WHEN MAKING ADJUSTMENTS, LOADING FIREARM AND
DISCHARGING FIREARM. CARE SHOULD BE TAKEN TO ENSURE

SLING OR ACTION.
WARNING! Never exceed published recommended gun
powder amounts in reloads to achieve higher velocities in your
ammunition. Increasing the amount of powder could cause a
dangerous condition that may cause property damage, personal
injury or death.
WARNING! Velocity measurements should not be used to
calculate combustion pressures in your cartridge or chamber. Again, do
not exceed published maximum powder levels in your ammunition.
WARNING! do noT try to protect your chronograph with armor
plating. Bullet ricochet from hitting this plating could cause property
damage, personal injury or death. Chronograph components are
replaceable.
All chronograph units have inherent uncertainty when recording
velocity measurements. Several uncontrollable variables can affect
each measurement and contribute to this uncertainty, including sunlight
intensity, sunlight orientation, cloud cover, wind, shadows, and ground
reflectivity of cement, water, or snow, etc. When collecting data, be
suspicious of any data points that have greater than a 4% difference of
that ammo’s average string velocity.
Special care should be taken when shooting certain types of
ammunition. gas checks, wads, sabots, etc. can separate and impact
your chronograph causing damage to the device.
Also, as with any electronic device, water can damage certain
components. Be careful when using the chronograph outdoors in rainy
weather to prevent damage to the Keypad/Display Unit or Skyscreens.
