Need help?Do you have a question about the Caldwell 720001 and is the answer not in the manual?
Ensure a safe backstop and follow all applicable safety rules for firearms, airguns, and archery.
Do not use velocity measurements for cartridge or chamber pressure calculations.
Avoid armor plating; bullet ricochets can cause damage, injury, or death.
Understand that variables like lighting, wind, and reflectivity affect measurement accuracy.
Handle specific ammunition types carefully as components can damage the chronograph.
Velocity range up to 9000 FPS, requires 9v battery, operates 20-120F, has Smart Phone Interface.
Install a 9-volt battery into the designated compartment.
Insert rod ends into the rod pockets on the chronograph housing.
Attach Sun Shades to the rod ends, ensuring they are fully seated.
Place unit 10-15 feet from muzzle/bow; align height, tilt, and left/right for projectile path.
Turn unit on by selecting FPS or MPS using the power switch.
Connect to a smartphone via the included audio cable for enhanced functionality.
Install LED strips onto rods and connect to power source for improved performance.
IR LEDs improve performance; high output LEDs consume battery rapidly, lasting approx. 2 hours.
Understand indicators for ready status, velocity, duplicate alerts, errors, and low battery.
Download the 'Caldwell Ballistic Precision Chronograph' app from your device's marketplace.
Connect the chronograph to your smartphone using the 15' audio jack cable.
Be aware bullet path is lower than sight picture; aim higher than the middle of the shooting area.
Low light angles can cause variation; use the optional light kit for improved performance.
Remove dust from sensors using a Q-tip or canned air, being careful not to scratch.
Leveling ensures the projectile height is consistent over each sensor opening.
A stable platform like a table or tripod ensures proper positioning and alignment.
Shooting over snow or sand can cause reflections; use a dark tarp to reduce interference.
Overcast skies provide the best readings due to diffused light; avoid direct sunlight.
Remove Sun Shades in overcast conditions to allow more light into the chronograph.
Place chronograph in shade of building/wall for sunny days, ensuring sensors view the sky.
Florescent lighting can trigger sensors and cause false readings.
Stand one arrow length away; shoot arrows evenly over sensors at the same height.
Stand 5 feet from shotguns; be cautious of wads. Paintball guns can be fired from any distance.
IR LEDs enhance performance; use high-quality batteries for approx. 2 hours of optimal light.

The Caldwell Ballistic Precision Chronograph is a device designed to measure projectile velocity. It comes in two main kits: the #720001 Chronograph Contents and the #721122 Premium Kit Contents, with the latter offering additional features for enhanced performance.
The primary function of the Caldwell Ballistic Precision Chronograph is to accurately measure the velocity of projectiles. It utilizes sensors to detect the projectile's passage, calculating its speed in either feet per second (FPS) or meters per second (MPS). The device is suitable for a wide range of applications, including firearms, airguns, paintball guns, and bows. It can be connected to a smartphone via an audio jack cable, allowing users to access an application for advanced data logging and analysis.
