F1 Archery Chrony

The best selling chronograph in the world has just become easier to use and at this price, there's no better or less expensive way to get into exact ballistics.

The Archery Chrony F-1, by Shooting Chrony Inc., comes with an indoor shooting light fixture which enables you to use your chronograph indoors.

The F-1 measures the speed of arrows and the velocity of bullets, shotgun pellets, airgun pellets and paintballs, etc from 30 fps to 7,000 fps and with better than 99.5% accuracy.

Designed with the bowhunter and archer in mind, your Chrony will go with you anywhere.

Unfolds just like a book, mounts on a tripod or can be placed on a table, insert diffusers, if needed and shoot in less than 2 minutes.

The speed and test number are displayed on the LCD read-out and stays on the screen until the next arrow is shot. Displays up to 32 arrow tests but it is suggested that you record your results in a note book or PDA because after 32 tests, LCD displays latest shot only unless Chrony is re-set.

The Chrony provides summary data such as Hi, Lo and Average arrow speeds, the total number of arrows shot, Extreme Spread - Hi speed minus Lo speed and Standard Deviation of string of shots as well as numbered shots.

It is powered by one 9 volt alkaline battery (not included) with 24 hours of continuous use and equipped with an extra large LCD readout 1.27 cm or 0.5" high.

When folded, the Chrony is 19.05 cm long, 11.43 cm wide, 6.99 cm high or 7.5" x 4.5" x 2.75".

Archery Chrony comes with a manufacturer's three year limited warranty, but will last a life time.

Chrony Test Record data sheet is included with information on how to evaluate your tests.

The F-1 Chrony is the basic ballistic work horse. It can be upgraded to any other Chrony model should you want more features in the future. Please enquire.

Comes with a huge triangular shooting window - an upside down trapezium from 20.32 cm x 20.32 cm or 8" x 8" to 36.83 cm x 36.83 cm or 14.5" x 14.5".

Chrony comes equipped with four 23.5 cm or 9.25" wire rods. The wire rods are inserted at an angle into the outer holes visible on the black plastic boxes of the unit.

On bright, sunny, blue sky days, install the white plastic diffusers on top of the wire rods to simulate clouds. The photo-sensors are pointed at the diffusers, which create a white background (clouds or diffusers). On cloudy days, use wire rods for alignment, but without the diffusers.

The bow being tested should be at least 3 metres or 10 feet from the Chrony and arrows must be clear of the bowstring before passing over the first "eye".

Chrony may be mounted on a camera tripod or on any adjustable device having a 0.64 cm or 0.25" by 20 thread that will screw into the hole on the bottom of the unit.

The F-1 is proudly made in Canada of 20 gauge steel housing for strength and less expansion and contraction deviation than plastic housings but weighs less than 1.1 kg or 2.5 lbs.

Easy to follow comprehensive instructions with diagrams are included in a robust cardboard box which can be used to carry the Chrony.

How does the Chrony work. It has two eyes or photo sensors located in each of the black plastic housings at the front and back of the main unit. They detect the passage of an arrow over the 2 sensors by sensing the change in the amount of light. They detect and measure a momentary change in light intensity.
