Abstract: A gunsight reticle defines a system of dimensioned indicia spaced at specific separations to improve aiming accuracy of a gun. The indicia may include perpendicularly intersecting center vertical and center horizontal hairlines, and four (or more or less) horizontal range-marker lines disposed at specific angular separations below the horizontal hairline in bisected relationship with the center vertical hairline. Spacing of the range marker lines below the center horizontal hairline is proportional to bullet drop at selected ranges, depending upon ballistic characteristics of bullet used. Relative lengths of said range-marker bars on each side of the central vertical crosshair are proportional to a specific crosswind (say 10 mph) at target range reflected by respective range marker. The method involves employing this reticle to determine distance to target, and using distance thus determined to ascertain a precise aiming point on the reticle.

Abstract: The snag-resistant fishing lure is a snag-free fishing lure designed to minimize the chances of the lure becoming ensnared. The lure has a jig and a blade attached to the blade in a configuration that limits the side-to-side movement of the blade, thereby preventing the jig from rolling to a hook-downward position prone to snagging. A centrally aligned hole is positioned close to the front edge of the blade member. An eyelet extending from the jig body is attached through an aperture in the blade. The blade is limited in its side-to-side movement by contact between the blade edge and either the jig body or the eyelet. The limited side-to-side movement of the blade creates a quick, controlled, oscillating blade action that imparts a natural swimming motion to the lure, emulating prey species movements.
