The DTNVG is not their first original design. You might remember our review of their Lunox monocular that we liked a lot. Obviously, here, the difference is that you get a binocular–one image intensifier per eye that comes in a neat package. There are many similar systems like it, such as PVS-15, PVS-31 or BNVD but DTNVG has a lot to offer.
