Your means of travel must be an underwater device capable of descending to very low depths of the sea (Nautile, Mir II, and Alvin). For example, you can take the Nautile, designed for observation and activities at depths of 6,000 meters. Eight meters long, it can fit a team of three people. The Nautile is made of a titanium alloy, has three portholes measuring 120 mm and 16 cm in width, moves at 1.7 knots, can function at 7.5 km below the surface, and has power for five hours. It takes two hours for it to reach 3,780 meters where the Titanic lies.

Two arms and a clamp

At this depth, darkness is complete. The pilot must turn on spotlights and a motor, powered by batteries, which lets the appendages move above the seabed in a lighted area measuring a few square meters. Your only means of direct observation is three portholes that provide a wide-angle view through the use of six spotlights, combining visual range and colour rendering.

You arrive! Before you unfold mysteries lying in the abyss, beyond reality. You can recover objects using two robust and precise robotic arms that can be equipped with clamps for large objects or suction cups for more delicate materials. The objects must be placed into a basket attached to the front of the submarine.
