- Wait for the detector's temperature to stabilize if it has been exposed to significant temperature differences.
- Avoid using microwave ovens or other emission devices near the detector.
- Environmental factors like proximity to machines producing strong magnetic or electromagnetic fields, moisture, metal-containing building materials, aluminum-coated insulation, conductive wallpaper, and carpets can affect detection results.
- Always refer to relevant instructions (e.g., architectural drawings) before drilling or sawing walls, ceilings, or floors.
- Turn off power, gas, and water supply before drilling or nailing through walls with live wires.
- Remove jewelry like rings or watches when using the detector to avoid interference.
- Move the detector evenly on the wall surface without lifting or changing pressure.
- Maintain constant contact between the tool and the wall surface during scanning.
- Ensure fingers holding the tool do not touch the scanned surface.
- Avoid touching the detector or scanned surface with other body parts.

The Product operates well, within few seconds detects hidden metal or wood. It does require however a bit of reading the product manual to understand how to operate it and the meaning behind the ring colors, could be a bit more straight forward. The quality of the device feels pretty good as well.
Arrived extremely well packed maybe even exaggerating for an already boxed product. Seller communication is excellent, even before arrival provided information and link to instruction manual, thank you.

Wilton Stroman

Delivery to Ukraine in 7 days. The device is very good. The menu has Russian language. There is also an instruction on the Russian. The description is very competent. The device checked on all modes. Everything in the description, everything works. Read carefully the instructions and watch the video on the Internet. When searching, calibrate more often, because the scanner is very sensitive. Don't expect miracles. When looking for electrical wiring in the apartment, he will find everything. What is in the wall, fittings, pipes. Wire, can react to voids and so on. Remember, in old high-rise buildings, the electricians did not shank the walls, they cut wires into the cracks between the slabs and into the voids in the slabs themselves. Annoying buzzer easily turns off in the menu. In short, if you learn how to use it correctly, then this is not a device, but a masterpiece. I am very satisfied with the purchase.
