The Vortex Triumph HD is a compact 10x28 binocular from Vortex Optics, model TRI-1028. It weighs 12.8 oz (about 363 g) and stands 5.0 in tall and 4.8 in wide. A single centre focus wheel moves both barrels together, and the right eyepiece has a diopter adjustment to match your eyes. The field of view is 279 ft at 1,000 yds (about 93 m at 1,000 m), or 5.2 degrees. Eye relief is 15 mm, close focus is 9.9 ft, and the interpupillary distance range is 56 to 73 mm. The body is nitrogen purged, and Vortex states it is waterproof and fogproof, though it gives no depth or duration rating. A neck strap is included, and the maker backs it with a lifetime warranty.
Our take
This suits a sailor who wants a small pair to keep in the cockpit for day trips, travel and casual watching from a boat. Skip it if low-light brightness matters, since the 28 mm objectives give a darker image than 50 mm glass, especially in the evening. It has no image stabilisation, so expect 10x to shake on a moving boat, and a reviewer notes visible edge distortion.
