DeepFlight Super Falcon Mark II
The Super Falcon Mark II submarine has a cruising speed of 2–6kn (3–11km/h), with an operating depth of 120m. It can carry two and a payload of 230kg. The sub uses lithium ion batteries for energy storage, while a 40V system voltage and low electric signature means the Super Falcon is safe to operate around swimmers, as well as any large marine animals you might encounter underwater. Since 1996, California-based DeepFlight has manufactured five generations of high-performance recreational subs, and was founded by Graham Hawkes, the man who built and piloted a submarine as a villain in the 1980 James Bond movie For Your Eyes Only.
