Yep, the separate display on the bench is much better as you can control it without moving from the bench. A few ideas are to use soda straws instead of the steel rods so that if you hit one it won't break the plastic sensor housing and put tape at 4" and 6" above the sensors as this is the ideal area you want the bullet to pass over the sensors.
If I need the sky screens and it isn't windy, I just take some sheets of paper, fold them in half, and tape them to straw extensions.
Another real plus to getting a unit with a remote computer and readout is if you loan your chrono to a friend and he shoots it. That way he'll only have to replace the sensors for $50, not the whole thing.
Go ahead, ask me how I know.
He made good on buying another.
