The RMR02 is constant on with self-adjusting brightness. Activation is instant. If the batteries have died, you use your regular irons just like any other pistol you've shot. You really have to try it to see just how large of an advantage it is. These pistols will be more and more common in the upcoming years. Mine is from OneSourceTactical btw.
