Turn Type

Currently, the TritonWear system supports three turn types - flip turns, open turns, or crossover turns. Here is a description of each:

1. Open Turn 

An Open Turn is a turn where the swimmer touches the wall, with one or two hands depending on the requirement for the stroke, and brings legs to the wall in a tuck-like position, then turning on the wall to face the opposite end of the pool and pushes off in a streamline to begin a new lap. Butterfly and breaststroke swimmers must touch with two hands; then one arm is typically dropped into the water to begin the Turn while the other comes past the head to complete the turnaround from the wall; from there the swimmer will push off into a streamline.

2. Flip Turn 

A Flip Turn is a turn where the swimmer swims to the end wall, tucks, does a forward flip, and pushes off in a streamline. While typically only executed during the backstroke or freestyle strokes, it is legal in all events provided that in butterfly and breaststroke both hands touch the wall simultaneously and immediately before the Turn.

3. Crossover Turn 

A Crossover Turn is used in the individual medley when changing from backstroke to breaststroke. The Turn involves a touch on the wall in the backstroke using your lead arm (the one toughing the wall) to pull your legs and do a backflip on the wall.
