Drill 127

The camera is placed at the side of the pool, filming lanes 2 and 3. Lane 1 is kept clear to avoid blocking the view. Swimmers in lanes 2 and 3 swim into the wall and then review their swims on iPads placed at the end of their lanes. The iPads are running on a four-split screen, showing each swim four times in a row. After reviewing, swimmers leave the wall again to repeat the drill.
