The focal airplane refers to the place the reticle is positioned throughout the scope.
First Focal Airplane (FFP): The reticle measurement modifications with magnification. This implies the holdover factors on a Mil-Dot or MOA-based reticle stay correct in any respect magnification ranges. Wonderful for long-range capturing the place holdovers are essential.
Second Focal Airplane (SFP): The reticle measurement stays fixed as you modify magnification. Holdover factors are solely correct at one particular magnification setting. Normally simpler to see the reticle clearly.
The selection between FFP and SFP typically is determined by the kind of capturing. FFP is mostly most well-liked for long-range precision capturing and tactical functions. SFP is commonly most well-liked for searching or functions the place simplicity is vital.
Eye Aid and Eye Field: Consolation and Precision
