Too heavy or too light pellets ?

[Simplemann]

By understanding the operating principle of a conventional chronograph, you can adapt as needed. Light from above casts a shadow from the pellet onto the sensors. Being too close can potentially cause the muzzle blast (water vapor from rapidly expanding and cooling air) to occlude the shadow. Shooting too high may potentially produce such a diffuse shadow that it will not be reliably picked up by the sensors.

Thanks that's a great explanation

If I had a nickel for every "I shot my chrony" thread, I would thoroughly hate nickels.

Oh interesting so Caldwell is Made In China? The Competition ProChromo is Made In the USA.

Ohhh yes good point, so its feasible that the ProChromo has the same LCD display. Made In the USA means "assembled" in the USA nowadays .

So to continue to hijack here. What chronograph works well with .177 spingers and .22 rimfire?

Prefer less expensive options.

The ProChrono DLX will work from arrow velocities up to any center-fire cartridge. Paid $115
for mine but they've gone up in price. Accuracy to +/- .5%. The other (not DLX) ProChrono I think
has a accuracy rating of +/- 1%.
