The Nikon PROSTAFF P7 8x30 (model 16770) is a binocular with 8x magnification and a 30 mm objective lens. It weighs 17.1 oz (485 g), a compact body for carrying on deck. The field of view is 456 ft at 1,000 yards (152 m at 1,000 m). That is a wide view, which helps when scanning for marks or tracking a moving subject. Nikon rates it waterproof up to 1 m (3.3 ft) for 10 minutes. The body is sealed with O-rings and filled with nitrogen gas to keep it fog-free, which matters when you go between a warm cabin and a cold deck. Focus is central only, so there is no separate adjustment for each eye.
Our take
This suits a sailor who wants a light, wide-field 8x for scanning the horizon and picking out marks, and who will keep it on a lanyard. Do not buy it expecting it to survive going overboard: the waterproofing is only 1 m for 10 minutes, and floating is not claimed. Central focus alone also means no separate setting for each eye.
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.
