Greatland Laser Aviation Rescue Light with Superior Visibility

How far away can the Greatland Aviation Rescue Light be seen?

Under optimal conditions the red laser is visible up to 20 miles away at night and about 3 miles in daylight. That long range lets searching aircraft, boats, or ground rescuers spot your signal from well beyond the reach of a standard flashlight, helping you be located faster in an emergency.

What color is the rescue laser beam and why red?

It projects a bright red beam. Red stands out sharply against sky and terrain and is widely recognized as an emergency signal color, which helps rescuers identify your light as a deliberate distress signal rather than ordinary ground lighting while they are scanning a search area at distance.

What battery does it use and how long does it last?

It runs on a single replaceable 3-volt CR123 lithium battery that delivers up to 40 hours of continuous operation. That far outlasts a pyrotechnic flare, which burns for only seconds, so you can keep signaling across an extended search window without running out of power during a long night.

How much does it weigh and how portable is it?

It weighs just 3 ounces, so it adds almost no bulk to a flight bag, ditch kit, or pilot survival kit. The compact, lightweight design fits easily in a pocket and stays within reach for fast, reliable access during an emergency when every second matters.

Is it waterproof?

Yes. The rugged waterproof construction keeps the device working after rain, immersion, or a water landing. That durability makes it a dependable choice for over-water flights, float operations, and any mission where wet conditions are likely to be encountered while you wait for rescue.

Why can't I see the beam myself when I shine it into the distance?

Laser light is highly directional, so unlike a flashlight cone you usually will not see a visible streak unless the beam crosses your own line of sight or strikes fog, dust, or a reflective surface. This is normal. Aim toward your target and sweep slowly so the light reaches the person you want to signal.

Is it eye safe, and can it blind a pilot?

The device spreads its light rather than holding a concentrated point on a target, and the manufacturer describes it as eye safe at normal signaling distances. It delivers only a brief flash as it crosses someone's vision and is not intended to impair a pilot, unlike a high-power laser pointer.

Is it legal to signal an aircraft with this rescue laser?

Laser emergency signaling devices are designed specifically to send a distress signal to rescuers, unlike ordinary laser pointers. This product is built for that emergency signaling purpose. Use it only in a genuine emergency to summon help and follow current regulations, since rules on aiming any laser at aircraft are strict.

Can I bring it on a flight in carry-on or checked baggage?

It uses a CR123 lithium battery, which travelers may generally pack installed in the unit in either carry-on or checked baggage, while spare lithium batteries must travel in carry-on only. Always confirm current TSA guidance before you fly, since the screening officer makes the final call at the checkpoint.

How does it compare to a traditional flare?

Unlike pyrotechnic flares, this rescue light is non-flammable with no fire hazard, so it has no special storage concern and is safe to carry in a flight bag. It is reusable and can signal for up to 40 hours on one battery, while a flare burns only briefly, making the laser a longer-lasting, safer option.

Does this replace a PLB, EPIRB, or ELT?

No. It is a visual line-of-sight signaling device, not a satellite distress beacon. It complements a PLB, EPIRB, or ELT by helping nearby rescuers pinpoint your exact location once they are already searching the area. Many pilots carry both: the beacon to alert responders and the laser to guide them in.

Who makes it and what is the part number?

It is made by Greatland Laser, LLC, and the manufacturer part number is RLL013-01. Referencing this number helps confirm you are buying the aviation Rescue Laser Light model with the 20-plus mile nighttime range and 40-hour CR123 runtime, rather than another signaling product in the Greatland line.
