Some have a very short distance between the two lights. While this is good for being compact, it can lead to incorrect readings if the pellet is not shot at exactly 90 degrees to the light source. In the chronograph world, you really only have two options: The expensive complicated units that gives you most of what you need, but cost far too much, or the cheaper models that are outdated, not very portable, are light sensitive/dependent, and often break easily. The centre fire capable chronogaph not only records and logs your strings, but also gives Ballistic Calculations and data to help you improve your loads / tune to gain a greater understanding of how your setup will perform in a real world environment.

The unit tells you everything you need to know to determine if your gun is working as you expect it to be. Also note that the FX app allows you to make manual calibration adjustments of up to plus or minus 2%. So it would be easy to adjust the FX Chronograph readings to exactly match that of the reference chronograph – assuming that the AAFTA-designated unit was 100% correct, of course! Hmmm…Note: We will not be able give any guarantees of function or liability, neither will we be able to give any support to 3D printing.

Going through each screen gives an impressive selection of inputs that can have you using everything from a airgun high power to a nerf gun.

This is also true for any firearm. Yes, no sensitivity settings needed as it seamlessly reads any projectile between 400 to 4000 fps without pressing any button. IMPORTANT - .177 SHOOTERS - FOR BEST RESULTS PLACE THE CHRONOGRAPH 2 INCHES / 51MM FROM THE MUZZLE. The placement from promotional photos of the chronograph on the scope or a distance from the muzzle does not work in .177. If you have been shooting airguns you should have access to a chronograph to test the health of your gun. Airgunners want to know the velocity and power coming out of their rifle. This is especially important with FX Airguns that allow the ability to tune, change calibres, and change barrel liners. A chronograph is a key tool needed to maximize the accuracy of your rifle.The app records speed, custom profiles, calibres and gives multiple readouts depending on what you require. Store and save your data, or export it to use in other programs. The App can call out the numbers as you shoot, so no need to take your eye off your target.
