SVH15 Drag-Control Video Fluid Head SVH15 Drag-Control Video Fluid Headis the most professional one of SIRUI, which is constructed with aluminum alloy. Fully NF blocking hydraulic damping is designed to ensure smoothly operating from -40℃ to 60℃. 7 steps of counterbalanceand the incremental pan and tilt drag-control can balance different camera size and weight, providing ideal and comfortable operation. At present, this kind of fluid head is extremely expensive. However, SIRUI has researched and developed one fluid head with both affordable price and high quality, which is suitable for more users. At present, most fluid heads are designed with damping gear adjusting structure, which can not balance different cameras size and weight, or inverted chip structure, which can not be used at low temperature. To make up for the shortage, fully NF blocking hydraulic damping is designed in SIRUI SVH15 to ensure smoothly operating from -40℃ to 60℃. The incremental pan and tilt drag-control can also balance different camera size and weight. 7 steps of counterbalance can balance different camera weight from 4kg to 15kg, making it universal and flexible. When using equipment of different weight, the stepless pan and tilt drag-control allows locking the head in any position safely. You can also flexibly adjust the position when adding or reducing accessories. In addition, the angle of the head with heavy equipment can easily be adjusted. Stepless Adjustment SIRUI Incremental Stepless Adjustment Gear damping head can not help balance equipment accurately Panning and tilting locking knob are separated. Pull the knob for convenient direction adjustment. 360° panning -70°~+90° Instead of the traditional insert method, side loading is designed on SVH15 head, which means that you can insert equipment from one side both easily and quickly. Even with heavy equipment, it also works well. After side loading, there is a 30mm back and forth range for adjustment, helping shooting with tphoto lens. 30mm back and forth adjustment range after side loading Besides built-in quick release plate, this SVH15 video head is compatible with DJI RS2 / RS3 / RS3 Pro Quick Release Plate, which allows instantly switching camera between stabilizer and tripod.
