Hi! It's time to change the battery but I can't seem to find where it's put? I've tried google and I've read the manual without finding an answer.

Asked by: WSten
Hello, The battery is located on the end of the illumination dial. The end will screw off and the battery is in there.

H, dose the illuminated red dot have different brightness levels! if so how many?

Asked by: Blair
Hello! The Nighthunter Xtreme line uses a rheostat switch for illumination. Like a dimmer on a bulb, you just hold it until you get the light level you want, from none to very bright.
