COMPUTERIZED MOUNT FEATURES
All-new design. Sturdier and more rigid with quicker dampening time
Increased load capacity to 55 lbs.
Improved motors provide more torque, better slewing and tracking under heavy loads
Heavy Duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads
The spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh
Internal cabling for worry-free remote operation. Power input and accessory ports remain stationary while the mount slews to avoid snags
Internal hard stops for both axes prevents cable tension and tripod strike
Internal optical sensors on both axes for simple and safe remote operation
Home sensors allow the mount to always start in the index position regardless of orientation before a power reset
Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe
