Abstract
The invention concerns a fire arm equipped with an enabling system which comprises a transmitter/receiver (6) of ultrasonic waves mounted on the fire arm, a unit (5) to be carried by the shooter, containing means (13) for sending back a signal transmitted to the latter by said transmitter/receiver (6) and a monitoring device (9) monitoring the signal received by the above-mentioned receiving part, controlling a device (10) which can prevent any firing. The enabling system contains a timer (7) which can measure the length of time between the transmission of a signal by the transmitter/receiver (6) and its reception by the latter, and a device (8) to calculate the distance covered by said signal, whereby the monitoring device (9) only makes it possible to fire when it recognizes the signal and when on top of that the above-mentioned distance is inferior to a certain limit.
