The next generation of Electronic Visual Distress Signal Device (eVDSD). 8 hours full power operating life whilst traditional flares illuminate for 30 seconds before extinguishing. Because no pyrotechnics are used, the ODF 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 ODF works for any outdoor activity as kayaking, mountaineering, skiing, etc. The small size and waterproof rating IP68 (50m) also makes it an ideal safety device for divers. Designed according to SOLAS the ODF is a genuine alternative to the pyrotechnic red hand held flare.
