Backstroke Indicator

A backstroke indicator is a device used in swimming pools to help backstroke swimmers know when they are approaching the wall without having to look up. Here’s how it works and its key features:

Underwater Markings: Backstroke indicators are often installed on the pool wall underwater, usually about 5 meters (15 feet) from the end of the pool where backstroke turns are performed.

Visual and Tactile Signals: They typically consist of contrasting color stripes or bars on the pool wall. These markings provide visual cues to swimmers approaching the wall, helping them judge their distance.

Tactile Plates: Some backstroke indicators also include tactile plates or raised surfaces on the pool wall. These plates can be felt by swimmers underwater, providing a physical indication that the wall is near.

Regulatory Standards: Backstroke indicators are regulated by swimming governing bodies such as FINA (Fédération Internationale de Natation). They ensure consistency and fairness in competition by providing all swimmers with equal access to cues for turns.

Safety and Efficiency: By using a backstroke indicator, swimmers can maintain their speed and rhythm without needing to look up or slow down excessively as they approach the wall, thereby improving efficiency in their turns.

Installation: These indicators are typically installed at a consistent depth underwater to ensure they are visible and usable by swimmers of various heights and abilities.
