{"product_id":"superior-shooting-systems-distance-reduction-indicator","title":"Superior Shooting Systems Distance Reduction Indicator","description":"\u003cp\u003eWhen firing up or downhill, an uncorrected aiming point results in a high shot. The shooter must hold less elevation than the same shot fired across level ground. Knowinghow much higher the bullet will impact becomes increasingly important as the distance to the target is increased, or as the angle becomes steeper, or both. \u003cstrong\u003eDavid Tubb's Distance Reduction Indicator (DRi),\u003c\/strong\u003e quickly and accurately indicates this \"Hold Closer\" distance and allows the shooter to determine the Effective Hold Point (EHP) to make an accurate shot. The \u003cstrong\u003eDRi\u003c\/strong\u003e is usable at any realistic distance.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eDRi\u003c\/strong\u003e eliminates the need for cosines as well as angle measurement.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eDRi\u003c\/strong\u003e is compact and rugged. It's engineeered to be low-profile and constructed to withstand the rigors of field use. The \u003cstrong\u003eDRi\u003c\/strong\u003e fits any standard Picatinny rail, and is level-adjustable over a 100-moa range to accomodate long-range-style scope mounts. With laser engraving along the side of the dial the \u003cstrong\u003eDRi\u003c\/strong\u003e is also readable from the spotter's perspective.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003e\u003cstrong\u003eHow it works\u003c\/strong\u003e\u003c\/u\u003e\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eDRi\u003c\/strong\u003e base is marked with \"6\" \"9\" and \"12\". These numbers correspond with 600, 900, and 1200 yards or meters. The\u003cstrong\u003eDRi\u003c\/strong\u003e is equally accurate using yards or meters.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eDRi\u003c\/strong\u003e dial has markings that correspond with theDistance Reduction markings on the base. The \"6\" and \"12\" have numeric values, the \"9\" splits the 6 and 12 values and is used to average\/interpolate. The large numbers on the dial indicate the hold-closer distance in yards or meters. Mounted correctly, the user can acquire the \u003cstrong\u003eDRi\u003c\/strong\u003e and then reaquire the sight with a minimum of movement.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003e\u003cstrong\u003eDRi In Use\u003c\/strong\u003e\u003c\/u\u003e\u003c\/p\u003e\n\u003cp\u003e*To determine the effective hold point (EHP), follow these steps:\u003c\/p\u003e\n\u003cp\u003e1) Determine the straight-line distance to the target.\u003c\/p\u003e\n\u003cp\u003e2) Aim the rifle at the target (this step engages the \u003cstrong\u003eDRi\u003c\/strong\u003e to provide a read)\u003c\/p\u003e\n\u003cp\u003e3) Determine EHP (effective hold point) for your distance.\u003cspan style=\"line-height: 1.6em;\"\u003e(This step can involve simple mathematical calculationsfor varying combinations of distance and angle.)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"line-height: 1.6em;\"\u003e4) When you have determined the correct EHP, locate the appropriate aiming dot within the scope, or adjust the scope knob.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003e\u003cstrong\u003eThe DRi difference\u003c\/strong\u003e\u003c\/u\u003e\u003c\/p\u003e\n\u003cp\u003eRifle mounted \"angle indicators\" and \"cosine indicators\" are on the market to determine the Effective Hold Point (EHP). \"Angle indicatos\" give their answers in degrees of angle (ex. 10û) which then must be input into the user's ballistic card\/data program to determine EHP. \"Cosine indicators\" give their answers by allowing the user to read a percentage (ex. 96%). The shooter then multiplies this percentage by the target distance to determine the effective horizontal distance to the target. That all takes time and, in the case of the cosine calculation, it's not very accurate at longer ranges.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe DRi eliminates the need for angle measurements and cosines\u003c\/strong\u003e. \u003cu\u003eThe calculations are simple, and the inputs are fast, direct, and accurate\u003c\/u\u003e.
