The Classic Heavy is a great choice for extremely heavy loads and precision pointing accuracy. Not affected by wind loads or other outside forces. This unit has amazing low  velocity control and can be used for tracking very low speed objects like celestial objects. Super Slow velocity control down to .004 deg/second and a max velocity up to 60 degrees/second.

With a max velocity of 60 degrees/second target acquisition is fast even with heavy loads. The strength (412 ft lbs torque) of this unit makes it a great choice for large diameter radar dishes or antennas with high wind load.

Very small package size for a Pan/Tilt unit with this much torque.
