The SEIKO Underwater Lap Counter System is designed to help swimmers accurately keep track of the remaining number of laps during long-distance swimming races. An underwater display board installed in each lane provides a clear visual indication of the remaining laps, allowing swimmers to monitor their progress without relying on external signals.

Operating in synchronization with the swimming printing timer, the system automatically calculates the remaining number of laps and transmits the information to the underwater display boards. The two-digit, high-intensity LED display provides excellent visibility, helping swimmers maintain awareness of their race progress and supporting the safe and smooth operation of long-distance competitions.

Real-Time Lap Tracking for Swimmers

An underwater display board installed in each lane provides a direct, clear visual indication of the remaining laps. This allows swimmers to confidently monitor their own progress during long-distance races without relying on external signals or deck officials, reducing the risk of miscounting.

Automatic Calculation & Synchronization

Operating in seamless synchronization with the swimming printing timer, the system automatically calculates the remaining number of laps as the race progresses. This automated process eliminates manual tracking errors and ensures that the data transmitted to the underwater displays is always accurate and up-to-date.

High-Visibility Underwater LED Display

The two-digit, 7-segment high-intensity red LED display features a large 45 mm character height, providing excellent visibility even in poorly lit aquatic environments. The durable stainless steel construction with a protective yellow matte acrylic resin coating ensures long-lasting performance underwater.

How the System Works

1. Race Information Is Entered – The required race and lap information is configured through the operation board.

2. System Synchronizes with the Timer – The system operates in coordination with the swimming printing timer.

3. Remaining Laps Are Automatically Calculated – The operation board processes the race information and determines the number of laps remaining.

4. Information Is Sent to Lane Displays – The calculated information is transmitted to the underwater display boards.

5. Swimmers View the Remaining Laps – High-intensity LED displays allow swimmers to easily monitor their remaining distance.
