How it differs from its neighbors
The GPX 6000 is Minelab's other pulse induction model on file. It is lighter, 4.6 lb, with a DD and a monoloop in the box. Its coil alone carries a rating, to 3.3 ft (1 m).
From Garrett, the Axiom comes in at 4.2 lb with the 11-inch mono coil, lighter than the GPX 6000. Garrett gives it no water rating that we could find.
At the heavy end, Minelab's GPZ 7000 weighs 7.32 lb and is not pulse induction but ZVT.
