These aerial alert signals attract attention day or night -- and signal that you are in trouble.
The Coast Guard recommends that you fire two aerial flares, one immediately after the other, so rescuers can confirm the sighting and/or direction of the signal.
This re-engineered signal burns longer and brighter, and goes higher, than the standard 12-gauge signal.
