Good spotting scopes are expensive and deserve a good stand to hold them steady and secure. The scope mounts to the stand with a standard ¼-20 threaded stud. If your scope does not have this female threaded hole you need the SDI Model 400 which has a saddle mount. The base legs of this stand reach out to 24 inches between ground contact points for great stability. It adjusts to hold your scope from as low as 8 inches to as high as 70 inches from the ground yet it collapses to a compact 18 inches high and weighs only 4 pounds for easy transportation. No plain steel parts to rust – no castings to break. Only anodized aluminum parts with stainless steel and engineering plastic fasteners. No loose mast sections to get lost or rattle around in your bag. Swing the scope for lateral adjustment by loosening the top clamp screw and adjust for elevation by loosening the scope mount knob. This spotting scope stand provides high quality at a fair price.
