Shooting Chrony Chronograph...An Affordable Chronograph for Measuring Bullet Velocities...
Bullet Velocity... It's a simple number that opens up a world of possibilities for rifle shooters. Knowing your actual, real velocity lets you calculate your actual, real trajectory. Use your Chrony to check the consistency of hand loads and/or factory ammunition. (Usually, ammo with the most consistent velocity from one shot to the next will be the most accurate). The Shooting Chrony includes all of the electronics and sky screens for reading velocities from 30 feet per second (fps) to 7000 fps. Just set it up on a tri-pod or bench 10 feet in front of you and fire thru the center of the V rods and sky screens. The Chrony will measure the velocity with 99.5% accuracy. Standard Models have the read-out directly on the Chrony (see left). Master Models have a separate read-out unit that sits with you on your shooting bench. The various models measure equally well.
F-1 and F-1 Master Chrony - Gives
numbered shot velocities, velocity stays on display until
you shoot again, has a jack for the Chrony printer, and
upgrades to any of the more sophisticated Chrony models.
For using ballistic software like Sierra Infinity Six, all
you need is to measure your velocity and average it out
with a calculator. The F-1 is the simplest and least
expensive chronograph that gets the job done.
Alpha and Alpha Master Chrony - All of the F-1 features PLUS 2-32 shot memory (one string). Alpha Chrony calculates high, low, average, extreme spread, and standard deviation. Retrieves and even edits individual shots and stats from memory.
Beta and Beta Master Chrony - All of the Alpha features PLUS 60 shot memory (6 strings) with stats for each string. Has retrievable memory after powering down.
We recommend you also buy Infinity Seven Ballistic Software... type in your velocities and Infinity Seven will calculate trajectories, wind drift, energies, momentums, points of aim, bullet paths, etc.
