Alignment Considerations
For best results, you should always follow these alignment considerations while using your chronograph.
• Always observe the position diagram for your projectile type.
• Always ensure the large, flat side of the chronograph is pointed at the target and the screen is facing you.
• Always ensure the chronograph has an unobstructed view of the target.
• Always ensure the projectile can travel at least 20 meters or 20 yards in front of the chronograph.
Starting a Bow Session
NOTICE
Always ensure that you position the chronograph so that it is not directly exposed to ejecting cartridge cases,
muzzle blast, or other hazards that may damage the chronograph.
When you use the chronograph for archery, you should use a target that is at least 4 meters or 4 yards away
from you.
1 Select NEW SESSION > BOW.
2 If you have enabled the PROJECTILE WEIGHT ENTRY setting (
), select an option:
• To calculate the kinetic energy and power factor of your arrow, select YES, and enter the weight of your
arrow.
• To continue without calculating kinetic energy and power factor, select SKIP.
3 If necessary, observe the alignment diagram, and press OK to continue.
4 Point the chronograph at the target with the screen facing you.
5 Hold the bow over the chronograph so the arrow is 15 to 35 cm (5 to 15 in.) above the chronograph .
The device detects shots and displays measurements automatically as you shoot. The measured velocity is the
speed of the arrow as it passes over the chronograph.
