Hi, me again, sorry, can you guarantee that if I flash it at a UK or Irish SAR helo that they wont have to turn around and go home?
I realise that lasers have differant power outputs, but if your flashed by one you presumably wont know in advance if the levels are considered safe or not...

On the basis your DSC radio is broadcasting position and if your in the water your PLB is broadcasting on 121.5 which they can DF on ........and the 406 alert has got to Flamouth......

You'd hope they dont take offence at a spot of red light and bugger off home

Its not like the nobbers that target choppers with point lasers ....

I reckon the SAR pilots & crew are some of the most experianced out there,and show bucket fulls of common sense by not just bailing on a tasking as they see a red light where they expect a casualty to be .......

Thanks Peter - well answered - The fact flash of Greatland Laser is also Unique compared to a normal laser pointer - can't confuse both - and all likleness the SAR pilot will not know it was a laser.

I would also add that you will have added this to you CG66 or what you call in in Ireland.

Another interesting fact:

Quote from: Marine Offshore Rescue Advisory Group: Good practice in offshore rescue.

http://www.hse.gov.uk/research/otopdf/2001/oto01040.pdf

Image Intensifiers. The most appropriate form of image intensifier is that used in Night Vision Goggles (NVG). These are already widely used in the armed forces and, if used by those searching for survivors at sea, would, according to the HSE report, significantly increase their chances of detecting and locating survivors at night. They could also provide rescuers with greater freedom of action when actually rescuing survivors.

A limitation of NVG is that bright lights such as flares or searchlights can temporarily blind the equipment. However careful operation can reduce the risk of this happening and, if it does, the search can still be continued with the naked eye until the NVG regain efficiency.

It is expected that the use of NVG would significantly enhance the chances of detecting survivors at night, particularly if they are wearing strobe lights or reflective tape (with the search vessel using a searchlight screened from the NVG).
So carrying traditional flares or shining bright torches will affect your rescuers helicopter if they have night vision (NVG).

Greatland Rescue Laser Flares dont affect NVG and are picked up by NVG

Im aware of helimed choppers being above someone having a heart attack, getting flashed by a laser (not just a red light), and returning home. The casualty died. Wether or not they died because the paramedic onboard couldnt get to the casualty is somethin we will never.
Im aware that some pilots need to have eyes tested after getting flashed by lasers etc, and am asking if spr can guarantee that sar pilots will not be affected by those regulations. (I think Its something to do with the caa but im not certain)

That sounds a bit "...I was talking to a bloke in a pub, who new somebody, whose uncle once read on the internet...."

The only thing I can say is that Greatland Rescue Lasers - have been tested by the UK Military SAR , has had the RNLI using them with Helicopters and I have supplied a coastguard teams, mountain rescue teams with them.

Police Aviation News 18th Feb 2006 – (British Based and was the Reason for selling UK)

http://www.policeaviationnews.com/Ac...February06.pdf Page 13

Greatland Laser of Anchorage, Alaska, has announced that its Rescue Laser Flare® emergency signaling devices are both safe and the most effective product of its type available.

These products can be legally used as a distress signal in an emergency as well as tactical situations.

Rescue Laser devices send a conventional laser beam through a special optic that creates an expanding plane of light instead of a potentially harmful focused dot like a laser pointer making it easier to hit the intended target. Pointed at nearby wall produces a line a foot or so long. Pointed and slowly swept back and forth at a rescuer ten miles away and this same
line expands to 3,600 ft high.

The line cannot miss anything in its path—any portion of the line viewed by rescuers appears as a distant red flash like a red light on a police car distinctly different from other background light.

Was on real rescues a few weeks ago.

Thanks spr im coming round to the idea. Seems there are calculations that can be done to work out if flash blindness is an issue. Would be interesting to see some of those
