Past 300 yards, guessing distance is how misses happen. Laser rangefinders from Vortex, Leupold and Sig Sauer give hunters and long-range shooters the exact number, and the ballistic models go further - correcting for angle and calculating holdover from your load data.
Bowhunters through ELR shooters all have a model here; the difference is ranging distance on soft targets, not the marketing number on the box. Ask us which spec actually matters for your use.
