HAD A JUMP BALL. THE ARROW WAS POINTING IN A'S DIRECTION. SO WE GAVE IT TO A. PLAY GOES ON FOR A FEW SECCONDS WHEN THE TIMER BLOWS THE HORN AND PLAY STOPS. SAYS THE ARROW WAS POINT WRONG DIRECTION. SHOULD HAVE BEEN B'S BALL OUT. IS THIS A NON CORRECTABLE ERROR?

Yes, it's non-correctable. Let A keep the ball and point the arrow in B's direction.

I'm of the old school and I use my extra whistle as my possession arrow on court. Facing the table the whistle is in the pocket in which the arrow should be pointing. I check it on ever dead ball.
This was not a correctable error. But if you have definite knowledge you can over rule the table.

I too use a something (an NFHS coin actually) to verify the jump ball. It's become a part of my game, and I check it almost every dead ball. It has saved me many times.

This is non-correctable.

A rubber band on your wrist will work ok also. This way you are not grabbing at yourself to find an extra whistle etc.

not groping anymore....
 

I just started using a black rubber "O"-ring on my finger.
<u>White is right.</u>.

I cannot use my wedding ring because it's too tight to move easily, ...even harder cuz I don't wear it all the time.

Someone suggested the "O"ring on one of these forums, not my idea.

Our association prohibits us from using rubber bands on the wrist for two reasons: 1) we cannot "wear" anything like that which we would not let a player wear and 2) it looks too much like volleyball ;)

Personally, I move my handkerchief from front pocket to the other front pocket to match the bench as I am facing them as to who gets next possession.

I would rather not depend on these memory devices to
help me with the arrow direction. Unless I've
gotten roped into one of these run-til-you-drop-
multi-game-marathons I keep the arrow in my head.
Even then by the time I get fuzzy enough to need the
rubber band I can't remember if I changed hands last time
out so I just make sure the folks at the table are working the arrow correctly at each AP situation.

As a side note:
You can correct an AP error. The mistake can be corrected until the throw in is touched inbounds by a player. (Federation Casebook play 6.3.1D)do not allow a team to have sucessive AP throw ins.

I do not believe in rubber bands, not an o-ring. I think something that is not visible is viable though. Either an extra whistle in the pocket, or whatever. It's part of my game now - in two years I've been using it, it's never let me down.
