The G200F4 finder grid offers a combination of new features. By using a rectangular mesh, the support value has been increased offering an intermediate between the most commonly used grid types; G200 (200 lines per inch) and the G300 (300 lines per inch). Each grid cell rectangle is asymmetrical having different outlines in all 4 corners. This enables orientation of the grid to be determined at microscopic levels. The index feature enables the position of the cell to be identified with reference to the letters A-O along the horizontal axis, and the numbers 1-15 on the vertical axis.
