DTD Jerry 31
DTD Jerry 31
A binocular for people who want both eyes working without carrying the weight that usually comes with it. At 480 grams without a battery, it is one of the lighter dual-tube devices you can buy, and it sits unusually close to the face, which keeps your head profile low and the leverage off your neck.
The eye pods articulate, so you can set them to your face properly rather than living with someone else's idea of the right spacing. An infrared illuminator is built in for close work.
Bring your helmet to Villmergen and we will fit it, by appointment.

Questions before you buy
Why choose this over the PVS-31 or the 1431?
The Jerry 31 is our budget binocular. It carries a fixed, manually gated tube set rather than a choice of autogated tubes, which is what keeps the price down. The protection is there, you set it yourself instead of the tube adapting on its own. It is also lighter and lower in profile than most dual-tube devices, which some people prefer regardless of price.
What does manual gating mean in practice?
The tube is gated, but you set the gating yourself instead of the tube switching its voltage automatically as the scene changes. In genuinely dark conditions you will not notice the difference. Where light levels change quickly, an autogated tube adapts without you having to do anything.
Why does the low profile matter?
The device sits closer to your face, so there is less weight hanging forward off your helmet. Over several hours that is the difference between comfortable and sore.
Can I try it before I buy?
Yes. The showroom in Villmergen has a dark room for side-by-side comparison, by appointment.
Can I pay in instalments?
Yes. We run our own instalment plans in-house for customers resident in Switzerland: at least 50 per cent down, the balance split to suit you, and a modest interest rate. Ask us and we will put together an offer.
Do you ship outside Switzerland?
Yes. We deliver to Switzerland, Liechtenstein and the EU and Schengen countries. Deliveries outside Switzerland and Liechtenstein need a signed End User Certificate; we send it after payment, complete the export clearance and dispatch with tracking.
Is bright light a risk for this device?
Yes, more than for our autogated devices: the gating is manual, so nothing steps in by itself when strong light hits the screen. Power it on only in darkness, cap it when in doubt, and treat street lamps, headlights and daylight with respect. Damage caused by exposing the tube to bright light in breach of the operating instructions is not covered by the warranty.
Export and delivery
