The Simple Marksman Adjustment Reference Table, or S.M.A.R.T. Card, was developed to provide a simple answer to the question we have all had on the range. “How many clicks do I need to move up an inch at this distance?”
While the concept is simple, amassing the data into a useful format was key. For example – The DeltaPoint Pro or Trijicon RMR moves 1” per click at 100 yards. But how does that translate on your pistol at 7 yards? The answer to that question is 1 click moves 4/57” at 7 yards. Great! That is useless information to someone trying to figure out how many clicks to move their adjustment. So it is simplified to 1/14 – so it would take 14 clicks to move it 1 inch at 7 yards.
All of the data was calculated for both yards and meters and the average was used. This number was then simplified to fractions of 1/* in order to give the shooter or coach a useful reference for how far to move that particular optic at the referenced distance. An example of this is that the M4 rear sight 3/4” per click at 100 meters. At 25 meters it moves 6/35”. To simplify this, we change this to 7/35” – or simply 1/5”. So now you know you need to go 5 clicks at 25 meters to move 1”. While we freely acknowledge that the mathematical conversions are not exact, we feel that the difference of 1/35” is negligible and the referenced measurement is much more useful as the simple fraction.
In addition to the data referenced on our wheel from 7m to 400 meters, the card also contains 2 rulers for measuring your groups as well as two trajectory illustrations for instructors to better explain this concept to their students.
The card is made from water proof die cut PVC so additional protection is not required for use on the range, in your field bag, or anywhere else. Measuring 5” wide and 4” tall, the card will easily fit in your uniform pocket, back pocket or range bag.
