• No conversion of estimated target size from inches into decimal equivalent of yards is necessary, as the Target Size Scale is in increments of feet and inches.
• No entry of data or operations through a keypad is necessary, as the device is purely analog and only requires the alignment of figures on scales.
• No memorization of formulae is necessary, as the correct formulae are built into the scales.
• No complex calculations for determination of telescopic sight adjustment or hold-over at various ranges are necessary, as the scales of the device convert drop/drift figures directly into both MOA and mils.
• No separate data sheet is necessary for bullet drop figures, as the reverse side of the device is designed to accommodate either commercially available data decals or user-produced data strips.
