Publication number: 20180081192Abstract: The present invention creates a new way of arranging harsh marks on a reticle that is to have the 2/10th and the 4/10th hash mark placed either above or below the horizontal base sighting line (See FIG. 2. Line 26) or on the left or right side of the vertical sighting base line (See FIG. 2. Line 27) at any unit of measurement of a segment and have the 6/10th and the 8/10th hash mark placed at the opposite side of the horizontal base sighting line (See FIG. 2. Line 26) and the vertical sighting lines (See FIG. 2. Line 27) compared with the 2/10th and the 4/10th marks. This new way of placing hash marks at every 2/10th of the unit of measurement allows a user to quickly identify and discern which numerical value a hash mark represents on the horizontal base sighting line and vertical sighting line without physically counting the numerical value of a hash mark in a linear way.Type: ApplicationFiled: September 20, 2016Publication date: March 22, 2018Inventor: Kevin Kai Qu
