How do I know I can get onto the range I want when I come, just luck?

We have an online reservation system for members to use, in order to simplify your life and ours. It will allow you to see the availability of all range bays and reserve any bay for up to 4 hours at a time. Reserving a range only takes about 15 seconds. If you are on the range and approaching the end of your slotted time, and no one else has reserved it, you are able to reserve it for another 4 hours.
