Compared With Other Models
- WP48 10x50
- The 10x reaches further but shakes more hand-held and gives a dimmer image at dusk; the 7x is better for steady low-light viewing
- Non-waterproof roof models such as the SRB03 10x42
- The SRB03 is daily-life water resistant with BK7 prisms and costs less; it is not nitrogen filled and will fog in a real downpour
- Waterproof models such as the WD67 8x42
- The WD67 is nitrogen filled and IPX7 rated; the WP48 is not and must not be submerged
- Porro models with BAK4 prisms
- BAK4 improves image brightness and edge sharpness, but the WP48 with BK7 is a lower-cost option for non-waterproof use
Use Guide
- Porro Binoculars WP48 7x50 Green: Set the barrel spacing until the two images merge into one circle
- Close the right eye and focus the centre wheel until the left image is sharp
- Close the left eye and turn the right dioptre ring until that side matches
- Fold down the eyecups when wearing glasses and leave them up when not
- Mount on a tripod through an adapter for observation sessions longer than a few minutes
- Wipe the lenses with a soft cloth after exposure to dust or light rain
