Lightweight yet powerful - OZEN's most versatile performer for ENG and EFP applications Counterbalance (10) 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 15/15S enables the operator to quickly alternate between multiple camcorder-configurations of payloads between 4-16kg (8.8-35.2 lbs). Fluid drag AGILE 15/15S features a 7/7 + 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 Interface AGILE 15/15S offers the choice of two industry-standard camera mounting interfaces enable seamless integration with nearly any brand of camera support already in use.AGILE 15 with E-Z LOAD, compatible with the spring-loaded, capture-type camera mounting interface, facilitates fast set-up conducive to 'shoot & scoot' ENG-type use.AGILE 15S with S-LOC delivers greater front-to-rear balance adjustment-range to accommodate exceptionally front-heavy or back-heavy payloads. Ergonomis & Compatibility Experienced operators will appreciate: The familiar ergonomics of incremental pan/tilt fluid drag & counterbalance controls Distinguishable 90 degree-opposed pan & tilt brakes Replaceable pan bar rosettes for longer fluid head usability An illuminated bubble-level and spare camera plate screws, and many other use-friendly features.They' re all located where experienced operators expect, and operate likewise, precluding need to re-train 'muscle-memory'.
