Leofoto LH-LR Ball Head rafted from aircraft grade aluminum and hard anodized, it has all of the qualities you would expect from a professional-level head. An over-sized, ergonomic locking knob allows 45-degree tilting in all directions and a 90-degree drop-notch facilitates quick and accurate switching from the horizontal to vertical orientation. A separate tension knob is provided to apply the appropriate pressure that safely corresponds to the weight of your firearm. A third knob loosens and locks the panning base which is laser-engraved with markers every 2.5 degrees from 0 to 360 degrees.
