The Manfrotto quick release plate 200PL does exactly what you expect from the product. With the handy screw, the 200PL can be quickly and easily attached to a spotting scope or camera. Due to the anti-rotation pin, the spotting scope or camera does not rotate relative to the coupling plate. The ease with which the camera or scope can then be attached to a tripod and removed again is ingenious. This allows the respective device to be safely transported separately from the tripod.
The only downside is that with the older version, the anti-rotation pin can fall out of the quick release plate over time. This took me 7 years, so it's really negligible. Super quality for a good price. Highly recommended for any nature lover who uses spotting scope or camera.
