Walk Through Metal Detector Test Piece (OTP)

The OTP is designed to simulate a small handgun and a large knifes metallic signature in a walk-through metal detector. The test piece provides a more realistic test standard then just the "GUN" test objects and is much lower in price.

The OTP allows you to set your units detection level and also test your unit before each shift and verify it is working correctly, and the settings have not been tampered with. 

Comes in a small case and also includes instructions on how to use the OTP correctly.
