not to bad, i haven't been to the range yet to test out how spot on it is but have tried it on reflective signs, it reads 3mtrs closer than it was and can get a 400mtr reading from a car sized object any smaller and you have to use the scan function. to measure i have used the cars odometer and a tape measure so not sure if its spot on
it seems to read consistently so if its out at least you can work out by how much
for a cheap range finder it works well and would pick most things up, up to about 200 mtrs, talking rabbit size and using the scan, it also will reflect off bushes and trees (the leafy bits) which is handy. the scan function is the best bit as if you cant get a reading just scan it and most times you will get a reading,so much better than having to push the button while being as still as a rock
i like it, better than my old one by miles,,,,,,and yes the car sized object was in fact a car
