1. Product introduction:
ST-402 Non-linear Node Detector is specially designed to find and detect electronic equipment hidden in walls, floors, ceilings, fixtures, furniture or containers. No matter if the target electronic product is radio frequency, wired or closed, you can use the product. Any modern electronic equipment contains semiconductor components, so these components can be easily and quickly found using nonlinear node detectors

2. Product features:
Low power consumption, high detection sensitivity;

Strong anti-interference ability, which can effectively eliminate the interference of steel materials and corrosive materials;

Low error rate: The product can work in a wide frequency range, and the processor stores a large amount of reflection spectrum information to ensure detection accuracy;

Humanized design: larger telescopic sleeve and telescopic handle make users feel more comfortable and natural to use;

The equipment uses 2 batteries and has a battery life of up to 4 hours. The standard configuration provides 4 batteries for replacement, which increases the normal working time to 8 hours;

Equipped with 1 shockproof police box.
