I was taught this little trick by a competition shooter.
If your right handed and draw back, stick your thumb out and put it on the back of your neck to rest your arm while your hand is up by your anchor point.
It'll keep your arm from getting tired and shakey...
Excellent tip, that enabled me to hold at full draw for a couple of minutes while the deer came in.
Awsome.

Spotshooter, That is a 60 year old target archer's gimmick and I personally never subscribed to it, preferring to use proper back tension to hold at full draw rather than the arm shoulder and also to effect a clean loose...
The back does the loosing when done well.
...........but then, I'm not shooting 35# target bows for hunting, nor compounds which I need to hold for two minutes either...:)
I'm an aging heavy longbow-recurve hunter and killer of much game, and also have more than a few NFAA & PAA trophies indicating that I can shoot 'groups' under controlled situations..:)
Best advice I have for HUNTERS is to KNOW where your arrow will be at any point in it's flight to the mark for your chosen killing zone.
That takes practice.
Next and no less important is know the game you are hunting, the land and cover and their habits and get in sync with those..including the small birds and game which live there full time and serve as 'junk yard dog sentinels' for all but the stealthiest or least invasive intruders into their little worlds.
.
And of course, you must hit consistently even when at unknown yardages, up, down, in dim or full light and use an arrow with sufficient speed/weight equipped with a cut on impact b head..:)
Beyond all that, archery hunting is cake..:)Jim
