What the numbers mean

Both brands are better known for riflescopes and binoculars, and both chose a 400×300 sensor with 12 µm pixels for their handhelds. The lens makes the difference: 25 mm and an 11° field on the Veil, 35 mm and 7.8° on the BTH35. By our formula, that is 1,250 m of reach against 1,750 m.

Day to day, the Veil is lighter (13.3 oz against 22 oz), has a 1024×768 OLED against a 1280×960 LCOS and comes with a lifetime warranty that Vortex says includes electronics. The Burris has two hot-swappable batteries (at least 5 hours) against 4.5 hours per battery for the Veil. Burris publishes a ≤50 mK NETD; Vortex publishes none. Both sell through dealers.
