Slik PRO CF-933 Carbon Fiber LegsThe Slik PRO CF 933 Carbon Fiber Legs provide a tall and sturdy base for spotting scopes and digiscoping. With a maximum height of 80. 3" and a maximum load of 22 lbs. the CF 993 is capable of handling anything a birder might want to carry into the field. Its large diameter legs dampen vibrations from wind and mirror slap, and it's tall enough to do astronomy with a straight scope. Yet, at 5. 38 lbs, it's light enough to carry around all day.
