Crafted from high-grade aircraft aluminum and featuring a durable hard-anodized finish, the Leofoto LH-LSC Ball Head Series for Shooting/Hunting is designed to meet the stringent demands of professional shooting and hunting. 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.
