I've rented out some of their pistol/carbine bays twice now, they do require one of their RO's be present at each bay.  With renting the bay, the chief RSO allows for more flexibility on issues such as rate of fire, shooting from positions, etc...

I have not used their 1000 yard electronic target range yet, it's only open on weekends and has only been operational a bit over a month, I'm also not a shotgun shooter so haven't used those facilities.

It's located about 45-50 minutes NW of downtown Chattanooga.
