The Odeo Flare MK3 is the new alternative to the traditional red pyrotechnic hand-held distress flare. It is similar in size to traditional flares, but instead of using dangerous explosives to burn, it uses battery powered light emitting diodes.Traditional flares will burn for around 30 seconds before extinguishing: the Odeo Flare 'burns' for around 5 hours at full illumination. Because no pyrotechnics are used, the Odeo Flare is totally safe when switched off, and because it uses battery power (high power lithium iron-disulphide cells), it can even be safely posted or carried in baggage on flights.Whilst originally designed for marine use, its lightweight, safe performance means that it is incredibly useful for any outdoor activity - Mountaineering,kayaking skiing, expeditions.
