I set up some of the lights with a click and others with a smooth silent feel. There are two camps out there on this issue and the verdict is still out. I myself prefer the clicky sound like Dad's light probably has.
The mechanics of it are effected by the slot width in the switch and the corresponding width of the blade in the knob. It is also effected by the knob adjustment nut. You can not change the slot in the switch but the blade width can be modified. Few of the lights have a truly quiet knob because that requires very tight tolerances in several areas. Without voiding the warranty you can not change it yourself.
The knob adjustment nut pulls the knob tight against the o-ring. If it is loose the knob has a free turning feel but it is not as water tight. I carefully set them all to be water resistant because that yields the best compromise to feel. However, if water gets past the o-ring it still does not go anywhere because the Teflon bushing and grease in the bearing stop it there. You can't have water getting inside the SPY or it will need to be opened and dried out. It is OK in the rain but don't put it through the machine wash cycle.![Caution :caution: :caution:](/styles/default/xenforo/smilies/3/caution.gif)
