Who the Techno-Stabi TS12x28WP suits
The 16.5 mm eye relief suits eyeglass wearers, and the 11.5 ft close focus helps with nearby subjects. At 17.1 oz it is the lightest stabilized model here, easy to carry on a long day.
A 28 mm objective gives a calculated exit pupil of 2.3 mm, so the view dims sooner than on the 40 mm models once daylight fades.
