1. A locking adjustment device for adjusting a setting of a riflescope or other aiming device, the locking adjustment device comprising:

  • a knob mountable for rotation about a rotational axis when the locking adjustment device is installed on the riflescope or other aiming device, the knob rotatable in a first direction and in an opposite second direction about the rotational axis;

    a catch including (i) a first member attached to the riflescope or other aiming device and constrained from rotating about the rotational axis, and (ii) a second member supported by the knob for rotation therewith, wherein the catch defines a home position of the knob at which the first and second members automatically engage with one another to prevent further rotation of the knob in both the first and second directions relative to the first member when the knob is at the home position; and

    a lock-release mechanism carried by the knob for rotation therewith, wherein the lock-release mechanism is manually actuatable to disengage the catch and allow the knob to be rotated from the home position to an adjustment position at which the knob is rotatable to further adjust the setting of the riflescope or other device, and at the adjustment position and all rotational positions about the rotational axis other than the home position, the lock-release mechanism being releasable without impeding rotation of the knob in at least one of the first and second directions relative to the first member.
