A top loop fits around the neck of a golfer. A bottom loop fits around the mid-section of the golfer. An intermediate section containing a breakaway unit connects the top loop to the bottom loop. If the golfer projects an acceptable swing, the breakaway unit does not disengage until the golfer reaches the follow through mode. If the breakaway unit disengages during the downward or ball contact mode, then the swing has not been satisfactory.
