Accuracy should be reasonably similar between units.
They will have maximums deoending on the ability of the emmitter and receiver and how good it is in variable reflectivity of the target.
The viewing optics and image clarity is usually where the most obvious difference lies. Had a few of thectypical LRFs and poor dark image is a typical realistic expectation. My Leica on the other hand is really good and easy to use it as a spotter as well as its intended task.
You dont need distance for air or rimmie but a good clear eyepeice image sure helps a lot and imho is worth the extra moolaaa
In a battle of wits I refuse to engage with an unarmed person.
To one shot one kill, you need to seek the S. Kill only comes from Skill
