Handheld monoculars commonly list objective diameters around 24–25 mm, while the small beginner telescopes in the listings show much larger apertures, for example 70 mm and 220 mm.

Several digital night-vision entries specify a 3W infrared illuminator at 850nm with adjustable output. Stated full-dark visible ranges in the descriptions include figures such as about 150–300 m, 300 m (984 ft), and 350–400 m in specific product details.

Digital monoculars use small built-in screens; common sizes shown in the listings are about 2.7 inches, 2.0 inches, 1.5 inches and 1.4 inches, implemented as HD/TFT/IPS panels depending on the model.
