This amphibious sub-surface watercraft provides both above and underwater viewing options. It’s ideal for exploring underwater environments without the need for a fully submersible craft, because this watercraft’s buoyant above-water upper hull and two-person cockpit provides 180° surface views. The inverted 1 1/2″-thick acrylic hemisphere below provides seating for an additional two passengers underwater views. The two horizontally oriented underwater thrusters are controlled upstairs, and provide up to 6 knots forward/4 knots backward movement as well as 360° turns. On land, each of the craft’s ground track systems are driven by dedicated 48-volt intercooled electric motors, enabling their heavy-duty rubber tracks to climb 30° gradients for easy ocean, lake, or boat ramp-based water entry and egress. Two 24-volt lithium battery packs provide up to 110-hours of water operation and 8-hours on land. Click here to view the first image in today’s viral picture gallery.
