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.
Nokta Simplex+ Waterproof Metal Detector
The Nokta Simplex+ is the undisputed best budget metal detector. Waterproof, wireless headphone ready, and genuinely capable — all for under $300. It punches so far above its price class that it's the default recommendation for anyone starting the hobby.
