The Raonhaje Ego is a compact semi-submarine that will be available October this year. Imagine a boat with a transparent compartment at the bottom which you can go to which gives you a view of everything happening under the water. Note though that unlike normal submarines you can’t submerge to deep levels. This vehicle is powered by a battery that can give you 8 hours cruising time (charge for 9 hours). Just remember to include the time needed for you to go back to the dock, hehe.
