Just got a PH 5-25x and after some fiddling... found out I can slightly rotate the illumination knob to a point where the reticle will flash red on/off repeatedly. This seems like it'd be great for quick target acquisition (Not sure when that would ever be handy for me lol), but I was wondering if this would be beneficial/harmful. I was thinking it might be like those Glock LaserMax lights where the flashing helps battery life, or am I potentially damaging my scope/battery life?
