Back Wall Sensor, Base Search, Wall Back Search, For Interior Materials, Wood Detection, High Sensitivity, 9V and Japanese Manual Included ST100

[Why do I need a back-wall sensor?] ] 90% of the walls in Japanese homes are made by attaching gypsum board to a base such as studs. Gypsum board is brittle and easily crumbles, so before you drive screws into the wall, you need to find the underlying material behind the drywall. The SupltuX wall detector has a detection depth of 3/4 inch, and mainly detects wood behind walls, and also measures the detection range of metal and AC power lines to safely avoid them and insert screws etc. into the middle of the wood. [Auto Calibration Function & One-Key Operation] Press and hold the start button with the substrate sensor against the wall, and the ST100 detector will automatically adjust and calibrate the sensor sensitivity depending on the wall fabric. Then, hold down the button and slowly slide it without letting it go away from the wall to measure the wood behind the wall. [Double Sound and Light Reminder]▶When the substrate finder is automatically calibrated, the red and green lights will always be on and the buzzer will sound;▶When you reach the edge of the wood or close to the metal or AC wire, the LED lights will turn on in sequence and the buzzer will keep beeping;▶When the power is low, the green light will keep blinking, please replace the new one. [Precautions while using] ① Every time you leave the base sensor away from the wall, you need to calibrate it again before measurement; ② During measurement, press and hold the button and move slowly; ③ If the calibration position is above the target (wood, metal, AC wire), the base sensor will not be able to detect the target. At that time, please change the calibration position and recalibrate; ④ To improve the accuracy of detection results, it is recommended to measure multiple times.
