Paintball Guns
Muzzle to chronograph distance is not a factor with paintball guns, however
paint buildup on the unit may affect its performance. See the CEI Debris Shield
in the accessories section of this manual, it can provide an additional measure of
protection.
Airguns, BB Guns, Pellet Guns & AirSoft Guns
Muzzle to chronograph distance is not a factor with these types of guns. The main
issue is that BB’s are probably one of the most difficult projectiles to measure
using light-based techniques because they are small and shiny. However, with
proper setup and lighting conditions the ProChrono LTD will measure them
reliably.
Miscellaneous
You may think of other uses for the chronograph. For example, some have used it
to measure the speed of sporting clays. If you can get it to pass over the sensors,
you can probably measure the velocity.
Battery Installation
Begin by installing a new 9 volt alkaline battery in the chronograph battery
compartment. There is also space to store a spare. You can expect at least 20 hours
of operation from a new alkaline battery.
Mounting the Chronograph
The chronograph may be placed on a sturdy table or mounted to a tripod
using it’s molded-in 1/4-20 threaded insert. Be careful to prepare adequately
for windy conditions, especially if you are using a tripod. The diffusers make the
chronograph susceptible to wind gusts.
