I've tried several different kinds of lighted nocks and none can hold a candle to these Nockturnals. Custom fit to whatever arrow diameter you're shooting and super long battery life, it's what I run in all my arrows.
I’ve shot them all and nockturnal is by far the most consistent. Been shooting the green nocks for several years now but just shot a buck yesterday with the green/red strobing nocks and they are by far my favorite. Consistent activation, and absolutely awesome in flight. With the cost of an average arrow and broadhead,, finding them is beyond important and nockturnal has never let me down.
The battery life on these lighted nocks are pretty awesome. These nocks are a great tool to use in order to find your arrow after a shot. It gives you a way of figuring out shot placement by the blood on the arrow as well as a way of tracking your shot on camera when you go into playback to check shot placement. Great nocks.
DONT BUY! Get lumenok instead. These go off just by putting them on your string. Sitting in my stand now after 30 minutes of trying all 3 and lighting the woods up. Now I have to try and figure out how to nock a strobing arrow while a deer is approaching and somehow not get busted! For $30 come on!
