Two underwater cameras are used. Camera 1 is placed at the side of the pool to film the turns in lanes 2 and 3. Camera 2 films the dolphins and the breakout. Both cameras stream to iPads placed at the opposite end of the pool from the turn. Swimmers swim in, make their turn, dolphins, and breakout, then review their swims on the iPads at the end of the lane. Compared to using one camera, this setup covers more than just the turn by also showing the dolphins and the breakout. A coach can also be involved, either providing live feedback on a separate iPad or recording one-on-one sessions with swimmers.
