary brand. However, the non-waterproof design and AA batteries feel dated in 2026. The Nokta Simplex+ offers more features for less money — but the ACE 400 remains a fine choice if you prefer Garrett's ecosystem and USA-made quality.
Minelab Equinox 900 Multi-Frequency Metal Detector
The Minelab Equinox 900 is the multi-frequency workhorse that does everything well. It bridges the gap between mid-range and premium, offering Minelab's Multi-IQ technology at a more accessible price. The best all-around detector for serious hobbyists who want one machine to do it all.
