Head-To-Head Comparison
Garrett ACE 400 vs Nokta Simplex+
A quick, honest look at how the Garrett ACE 400 and the Nokta Simplex+ compare on specs, depth, price and real-world performance.
🏆 Our Top Pick
Simplex+
This is a cracking head-to-head because they’re about the same money. The Garrett ACE 400 is a dependable, easy beginner machine, but the Nokta Simplex+ packs more in at the price. It’s fully submersible to 3m, with built-in wireless audio, a rechargeable battery and manual ground balance. For a newcomer who fancies a bit of beach or river work, the Simplex+ is the better-equipped buy. The ACE 400 still wins on Garrett’s huge support community, if that’s the sort of thing that reassures you when you’re starting out.
