The two alternatives we would look at next, with their key figures.



Sensor (12 µm pixels) and lens stated by Burris, NETD 50 mK (the figure we score). With our formula (focal length ÷ pixel pitch, 3 pixels on a 1.8 m target) that gives a computed reach of 1,750 m.
Burris's v3 manual lists a 400×300 VOx sensor with 12 µm pitch, NETD ≤50 mK at F1 and 25 °C, a 35 mm F1.0 lens with manual focus, 1 to 4x digital zoom, a 1280×960 color LCOS, nine palettes and a detection distance of 1,000 m (1,100 yd) on a deer for the BTH35.
Our calculator, which only looks at lens and pixel size, gives about 2,600 m to detect a person and about 365 m (400 yd) to recognize a coyote, the same as the Pulsar Axion 2 models. The 7.8° × 5.9° field is the trade-off: you see far, through a straw.
Battery design is good: two 18650 cells, at least 5 hours at 25 °C by Burris figures, swappable without losing power, plus USB-C. Burris includes Picatinny accessory rails and a 1/4-20 tripod thread.
Sensitivity, size and price. ≤50 mK is the highest NETD figure we list, which costs contrast on humid nights. At 630 g and 9.8 inches it is the third heaviest model here. And the $2,160 MSRP is close to the Pulsar Axion 2 XG35 ($2,499.97), which has a 640 sensor and IPX7.
Water protection is stated as "Waterproof: YES" in the manual without an IP code, and the warranty is 3 years in the US (2 years internationally), per the manual.
Points taken from the official US product page.
Sensitivity: ≤50 mK at F1, 25 °C (Burris BTH v3 manual). Battery: 2 x 18650, at least 5 h at 25 °C (Burris figure), hot-swappable. Photo and video recording.
US price checked on November 9, 2026 at the Burris (MSRP, dealer list): $2,160. Burris lists the MSRP and sends buyers to dealers. The price at the store is the one that applies.
Burris lists the BTH35 v3 at a $2,160 MSRP on its product page (November 9, 2026) and sells through dealers, where prices may be lower. If you like its reach, also look at the Axion 2 XG35 and the Vortex Veil 400.
Pick the Burris BTH35 v3 if reach and swappable power matter more than weight: its 400×300, 12 µm sensor sits behind a long 35 mm F1.0 lens, so it reaches as far as the 640 Pulsars, with two hot-swappable 18650 batteries, Picatinny accessory rails and the BurrisConnect app. It scores 8.4/10, last in our overall list: ≤50 mK, 630 g, no IP code and a $2,160 MSRP.
