Two operation modes: Allmetal mode and Identification mode Benefits: Choose Allmetal for wide detection of any metal, or switch to Identification mode to help identify targets and reduce unwanted signals. This provides flexible detection tailored to the environment and goal. Volume adjustment for speaker and headphones Benefits: Precise control of audio levels to suit quiet environments or noisy outdoors, and to match user preference for speaker or headphone listening. Pointer display for visual guidance Benefits: The pointer swings as metal is found, offering a visual cue to help locate targets and gauge proximity without relying solely on audio. Waterproof detection plate for shallow water searches Benefits: Enables searches in shallow water, along the shore, or at water's edge, expanding detection opportunities beyond dry ground. Use scenarios Beach and shoreline treasure hunting: Use Allmetal mode for broad sweeps along wet sand and near the waterline, then switch to Identification mode to help discriminate targets as you progress. Backyard or park coin and relic hunts: Start with Allmetal mode to cover large areas efficiently, then use Identification mode to focus on promising targets. Riverbank and shallow water exploration: Take advantage of the waterproof detection plate to search in shallow water while scanning for metal, expanding search areas beyond dry ground.
