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.
How do them straws hold out with a light wind. Seems that my outdoor range always has a light breeze, unless it's the dead of summer and you need one.
