The MK3 ODEO Flare™ (Omni Directional Electrical Optical signal) is an innovative replacement and enhancement to traditional hand flares. 6 hours full power operating life whilst traditional flares illuminate for 30 seconds before extinguishing. Because no pyrotechnics are used, the MK3 is totally safe when switched off, and because it uses battery power it can be safely posted or carried in baggage on flights. Originally designed for marine use, the MK3 works for any outdoor activity as kayaking, mountaineering, skiing, etc. Designed according to SOLAS, the MK3 ODEO Flare™ is a genuine alternative to the pyrotechnic red hand held flare.
