DTD 1431 MkII
DTD 1431 MkII
A dual-tube binocular, and the device most owners settle on. Both eyes look through glass, which restores the depth perception a single tube cannot give you and makes moving over broken ground at night far less tiring.
Each side folds up independently, so you can drop one out of the way when you want an unaided eye for a map, a light or a conversation. The housing takes standard lenses and mounts, and a thermal unit can be added later without replacing anything.
Bring your helmet to the showroom in Villmergen and we will fit it properly, by appointment.

Questions before you buy
Green (P22) or green (P43)?
Both are green, and the difference is the chemistry of the phosphor screen, which sets the tone of the image and how quickly it decays. P22 is the deeper, traditional night vision green with longer persistence, which some people read as a smoother image. P43 is a lighter, slightly yellow-green tone with a narrower output spectrum and a faster decay, so fast movement smears less. Neither is better; it is preference, and the tube behind the screen determines actual performance. Most of our customers choose white (P45), which renders the scene in greyscale and is easier to read over long sessions, so we stock green in the entry tube only. If you want green on a higher tube, ask us and we will source it.
Which tube tier should I choose?
Figure of merit (FOM) is signal-to-noise ratio multiplied by resolution. It ranks tubes on paper, but it does not show noise behaviour, halo or edge sharpness, so a higher tier buys you a cleaner image in less light rather than a different kind of image. The ladder runs GEN2+ NVT4 FOM1400+ AG, GEN2+ NVT5 FOM1600+ AG, GEN2+ NVT6 FOM1800+ AG, GEN2+ NVT7 FOM2000+ AG, GEN3 FOM1800+ and GEN3 FOM2000+. Every tier listed is autogated, so the tube switches its voltage automatically to protect itself and hold contrast when bright light enters the scene, street lamps included.
Why a binocular over a monocular?
Two tubes give depth perception and less eye fatigue over hours. A monocular keeps one eye dark-adapted and travels lighter. The BNVD-1431 MK2 splits the difference: each pod flips independently, so you can drop one pod and keep that eye dark-adapted whenever you want to.
Can I add thermal?
Yes. The pods accept thermal imagers such as the E-COTI and Jerry-C, which gives you thermal fusion for night vision on the housing you already own.
Can you ship outside Switzerland?
Complete devices are controlled items. We deliver to Switzerland, Liechtenstein and EU and Schengen countries. Outside Switzerland and Liechtenstein we need a signed End User Certificate and export clearance before dispatch, and if clearance fails you get a full refund.
Export and delivery
Export and delivery
Night vision and thermal devices ship to Switzerland, Liechtenstein and EU/Schengen countries only. Deliveries outside Switzerland and Liechtenstein require a signed End User Certificate: after payment we send you the certificate, you sign and return it, we complete Swiss export clearance, and your device is dispatched with tracking. If clearance cannot be obtained for your country, the order is refunded in full. Spare parts and accessories are not controlled goods: they ship without a certificate. Collection at the Villmergen showroom, by appointment, is free of charge.
