The Garrett Vortex VX7 sits in Garrett's lineup alongside Garrett ACE 400, Garrett ACE Apex, Garrett AT Max, Garrett AT Pro. It uses Simultaneous multi-frequency — transmitting several frequencies at once and combining the returns. Near-VLF discrimination with near-PI ground handling: the processor subtracts the salt/ground response while keeping target signal. Costs more and drains batteries faster, but it's the best all-round answer for mixed ground. Compare it against its intended competition in our guides to the best beach metal detectors, and see how Garrett's range stacks up on the Garrett brand page.

The Garrett Vortex VX7 is a strong pick for intermediate detectorists, saltwater beaches, parks, fields and freshwater detecting, but no machine is universal. Check the waterproof line before any water use, confirm the weight against your stamina, and remember that ground conditions affect real-world performance more than any spec number.
