Counterbalance(16) increments of adjustable & repeatable counterbalance for fast set-up typical of ENG/EFP-type use. CNC-machined selector-dial mechanism facilitates crisp, repeatable increment-selection. AGILE 20/20S enables the operator to quickly alternate between multiple camcorder-configurations of payloads between 4-28kg (8.8-61.6lbs). Fluid Drag AGILE 20/20S features a 9/9 + 0 fluid drag mechanism, which is incrementally adjustable and repeatable. The smooth, uniform fluid drag neither deviates nor deteriorates over time and usage. The tremendous amount of fluid drag available at higher increments enables an experienced operator to acquire full-zoom pan/tilt-intensive images that are indistinguishable from those acquired in-close. Camera Mounting InterfaceS-LOC delivers greater front-to-rear balance adjustment-range to accommodate exceptionally front-heavy or back-heavy payloads. Ergonomics and Compatibility Experienced operators will appreciate: the familiar ergonomics of
