🏆 Our Top Pick
ACE 400

If you’re torn between these two, find the extra £50 and get the ACE 400. It ships with a DD coil as standard (the 300 comes with a smaller concentric that struggles on trashy sites), gives you more depth and separation, a wider 0 to 99 target ID and electronic pinpoint. The 300 is still a perfectly good first machine, but the 400 is the one you won’t feel the itch to upgrade from quite so soon. For a beginner watching the budget, the 400 is the smarter spend.
