The Magnum-7, from the magnum family, is a rugged 7-function manipulator used primarily in ROV applications. This manipulator is designed to be reliable while operating in harsh environments. Components and assembly make this arm completely field serviceable.

The small stow envelope makes the Magnum-7 ideal for cage deployed vehicles. Typical ROV installations have a Magnum-5 port side and a Magnum-7 starboard side. In this configuration, the Magnum-7 is usually used for precision maneuvers while still being able to lift significant loads. Both port and starboard versions are available.

The dexterity and range of motion of this arm make it ideal for jetting and brushing operations, debris clearance, valve turning and bolt torquing, cable cutting, cable repair, biological and geological sampling, archeological work, transponder and probe installation, salvage and recovery.
