Re: Heard of laser flare lights?

I purchased the Greatland laser flare as part of my personal equipment when I sail offshore on OPBs (other people's boats). When I go offshore on an OPB I bring my own PFD, lanyard, PLB, personal AIS beacon and the laser flare. It's not that I don't trust the people I sail with, it's just that I prefer to have my own gear and to know that it's working as it should.

Coast Guard helicopter responding to distress call hit by laser - Hawaii News - Honolulu Star-Advertiser

Coast Guard helicopter responding to distress call hit by laser

By Star-Advertiser staff


POSTED: 04:51 p.m. HST, Nov 26, 2013
LAST UPDATED: 07:01 a.m. HST, Nov 27, 2013




STAR-ADVERTISER ARCHIVE
The Coast Guard said one of its helicopters was hit by a green laser while flying in the vicinity of Waimanalo Bay Saturday.

It's the fifth lasing incident within the last year involving Coast Guard Air Station Barbers Point.

The lased MH-65 Dolphin helicopter crew was conducting a search in response to a distress call when the incident occurred, the Coast Guard said.

Four crewmembers observed the laser sweeping the aircraft and one of the pilots was struck directly.

The Coast Guard is working with the Federal Aviation Administration and the Honolulu Police Department to investigate the incident.

Laser pointers can cause glare, afterimage, flash blindness or temporary loss of night vision.

The Coast Guard said it is a federal crime, as well as violation of most states' laws, to aim a laser pointer at an aircraft. If an individual is caught purposefully lasing an aircraft, punishment ranges from being arrested or having to pay a civil penalty of $11,000 for a single offense, to more than $30,000 if the individual has multiple offenses.

Re: Heard of laser flare lights?

So, if you want to be rescued, don't shine your laser at the helo!!! This guy (from a posting on page 2 of this thread) seems to have shone his off at an angle, away from the rescue helicopter, turning his light into a sort of aero beacon, showing exactly where he was:

Ths Coast Guardsmen involved with his rescue did not seem to mind him having and using a laser.

Re: Heard of laser flare lights?

Are these ones getting pointed at CG helos actual rescue laser flares, or just laser pointers? I'd be interested to find out if they were, and if not, is there a difference between ones designed for rescue use vs a standard one (other than shelf life, waterproofing etc).

Re: Heard of laser flare lights?

I don't think Professor Schmidt's laser pointer has a battery that will last as long, or a beam large enough to really show up in the dark at distances of 20 miles. Haven't tried either, however.

Re: Heard of laser flare lights?

If you follow the link provided in post #17 by knuterikt it answers most of the questions people are posing here.

The signal lasers are different than the pointer lasers. They have a broader beam and are not harmful to pilots because the intensity of the beam is 1/1000th of the pointer variety, but still visible for 20 to 30 miles at night.
