The H3-X Rescues at amazing speeds and remote operation features puts itself ahead of the game.

Recently we have improved the Award-Winning Hover Ark H3, H3-R, and the new model is called the H3-X, a 911 series product. Now with a hardened shell, reverse mode, navigation lights, and a few optional extras. This self-propelled, GPS remote-controlled robotic water rescue device is designed for use in marine and water environments where speed is critical to recovering any drowning casualty quickly, safely, and in any water conditions when the risk to personnel may be high when achieving a Rescue. At its core, the device has dual powerful motors, that keep it moving towards its target quickly, even if flipped over by waves.


No need to jump into the water for rescue operations anymore.  Simply throw the water robot into the water, and stand on the shore or a boat, and use the remote control to navigate the water rescue robot to the victim. The battery levels for both the water robot and the remote control are displayed on the LED display screen for the operator. The ability to control the device with simple remote control and a one-touch return home button are welcome additions for worldwide water rescue personnel, empowers responders to manoeuvre in any situation with simple and unparalleled control.



When reducing water casualties, speed is critical. The H3 can reach the victim’s side at impressive top speeds of up to 20 km/h(12.4 mph) or 4 – 6m/second and returning to the rescuer with the loaded victim/s at 2m/s. This is twice quicker than human rescuing and reduces the risks involved for the rescuer. The Hover Ark Rescues amazing speeds and remote operation features put itself ahead of the game.

Payload up to 200 kg

The Hover ark H3-X can Carry a 200 kg minimum payload, it can transport 2 to 4 people or a total of 200 – 240 kg back to shore. The H3-X Rescue device can remotely operate up to an impressive minimum 800-meter Plus (Line of sight) Radio controlled GPS Range.

Against wind & waves

The Hover Ark H3-X will reach the drowning person quickly with a powerful ability to fight through wind and waves. It operates even should it be flipped over by the waves. Remotely operated by rescue personnel from a position of safety either onshore or on another vessel the device reaches the victim and the drowning person grasps the hand belt or center bar, then the operator will control the H3-X to a safety zone either manually or by auto-return. Reverse mode now introduced and automatic return makes it very simple for the device to return to safety. To add to this the device can be thrown safely from a height of 20 meters into the water.

Automatic Return

By using the automatic return function, the Hover Ark H3 will always make sure it can return to the user safely whenever communication signal is lost for over 15 seconds, or simply use the one-key return function to return your victim/s to the location of the operator.
