Independently researched Detector Comparison
Garrett ACE 400 vs Minelab Vanquish 440
Vanquish 440 is the better mixed-terrain beginner detector because Multi-IQ handles changing ground and wet salt more broadly. ACE 400 counters with 10 kHz response, Iron Audio and an 8.5×11-inch DD coil for inland coin and relic work.
Bottom line
Vanquish 440 for versatility; ACE 400 for Garrett audio and inland familiarity
Choose Vanquish 440 for Multi-IQ, compact storage, Custom mode and easier transition between parks and beaches. Choose ACE 400 when Iron Audio, Garrett’s 0–99 interface and the larger stock coil are preferred at a lower price. Neither control box is submersible; their waterproof coils do not change that.

Decision analysis
What actually changes the purchase
ACE 400 is a 10 kHz single-frequency detector with five modes, 0–99 Digital Target ID, Iron Audio, electronic pinpoint and an 8.5×11-inch DD coil. It is straightforward but lacks manual ground balance and modern SMF.
Vanquish 440 uses Multi-IQ, five modes, 12 discrimination segments, three tones, 10 sensitivity levels and the V10 coil. Multi-IQ is the decisive advantage in conductive wet sand and mixed targets.
Both are land control boxes with waterproof search coils. Neither should be marketed as a wading detector. Compare shaft fit, batteries and exact headphones, then choose based on sites rather than uncontrolled depth videos.
