Mine definitely has distinct notches for on/off and sight brightness. For me it is almost a necessity for the smallest diameter pin. The brightest level is way too bright- in fact even the two lower levels might be a bit brighter than I would like. Would rather have one that is "infinitely adjustable" as I would like just enough light to see the pin I'm using. But am happy with this and would recommend getting it to compliment the sight.
Works great makes my sight brighter in the ground blind.
I have a Hogg Father and the when the light works it's great. My problem is it will continue to flicker on and off. Have to tap it in order for it to stay on. When I turn the dial to turn it off it doesn't do anything, I have to unscrew it out far enough for it to stay off. Very disappointed in the quality of light for such a high quality of site like the Hogg Father. Maybe I just got a one off?
This light is a must if use the small .010 pin. The first one I got arrived turned on...which was purely Fed Ex fault...but with what battery was left, each "on" click varied in brightness with wiggle of switch. I contacted Spot Hogg and they had a new replacement on my doorstep on east coast 2 days later!!! This one works perfect...so maybe it was just batteries being dead on first one but either way 5 stars for a company who stands behind their product!!!!
Added it to my spot Hogg sight and made a big difference in the ground blind..great sight light..
