LEGO 8250 Search Sub

8250 Search Sub is a pneumatic TECHNIC set of a submarine. The European version of this set, 8299 Search Sub w/CDROM, included a CD with additional building instructions. The set has one pneumatic cylinder that operates the submarine's arm, allowing it to move and grab. The kit also has an air tank, allowing the cylinder to be operated many times without using the pump. The submarine's cockpit can be opened, allowing the pilot and his 'scooter' to get in and out. The set not only includes a minifigure, but also diving equipment for the figure. The alternate model is also a submarine, albeit with a less standard design.
