The BDX system works out to 800 yards with 1 MOA of accuracy - CONNECT THE DOT™: It’s time for hunting. Once the riflescope is turned on, range the target and the new hold is lit up out to 800 yards
PRS Shot Timer

PRS Shot Timer is a par timer and shot timer built for precision rifle shooters. PRS and NRL stages run on the clock, so this app puts that clock in your pocket and lets you practice stages exactly the way you shoot them. PAR TIME STAGES Set your stage par time, hit start, and run it. Audible start beep and end-of-par signal, so you learn what 90 or 120 seconds actually feels like from behind the rifle. SHOT DETECTION AND SPLITS The timer picks up your shots and records the time of each one, giving you your splits and total time. See where you are losing seconds: the first shot, the transitions, or the position changes. POSITIONAL DRILLS Build drills around the positions you actually shoot. Barricades, tripods, tank traps, rooftops and awkward props. Set a par, run the position, and track whether you are getting faster. DRY FIRE PRACTICE Run par times in dry fire at home. Position building, bolt manipulation, and transitions cost nothing to practice and are where most stage time is won. SESSION LOG Every run is saved. Review your times, compare drills, and watch your progress across a season instead of guessing. BUILT FOR RIFLE Designed around centerfire and rimfire rifle shooting rather than pistol, including the realities of muzzle brakes and suppressors on the line. METRIC AND IMPERIAL Full unit support wherever you shoot. FREE No ads. Core features free. PRS Shot Timer is a practice and timing tool for organised, safe competitive shooting. Always follow range commands and safe firearm handling practices.
