SOTS M4: Point‐Initiating, Base‐Detonating (PIBD) w/ Piezoelectric
Part of the SOTS set, but also available individually here.
This model is special, the piezoelectric element in the nose is real and when depressed, creates a visible spark across a gap in the base fuze. There is no better way to teach students this concept than showing it to them "live" with this model; they can see (an feel if they so desire*) the cause and effect of a PIBD system.
It also incorporates the AOTM Color Code for intuitive learning.
Learning points specific to the M4:
- Shaped Charge
* Note: While the amperage of this system is very low and is very unlikely to cause any harm, we do not condone or recommended that individuals shock themselves or others with this training aid.
