This classic design tripod kit, the Adventure TAD18AHD1A, offers advanced features and controls for exploring every style of photography. The Adventure tripod combines aluminum legs with lightweight magnesium castings and quick flip leg locks for ease of use. Included in the kit is a 3-way head with an arca-swiss style plate offering control of 3 axis of movement. This tripod kit includes the new HD1A head.There are two major changes to the overall design of the head. The first is that it now includes an Arca-Swiss compatible plate with our Pull/Twist security feature. Many photographers already own tripod kits with heads that are Arca-Swiss compatible so photographers can swap between Ball Heads and 3-Way Heads without needing to change Qr plates. The second upgrade is that the new design now incorporates 3 bubble levels for precise and accurate positioning. Reference scales have also been added to the HD2A and HD3A models so that settings can be easily replicated. All models offer a side tilt range from -90 deg. / +15 deg. , Front and rear tilt range of -35 deg. / +90 deg. and full 360 deg. rotation. The HD1A can carry a maximum load of 11 lbs / 5kg..
