This is the point and shoot PT785-S pan and tilt system.  This precision, closed-loop system is designed to manipulate cameras and devices up to 6 lbs even though the entire head weighs a mere 1.85lbs. Each axis is driven by a Hitec HS-785HB servo that is geared down for more power and precision. 1” diameter hollow aluminum shafts supported by ABEC-5 precision ball bearings allow video and power wires to be cleanly routed through the points of rotation and remain tangle free.  The framework is constructed of black anodized 6061 T6 aluminum to create a sleek and robust structure. The stock Hitec HS-785HB servos that drive the pan and tilt can rotate several turns in factory form. By coupling the servo to an external gear set, the amount of rotation is decreased by the ratio but the torque and precision is increased by the ratio. In order to tailor your pan and tilt system to the controller you wish to use, we offer a 3.8:1 ratio as well as a 7:1 ratio. Which ratio do I need?
This system is a simple plug and play with any servo controller.  Perfect for still photography, amateur videography, security applications or even antenna tracking stations.  The PT785-S can easily be mounted to various jib-cranes in the hanging or upright position using the JM-1100 jib mounting kit (sold separately).  Balancing your camera or device is easy using the vertical slide adjustment.  Controller, power supply, and servo extension leads sold separately.  Manufactured in the USA.  Cameras shown in below images are not included.  Patented.
