Shooting Chrony Beta Chronograph SHTBETA

Measures the speed of bullets and other projectiles from 30 to 7000 fps. The chronograph can be mounted to a tripod or it can be placed on a table. It is made of 20 gauge steel, but weighs less than 2-1/2 lbs and uses one 9 volt battery (not included) for 48 hours of continuous use. It features a 60-shot memory, a forget button to clear individual strings and a jack for optional Ballistic Chrony Printer (sold separately). The Beta also stores data when turned off and moves instantly from string to string. Requires optional Indoor Shooting Light Fixture (sold separately) for use with florescent lights

# Has an adjustable size, triangular shooting area from 8"×8" to 14.5"×14.5". The sides of the triangular shooting areas are made of wire-rods; the top of the triangle is formed by a 2¼" wide x 1/8" thick strip of tough, Hi-density polyethylene plastic.
# The LCD-readout and all the Electronics are located in the housing, out front.
# Gives numbered shot velocities.
# Velocity stays on display until you shoot again.
# Measures High, Low and Average Velocities, Extreme Spread and Standard Deviations.
# Allows retrieval of individual shot velocity measurements.
# 60-shot memory (divided into 6 numbered strings from 2 to 10 shot each, with one set of statistics for each string)
# Can be switched off, taken home and switched on for reviewing, information retrieval or, together with optional IBM Interface downloaded onto your computer

# Not for use with Neon or other flourescent lighting, as they flicker at twice the AC frequency and cause false readings.
# For indoors, a light-diffuser and an incandescent light source must be located above each photo-sensor

In order to convert pellet/bullet velocity as measured by the Chrony into muzzle energy, the following formula is required. Don't worry, it's not at all complicated and it will be accurate; unlike the results normally achieved when using cheap plastic chronographs that attach to the muzzle and don't measure the velocity correctly but do the simple math for you.

The required formula is:

E = m x v2 ÷ 450240


E - This is the muzzle energy of the bullet (in foot-pounds force) i.e. the answer

v - This is the velocity of bullet (in feet per second) this needs to be squared i.e. multiplied by itself within the formula

m - This is the mass of bullet (in grains) This is normally declared on the tin or box that the pellets/bullets were supplied in.


For example, take an Air Rifle pellet that weighs 16 grains which is measured at a velocity of 600 feet per second when fired across the F1 Chrony. The resulting muzzle energy will be:


16 x 600 x 600 ÷ 450240

= 12.79317697 Foot-Pounds Force
