The latest version of this Odeo electronic flare is an LED device with a number of improvements on the five-year-old Odeo Mk3. The new unit is smaller than its predecessor and adds an infra-red LED signal that can be picked up by rescue vessels and aircraft equipped with night vision devices. Illumination time has been extended by 25% to eight hours and the battery can be replaced by the user. As the Odeo Distress is battery-powered and not a conventional pyrotechnic, transporting the device is not a problem even when flying.
