I would probably look for a used Shooting Chrony, it’s the one I use most. If it had to be new only, I would pick the Pro Chrono, I keep one of them at the farm and they too work well. I use them much more than the Pact XP I have but the additional data it can provide and print out, is nice.
I have played with the Labradar and didn’t get overwhelmed with enthusiasm. I generally keep it pretty simple.
On an overcast day, open the thing up, turn it on and shoot over it. Like in this video, I aimed the rifle at the middle plate of the plate rack on the right, down range, then took a step back and made sure the chronograph was below the path the bullet was going to be traveling.
If the ammunition is so inaccurate I can’t be certain I can miss a chronograph, just a few feet in front of the barrel, I don’t need to know how fast it’s going because I would never use it.
Down at the farm I shoot under 60 ft of shade often so getting muzzle velocity with a standard chrono isn’t possible. Once I have the load on paper, I just set the chronograph in front of the target.
Again, if a given load is erratic, I have no interest in knowing additional information about it. The only time I shot a chronograph was right after I took this photo, for the “how low can you go?” Thread. The next pellet bounced off the table and into the chronograph somewhere undetectable.
