Hilti's good name is with there service, better than hilti, they all claim the same accuracy.
so it comes down to personal choice.
I own a Top-con, have had it for 6 yrs. with zero problems.
If I was working back in the states I probably would go with Johnson's Rotary laser levels, American made and all that bull.
And green lasers are for seeing better the lasers light indoors, for external you still need a beeper.
they cost more too because of how they got to make the light green,
has nothing to do with accuracy
There are ones better than the hilti, They just have a good name.
Depends what your doing with it.
I have a Bosch that works great for what I use it for (outside work, with in 100' usually) but some of them can shoot crazy far using a green laser.
How much you wanna spend?
