The Training Display Board features 24 inert circuit board training aids mounted to a 4’x 4’ board that represent a wide variety of blasting caps, explosive materials, switches, and power sources. Each inert circuit is configured to mimic a real circuit that could be detonated. The boards are removable from the main display and can be run through an X-ray. All of the IED components are exactly X-ray correct, including the explosive simulants.
