As UK Greatland Importer , I tell folk that LED Strobes & Laser Flares are good for guiding rescuers to you position after you alert by other means - VHF , PLB or dare I say mobile phone.
Greatland Rescue Laser & Lights have the advantage of long range - most LEDstrobes / lifejacket lights have range 3nm
even the £12 Guardian LED light has range of 5km.
Is my online store
is my Greatland Rescue Laser site.
I could add 0deo to my website but I choose not to to sell it. make sure if you choose this you buy the MK3...
I currently just about to add MOB exposure torch to website but not cheap £180 ish.
Fenix & lenser torches are good cheaper alternative - with built in SOS program
