HW- 24 Handheld Non-Linear Junction Detector is an unique non-linear junction detector that is notable for its compact size, ergonomic design and weight.

It is highly competitive with most popular models of non-linear junction detectors. It can operate in continuous and pulse mode as well, having a variable power output. Automatic frequency selection allows operation in complex electromagnetic environment.

Its power output is harmless to operator’s health. Operation at higher frequencies makes it in some cases more efficient than detectors with standard frequencies but with greater power output.
