The MINI-04 differs from the MINI-02 because it has the 2-Pin Plug connector already hooked to the cable.

MINI-04 is worn on the fencer's wrist by means of the practical Velcro® wristband.
MINI-04 signals each time the foil tip is pressed. Valid points are not therefore distinguished from invalid ones, and neither the points on the piste nor the ones on the adversary's guard are disabled.

It is ideal for training as there is no need for wire spools, pistes, cables or signalling equipment.
