-Comes on when it should and stays off when it should also. - easy to turn off after it turns on - bright and long battery life - fits securely in the arrow
Is there any brand that fits my wish list?
The post plunger in the center of a fixed nock seems to be best design so far. Nocturnal (push in) and glory nocks (spring action pop up) are much more reliable and reusable than the older designs where the entire nock had to move (luminocks and firenocks). My biggest gripe is for the money none of them are really consistent. Buy a dozen (which ain't cheap) and at least two or three are temperamental or complete duds. Given the cost they don't play well for daily practice as batteries go dead. The other headache is these aren't watertight so once they get wet there is a good chance of finding a corroded leaking battery a week later. If you buy some with the intention of simply installing on your hunting arrows and swapping out each season for fresh batteries I think either is great. Something you will shoot a few days every week, not so much.
But someone does come up with a good reliable one with replaceable batteries or ones cheap enough (like $1 each) to regularly replace, sign me up for a gross!
