LCD Waterproof Underwater Pinpointer

Built from impact-resistant ABS plastic, this portable pinpointer delivers precision detection in demanding environments. Its sealed housing achieves true 50-foot (15 m) waterproofing — verified for full submersion — and houses a responsive LCD that shows dynamic signal level changes in real time. Operating frequency is fixed at 10 kHz, optimised for general-purpose metal discrimination (ferrous/non-ferrous) without interference from ground minerals. Dimensions are compact for fingertip control, with slight physical variation (±1–3 cm) within acceptable manufacturing tolerances. Power management is intuitive: press-and-release to activate (confirmed by single beep); hold switch 1 second to deactivate. When battery voltage falls below operational threshold, an audible low-power alarm triggers, detection distance reduces progressively, and unit auto-shuts down after 10 seconds. Battery compartment opens via hand-tightened rotating cover; correct 9V orientation is guided by terminal-size matching (larger terminal → larger opening). For long-term storage (>30 days), battery removal is recommended to prevent leakage damage.
