Yes and no.
One of the guys got a sig 10k last weekend and went to the targets and shot back to the line to get range for everyone. It was right within 1 yrd of my sig 2200 so it worked for everyone.
If I don't know who shot the ranges with what rangefinder, I'll still hit it myself. Sometimes they're on, sometimes they're wildly off.
The SIG stuff is cheap and works great. You have to spend a lot more to get anything better.
