The leveling base for Gitzo Systematic Series 3 tripods is an interchangeable accessory component that fits into the tripod"s top casting and allows a camera to be leveled easily, accurately and conveniently without the need for adjusting each leg of the tripod individually. The leveling base tilts 15° in any direction around its large half ball, and the ultra-wide platform gives solid support and high performance. It can be used between a Systematic tripod and the head of your choice (it"s ideal with flat-based fluid heads for video, long-lens photography or spotting scopes), or can mount a camera directly as a heavy-duty, low-profile head substitute under medium- or large-format cameras. The leveling base is fully compatible with Gitzo"s new Systematic tripods, in particular with the range"s safety catch feature.
