The PRO AL-523SVH-520 Kit consists of the PRO AL-523 Aluminum legs and the SVH-520 Oil Fluid Video Head. This combination of legs and head make for a great video or stills set up. The PRO AL-523 tripod stands out for its remarkable stability and functionality. Its design focuses on enhancing torsion strength and minimizing vibration through the implementation of a new collar and leg-joint system. This innovative feature enables the utilization of Slik's exclusive Rapid Flip Mechanism (R.F.M.), ensuring effortless and swift adjustment of leg-angles with just one hand, offering three secure positions for stability. Crafted from durable aluminum, the tripod's legs are composed of three sections that can be rapidly deployed and securely locked using user-friendly lever locks, accommodating smooth operation even while wearing gloves. Despite its sturdy construction, the AL-523 tripod remains lightweight, weighing just 3.8 lbs. (1710 g), while impressively supporting up to 13.2 lbs. (6 kg) of weight. When folded, the tripod reaches a compact size of 23 inches, while extending to a maximum height of 62.1 inches. The center column has 4 important features: The thread post is reversible so it can be set to 3/8” or ¼ 20” male threads allowing it to work with any type of head without the need for an adapter. It takes less than 2 minutes to change and all tools and instructions are included with the tripod. The column can be separated into two sections by simply unscrewing the bottom section. This helps reduce weight when needed but more importantly allows you to set the tripod to the lowest possible position off the ground. The column can be reversed so the head can be positioned between the legs instead of on top. This lets you position the camera very close to the ground or provide a straight down view of your subject. Integrated, retractable hook at the bottom of the center column to hang your camera bag for increased stability on uneven terrain or windy conditions. The SVH-520 Fluid Video Head is lightweight and ergonomic weighing only 1.2lbs. Supporting up to 8.8lbs of gear this head is made for video creators, but does not exclude still photographers looking to use it as well. This head offers a fluid pan and tilt movement and is equipped with individual locking mechanisms. The angled pan handle can be positioned for left or right-hand control and rotated a full 360-degrees so the handle's angle is in the best position for any situation. The handle can also be removed to save space. Not to be excluded, the fluid pan and tilt movements make this head great for those using spotting scopes and binoculars. The head uses the SLIK quick release system for easy mounting and removal from your camera. The QR plate uses a folding wing-nut to rotate the standard 1/4-20 thread post onto the camera so no tool is need to attach or detach from your camera. Straight out of the box you will have options for 3/8-16 or 1/4-20 mounting points to screw onto your tripod. The 1/4-20 option will require a simple screw in adapter.
