When there are long distances to scan a high magnification ocular is just right.
The zoom 7-15x35 Nikon's can identify what is it however they are somewhat bulky.
Leupold's 7/12x32 switch powers are excellent however expensive.
The Hensoldt 8x56 Nacht Dialyt's I got over half a century ago are big, heavy and best in some ways.
Each person should look through all of the optics available and pick what's best for their eyes and search.
