Shooting Chrony Chronograph
Made of 20 gauge steel.
Has a large LCD-readout, 1/2" high.
Has an adjustable size, triangular shooting area from 8" to 14-1/2".
The sides of the triangular shooting areas are made of wire-rods; the top of the triangle is formed by a 2" wide x 1/8" thick strip of tough, Hi-density polyethylene plastic.
Gives numbered shot velocities.
Velocity stays on display until you shoot again.
Measures velocities from 30 fps up to 7000 fps.
Can be mounted on a tripod.
Not for use with Neon or other flourescent lighting, as they flicker at twice the AC frequency and cause false readings.
For indoor use, a light-diffuser and an incandescent light source must be located above each photo-sensor.
