05 February 2024 0 8K Report

There are several ways to categorize metal detector types, but we will use three that are fairly popular with practically all detector engineers:

1. Frequency shift

2. Induction Balance

3. Pulse Induction

i want to know the best technic te realise portable metal detector for access control
