The AirMarker R.Four fits easily into any boat kit or watersports equipment. Deployable in a matter of seconds, its bright color and high-altitude hovering ability will enhance your safety equipment anytime you’re exploring the waters. In case of an emergency, this glowing orange inflatable balloon can rise up to 5 meters in the air, while its flight altitude can be adjusted to the water conditions and weather by connecting its line to the AirMarker cover. A carabiner with an elastic band allows AirMarker to be securely attached to any equipment, a pylon, railing, a life jacket, a harness, a surfboard, an inflatable boat or even a canoe. The R.Four is supplied in a waterproof AirMarker Dry Bag . AirMarker R.Four’s solid shell is made of high-quality ABS material. It contains the release unit with 3 exclusive AirMarker helium cylinders, a connecting line made of a high-performance synthetic fiber and a special balloon with a 4-point safety mechanism including reflectors and an integrated light source. The LED requires one-time activation using the on/off switch, after that it switches on automatically at 10 Lx and off at 20 Lx (light duration of 22 hours). Once triggered, the balloon rises up to 5 meters and it clearly and unmistakably signals for up to three days that someone needs help. The AirMarker balloon was developed with an innovative special coating designed to positively influence its radar signature. However, depending on radar system parameters, weather conditions, distance, flight altitude, and dynamics, radar detection may also be reduced. In many situations, however, localization by rescue teams using radar search equipment can still be significantly improved. This adaptive radar signature offers practical benefits – for example, by providing enhanced navigational cues and more precise localization support for search vessels involved in the rescue process. Due to the wide range of external influencing factors, no guarantee can be made regarding reliable radar detection. The «AirMarker» system is based on a trigger unit and a luminous balloon that can rise to a height of up to 5 metres on a resistant high-tech rope. Once in place, it signals visibly, clearly and without any doubt from afar that someone needs help. The robust exterior of the AirMarker R.Four is made of ABS plastic. It includes the trigger unit with special helium cylinders, the connecting line made of a high-performance synthetic fibre and the special balloon with integrated light source.
