No seller description or customer reviews are attached to this listing, and the weight figure in the raw data looks inconsistent with a handheld optic, so it has been left out here rather than repeated as fact.

Performance notes
The 85mm objective lens is on the larger end for spotting scopes, which generally improves light gathering and image detail at high magnification and in dim conditions. Manual focus gives direct control over sharpness but takes practice to use quickly on moving subjects.
