Compared With Other Models
- WP48 10x50
- The 12x offers higher magnification but is more sensitive to hand shake; the 10x is more stable for handheld use
- WP48 16x50
- The 16x reaches further but gives a dimmer image and is harder to hold steady; the 12x offers a balance between reach and usability
- Waterproof roof models such as the WD67 8x42
- The WP48 is not nitrogen filled and will fog in damp conditions; it is not rated IPX7 and cannot be used in rain or spray
- Porro models with BK7 prisms
- The BAK4 option improves light transmission and edge sharpness, but the BK7 is a lower-cost alternative with similar performance in most conditions
Use Guide
