The Nikon PROSTAFF P7 8x30 is a central-focus binocular with 8x magnification and a 30 mm objective. It has an 8.7 degree angular field of view, about 152 m at 1,000 m, which helps when you are following a moving boat or bird. Minimum focusing distance is 2.5 m (8.2 ft), eye relief is 15.4 mm, and exit pupil is 3.75 mm. It weighs 485 g (17.1 oz). The body is fibreglass-reinforced polycarbonate resin. It is sealed with O-rings and filled with nitrogen gas, so it is fog-free, and it is rated waterproof to 1 m (3.3 ft) for 10 minutes. That covers rain and spray on deck, but not being dropped over the side and left there.
Our take
This suits casual daylight viewing from a boat, and the 15.4 mm eye relief should work for people who wear glasses. The sealed, nitrogen-filled body copes with rain and damp. The limit is light: a 3.75 mm exit pupil from a 30 mm objective gathers less than 42 mm glasses, so we would not pick it for dusk or long low-light watches. It is also not for submersion.
From our buying guide
Steiner calls 7x the marine standard. Higher magnification narrows the field of view and makes the image more sensitive to hand shake.
Check before you buy:
- The water rating comes with its depth and time, since ratings vary widely between makers.
- The maker says what floats, the body or only a strap, since some make no flotation claim at all.
- A stabilised pair has a water rating you're happy with, since not every one carries a waterproof rating.
