What Makes this set WOW?
Retractable arm with a gripper: A functional, manually controlled manipulator allows for precise lifting of the barrel included in the set, which perfectly imitates collecting samples from the ocean floor.
Triple system of rotating propellers: The model has three independent propulsors which, thanks to integrated gears, rotate during play, imitating the advanced propulsion of real research boats.
Opening Observation Dome: The transparent cockpit element can be lifted to provide access to the detailed interior with pilot seat and control panels, greatly enhancing display.
Integrated Heading Control System: The built-in steering mechanism allows you to actually change the direction of the model, offering young builders a hands-on lesson in engineering and mechanics.
