Application
Wider View, Easier Scanning
Best for: Versatile observation and broader-area scanning
With 2.6× optical magnification and a 12.5° horizontal field of view, the 35mm model provides a wider view for scanning woodland edges, monitoring property boundaries, and observing wildlife across varied terrain. Its manufacturer-rated detection range is up to 1,800m.
Choose the 35mm if: You prioritize a wider field of view, easier scanning, and flexibility across different observation environments.
Application
Greater Reach, More Detail at a Distance
Best for: Open terrain and longer-distance observation
Featuring 3.7× optical magnification and an 8.8° horizontal field of view, the 50mm model offers a more magnified, focused view. With a manufacturer-rated detection range of up to 2,600m, it is suited to observing distant thermal signatures across open fields and other long sightlines.
Choose the 50mm if: You prioritize higher optical magnification and greater detection reach over a wider field of view.
