Compared With Other Models
- WD45 6x21
- The 6x offers a wider field of view and better low-light performance but less reach; the 8x gives more magnification but is harder to hold steady
- Waterproof models like WD67 8x42
- The WD45 is not nitrogen filled and not waterproof; it is only daily-life water resistant, so it is cheaper and lighter but not suitable for wet environments
- Porro prism models such as WP48 10x50
- The porro has a larger objective and better light gathering but is bulkier and harder for small hands; the WD45 is compact and designed for children
- Non-waterproof roof models with BK7 prisms
- The WD45 shares the same optical system and build as other non-waterproof roof models; the difference is in size, weight, and target age group

- Close the left eye and turn the right dioptre ring until that side matches
- Fold down the eyecups when wearing glasses and keep them up when not
