Half the weight, half the glass, one eye · review
Pankoo's 16x52 monocular: a BAK4 prism, fully multi-coated SMC green lenses, a nitrogen-filled waterproof body and a hand strap, sold for hiking, birdwatching and concerts.
Sixteen times on a 52 mm objective, a BAK4 prism, fully multi-coated SMC green lenses, and a nitrogen-filled waterproof body. Amazon’s item data gives 308 g (10.9 oz).
52 divided by 16 is a 3.3 mm exit pupil: bright in daylight, dim at night. And at 16x, hand tremor is very visible. This is a daytime instrument first.
The listing says SMC coating makes light transmittance up to 99.8%. A single coated surface can approach that; a whole monocular with a dozen surfaces cannot. Read it as a coating claim.
Braced, it shows the Moon’s craters at 16x. For stars and clusters, a 10x50 binocular gathers more light with both eyes.
On November 7, 2026, Amazon.com listed it at about $22 from a third-party seller.

By hand, often. Every tremor is magnified sixteen times. Brace it against a post or your face and shoulder; for long looks, a support helps.
On the Moon, yes. For stars, the 3.3 mm exit pupil delivers less light than a 10x50 binocular's 5 mm.
That figure may describe one coated surface. A whole monocular with many surfaces transmits much less; treat the number as a coating claim.
7.2/ 10
A long-reaching pocket monocular whose exit pupil and steadiness both argue for daytime use.
