Disclosed is a method of aiming a firearm operated by an operator, comprising: a) at a range-determining rate of at least as frequent as once a second, determining the range to an object along an aiming line of a firearm; b) generating a signal audible to the operator, wherein at least one characteristic of the audible signal is modulated as a function of said determined range; and c) discharging the firearm in response to the characteristic of the signal. Also disclosed is a device useful in helping to aim a firearm, comprising: a) a range-determining unit configured for mounting on a firearm, further configured for determining the range to an object along an aiming line at a range-determining rate of at least as frequent as once a second; and b) a reporting unit functionally associated with the range-determining unit, configured to generate a signal audible to a human operator, wherein at least one characteristic of the signal is modulated as a function of a range determined by the range-determining unit. Also disclosed is a firearm comprising: a firearm body including a barrel having a muzzle at a distal end; and mounted on the firearm body, a range-determining unit of the device useful in helping to aim a firearm. |
