A multi-contact type position detection apparatus for a target board includes a first membrane board having a plurality of first signal lines formed in a first direction, a second membrane board having a plurality of second signal lines formed in a second direction, and a plurality of dots which are formed on the first membrane board or the second membrane board such that the first membrane plate and the second membrane plate are spaced at a predetermined distance from each other, wherein the plurality of dots can be arranged at a distance of k/2A (A is 1%2% of k) when a magnetic body diameter of a pin attached on the target board is kmm.

Various systems, devices, processes, and techniques may be used for marksmanship training In particular implementations, motion data for a firearm may be acquired during live operation by a firearm operator using a sensor assembly coupled to a firearm. The motion data may be analyzed to detect a firing event, and the firing event may be used to pretrigger recording of the motion data. In certain implementations, the recorded motion data may be analyzed to determine inappropriate firing control actions, if any, and to provide corrective actions to a firearm operator about inappropriate firing control actions.

An early warning projectile penetration system includes a shoot house including a wall constructed of at least one inner layer of a ballistic penetration-resistant material, an outer layer of construction material, and a penetration detection system disposed intermediate the at least one inner layer and the outer layer. The penetration detection system is operative to provide an indication if a projectile has passed through the ballistic penetration-resistant material.
