Greatland Laser Signal Laser

Unlike pyrotechnic flares, which are single-use, flammable, and expire, this laser is reusable and non-hazardous. It provides a consistent, long-range beam that can be used repeatedly without the risk of burns or fire hazards.

Yes, it is designed for both day and night use. While its maximum visibility of 20 miles is achieved at night, the beam is powerful enough to be spotted by search and rescue teams during the day when aimed correctly.

Absolutely. The device features a rugged, waterproof construction that is rated for depths up to 80 feet, making it reliable for marine environments or heavy rain.

The device offers 40 hours of continuous operation on a single CR123 lithium battery. This extended runtime ensures you have plenty of signaling time if you need to maintain a signal over a prolonged period.

Class 3R indicates that the laser is powerful enough to be effective for signaling at long distances but requires standard safety precautions. You should avoid looking directly into the beam or pointing it at people or aircraft.

The laser diode itself is rated for 10,000 hours of life, so it is built to last for many years. The primary maintenance required is simply checking the battery periodically to ensure it is fresh and ready for use.
