Build a hand set clean enough for beach officiating, where a double contact that passes indoors is whistled, and drill the bump set as the honest alternative.

Steps
01Set 20 balls straight up to yourself, watching for rotation on release. Any visible spin is the tell that the hands left at different moments.
02Have a partner stand behind you and call rotation on each set. You cannot see it on your own ball, so you need the outside eye.
03Fix rotation by getting both thumbs behind the ball and releasing with the wrists together, not by squeezing tighter.
04Now set 20 to a partner along the net, keeping the ball off-spin, and have them call any set they would whistle.
05Finally take 20 balls that arrive below your chest and BUMP set them instead. A clean bump set beats a doubled hand set every time on this surface.
Common mistakes
Setting a low ball with the hands because it feels more skilful, and getting called for it.
Releasing with one hand fractionally ahead, which shows up as spin rather than as feel.
Turning the shoulders during the release, which curves the ball toward the antenna.
