We have seen plenty of exciting drones in the past few months. They are great for folks interested in pursuing aerial photography. But most drones are not designed to move underwater. The Mariner is different. This cool drone floats on the water and can take off from the water. It is submersible, capable of moving underwater without getting damaged.
The Mariner can be used to inspect your boat, the keel, rudder, and everything else more conveniently. You can find out more about it on AmbientRealLife.com.
