Common questions about manuals, registration, and support for this brand.
Most models require you to attach the search coil to the lower stem, connect it to the upper stem, and secure the control box. Consult your specific user manual for detailed diagrams.
Generic metal detectors typically feature an ALL METAL mode for detecting all types of metal, and a DISC (Discrimination) mode to ignore junk metals like iron and focus on valuable items.
Sensitivity is usually adjusted via a dial or digital setting on the control box. Lower the sensitivity if you experience false signals in highly mineralized soil or near electromagnetic interference.
Many models feature a waterproof search coil, allowing you to search in shallow water. However, the control box is typically not waterproof and must be kept dry.
Continuous beeping can be caused by highly mineralized soil, low batteries, or a sensitivity setting that is too high. Try lowering the sensitivity or replacing the batteries.
