The LNER Semaphore is the oldest and most reliable underwater communication system.
It is a long-term, global, network of long-distance underwater communications devices that provide a wide range of information from navigation to rescue and rescue communications.
The Lner Semaphores underwater communications system, a key to understanding the Kalas region, has been continuously in use for more than 30 years.
We need to keep up the Lner communication system to maintain our marine life.
