Horus Reticle
Also: H59 · Grid Reticle
A family of fine-grid holdover reticles, such as the H58, H59, and TReMoR series, that let a shooter hold drop and wind on the grid instead of dialing.
A Horus reticle is one of a family of fine-grid aiming patterns built by Horus Vision, including the H58, the H59, and the TReMoR series. Instead of presenting a few hash marks, these reticles fill the lower half of the field with a calibrated grid, so the shooter can place corrections precisely where the trajectory and wind call for them. The grid functions as a built-in ballistic table that travels with the line of sight.
The defining idea is holdover: rather than turning the elevation turret for each shot, the shooter reads the drop figure from a data card and holds that point on the grid. This makes a Horus pattern a kind of dense Christmas-tree reticle, and the approach reaches its most developed form in the TReMoR3, which adds dedicated wind and moving-target references to the basic grid.
