Tap a row to set the distance. V1 = chrono distance D1. POI = impact vs line of sight (+ above / − below). DROP = trajectory vs bore axis (− below). T = transonic (Mach 1.2–0.9), S = subsonic.

Shots numbered 1 → newest (highest number at the bottom). Tap a row to show that shot as V1 on the panel. ✕ deletes one shot, hold CLS on the panel clears all. The chronograph sends one velocity per line in the current units (m/s or ft/s).
