The Minelab Vanquish 340 is a strong pick for beginners, coin shooting, jewelry hunting, parks and beaches 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.
