FREQUENTLY ASKED QUESTIONS
While all three products have the same signaling capacity, they do vary in signaling time and design. Please see below.

No. In order to signal at a distance with a laser pointer, you would have to accurately hit your target in the eye in order for them to see you. Our products draw a line which fans out the further it goes. At 16 miles, you have a 6000 ft. long fan of light with which to hit your target. Please see How Rescue Laser Flares® Work
Yes. Our lasers are classified by the The United States Food and Drug Administration as a Class IIIA Laser Product. Just like any other light, however, it isn't advisable to point it directly in the eye at short range for an extended period of time.
No. When the fan of light crosses your target's vision it will appear as a brilliant flash in the distance and will in no way impair their night vision.
However, because the light from the laser pointer remains in a relatively small one-dimensional pencil thin beam, the laser beam spot size at the aircraft is about 240CM (8 ft) in diameter. Because all of this light is concentrated in a relatively small spot, rather than spread out in a long line like the Rescue Laser, the power density impinging on the pilot’s eye is about 1,000 times greater from the laser pointer, at this distance.
Therefore, although the signaling capability of the Rescue Laser emergency rescue and signaling device remains effective for signaling SAR aircraft, the power levels (brightness) of the Rescue Laser is reduced by one thousand times, this is a level where visual flight acuity is not affected.
It should be noted that even the laser pointer’s output although bright, is still about ten thousand times lower than the power level where eye injury can occur, at this distance.
The laser light power density from the laser pointer is 1,000 times higher than that from the Laser Flare, when both measured at 1.5 miles. Neither are remotely a hazard for actual eye injury.
Lasers are directional lights. Unless the fan of light produced by Rescue Laser Flares crosses your line of vision or you pass over a retoreflective material, you will not see the light when aiming at a distance. Please see How Rescue Laser Flares Work
If you were to just hold the laser without aiming while slowly moving it back and forth you will probably not be visible to your target. Because lasers are directional lights, the fan of light must cross their line of vision. This is accomplished by first aiming at your target and then moving the laser slowly back and forth. Every time the fan of light crosses their vision they will see a brilliant red flash. Please see How Rescue Laser Flares® Work
Yes, it does matter. The 6000 ft. high fan of light produced at 16 miles gives to the greatest signaling area. The laser line should be pointed vertically at your target. In order to tell which way the line is directed, point the laser a few feet in front of you on the ground. Please see How Rescue Laser Flares® Work
