MODELS: F-1*, M-1*, ARCHERY* and PAINTBALL-CHRONY*® as well as the
respective MASTER CHRONY® units for these Models. (*see page 9)

INTRODUCTION (** Please Read These Instructions Carefully Before Using The Chronograph)

SHOOTING CHRONY INC. assumes no responsibility, either directly or indirectly, for any action or consequences of any actions associated with the use of its products.

Every Shooting Chrony® measures the speed of bullets, arrow, shotgun-pellets, airgun-pellets and paintballs, etc.- from 30/FPS (feet per second) to 7000/FPS and with better than 99.5% accuracy. Your Chrony will go with you anywhere. Just unfold, mount on a tripod or place on a table, insert Diffusers (if needed) and shoot in less than 2 minutes. All Chronys come with a 3 year limited Warranty. The Master Chronys have the same capabilities as their respective Shooting Chrony counterparts. In addition to that, the Master Chronys have a LCD Monitor which brings the LCD (Liquid Crystal Display) readout right up to your bench, away from the bullets path.

Quick Setup Instructions

F-1 CHRONY
Gives Numbered Shot Velocities; + Velocity stays on display until you shoot again; + Uses 9 Volt Alkaline Battery with 48 hours of continuous use; + Stereo Jack for optional Remote Control or Chrony Ballistic Printer. The Chrony Ballistic Printer, will also function as a Remote Control. It prints velocities as you shoot and, on real paper. When done shooting, press STAT button on Printer and it will print Hi, Low and Average-velocities, Extreme Spread and Standard Deviation. !! This information becomes available only if and when the F-1 Chrony is used together with the Remote Control or the Chrony Ballistic Printer. !! + Upgrades to Alpha, Beta or Gamma Shooting Chrony or Master Chrony.

M-1, ARCHERY and PAINTBALL CHRONY
Same functions as the F-1 Chrony. However, Stereo Jack is optional. The Archery Chrony comes with the Indoor Shooting Light Fixture. The Paintball Chrony comes with Splatguard and Gun Cradle. The Archery and Paintball Chronys can also be used with Rifles, Handguns, etc.

As the bullet passes over the first detector, it trips a counter, which begins to count very rapidly (much as a super-fast stop watch). The counter is shut off by the second photo sensor when the bullet passes over it. The computer in the Chrony then converts this information into feet per second (FPS) or metres per second (MPS), whichever mode it was set to work in at the factory. The F-1 Chrony measures in FPS; the M-1 Chrony measures in MPS.

When used with a Remote Control or Chrony Printer, the computer inside the F-1 Chrony will, after the first shot, compute all statistical information, such as Hi(gh), Lo(w),

Av(erage) velocities, Extreme Spread and Standard Deviation, following each new shot. The use of our Remote Control or Chrony Printer gives access to the temporary working memory, which allows the erasing of part of the data . Only the Beta and Gamma Chronys have a permanent memory, which allows the unit to be turned off without losing data.

THE BEST WAY TO LEARN TO USE THE SHOOTING CHRONY
It is best to proceed slowly, safely, and have fun doing it. Getting the Chrony ready to use is easy.

Until you are familiar with the Chrony, shoot inexpensive ammo, such as airgun-pellets or .22 rimfire bullets. Doing so will save you money.

To get the following information, requires the use of a Remote Control or Chrony Printer:
The push button on the Remote Control is the equivalent of the FU button (or Function button) on the Chrony Printer.
The F-1 Chrony will provide you with summary data such as Hi, Lo, Average velocities and the total number of shots fire. Plus: Extreme Spread, Standard Deviation as well as numbered shots and retrieval of individual shot velocities.

etc., etc., repeat until all the shots have been shown, then -[ ]- appears. This means the end of the data and, that you are ready to shoot again. If you press the FU button again, you start the viewing cycle over again. Simply pressing and releasing the FU button takes you from one piece of data to the next.. If you wish at any time during the viewing process to return to the working mode, stop pressing the button and wait 15 seconds. It returns to the working mode by itself. Sometimes, if you hold the FU button down for more than two seconds at a time, the unit will go into a sub-menu. Wait 15 seconds, it will return to normal by itself. When you think that you may have done something wrong, take your hands off, and it will go back to normal by itself. Features like this make the Chrony very forgiving and easy to use.

A) PROBLEM: =Lb=flashing. Cause & Remedy:
Battery is low and must be replaced.

D) Err 1 shows on screen; the first sensor did not detect the passage of the bullet. This means either that the shot was not fired directly over the centre of the first sensor, or, that there are poor light conditions. Be sure that the Chrony is aligned with the line of fire.

E) Err 2 shows on screen; the second sensor did not detect the passage of the bullet. Same as above: poor light or poor alignment.

F) Err 3 through Err 8 shows on screen; the exact number relates to internal codes, and is of no significance to the user. May indicate poor light condition. Installation of Diffusers may help.

G) Low velocity reading. Light conditions not right; try diffusers. You may be shooting during poor light conditions.

H) False reading (usually high); can result from very strong light, or by operation near electric motors, radar, powerlines, electric fences, static electricity, radio transmitters, etc. It may also be caused by the Chrony being too close to the gun’s muzzle. Remedy: try using diffuser, moving away from electrical interference, moving unit farther from the muzzle, or all of these.

I) Very high velocity readings: 1) can result from muzzle blast; move Chrony farther from muzzle; 2) Chrony is not fully open; check for interference from tripod or base.

Make allowances for temperature differences between chronographing your loads and their use in competition. In cold weather, powders burn more slowly and will produce lower velocities than they will at higher temperatures. Different altitudes may also affect velocity. Loads developed which are near maximum velocity during cold weather may produce dangerously high pressures and be unsafe during hot weather. Always try to match conditions while chronographing with those conditions you will face when shooting or hunting. That is, if you hunt in late autumn, do the chronographing in late fall.

On sunny days, at certain angles, light may reflect from the bullet and cancel the bullet’s shadow. Mark the bullets all the way around with a dark-coloured felt marker if this seems to be happening.

On sunny days, the Chrony may be tilted sideways toward the sun, so that the Diffusers are between the sun and the photocells. Be sure that the Chrony unit remains fully open, and that it is perfectly aligned with the target. Using diffusers on cloudy days may shut out too much light.

Using diffusers on cloudy days is not necessary, since you have the clouds as a white background for contrast.

The Chrony reads velocity in feet-per-second (or metres-per-second) and works in a velocity range from 30 fps to 7000 fps (10 mps to 2134 mps). Operating Temperature range: 32o Fahrenheit to 110 o Fahrenheit (0 o Celsius to 43 o Celsius), non-condensing. (Ambient temperature must be above dew-point temperature and not fall below dew-point temperature while Chrony is being used.) Storage Temperature range: 14o Fahrenheit to 120o Fahrenheit (-10o Celsius to 50o Celsius) non-condensing. (Ambient temperature must be above dew-point temperature and not fall below dew-point temperature where the Chrony is being stored, unless the Chrony is sealed in an air-tight container.)

Accuracy: 99.5% or better. Displayed velocity will not differ from actual velocity by more than 1 part in 200, i.e., ±10 fps on a velocity reading of 2000 fps. Typical performance is generally better, and shot-to-shot repeatability is always more accurate, i.e., Reported Mean Instrumental Velocity may differ by as much as 0.5% from actual mean instrumental velocity, but Standard Deviation calculated from data gathered with a Chrony will always be closer than 0.5% to actual Standard Deviation for a string. This is an important fact because an accurate measurement of a load’s uniformity is of considerably more importance than is an exact measure of its average velocity.

LCD Display: 0.5" (1.37 cm) high; Weight: 2.5 lbs (1.2 kg).
Battery life: 48 hours of continuous use. Photo sensors have wide sensitivity range, and are electronically calibrated to obtain maximum accuracy.
Should you have to return your Chrony because of a malfunction, do not return it to the Dealer, Distributor or Mail-Order House you bought it from. It must be returned directly to SHOOTING CHRONY, INC.
