Unlimited FOM, Aviation spot spec
Unfilmed ("filmless"), autogated and come with electromagnetic interference (EMI) shielding.
Aviation spot spec is L3Harris' strictest and only permits spots larger than .003" in zone 3 only (please note that all night vision contains small spots to some degree under the countable spot threshold)
FOM = SNR x Center Resolution. See "Spec Key" and "Helpful Info" drop-downs above for more info on specs and spots.

Product Details :
Auto-shutoff flexibility: The DTNVS has a traditional on/off knob but also includes an auto-shutoff feature which engages when it senses that its been flipped up on a helmet, as well as independent pod auto-shutoff when each pod is rotated up.
Independent pod shutoff allows the user to rotate a single pod out of their line of sight (above their eye) which can be helpful when looking through a thermal scope. It may also be helpful if the user wants to use a single monocular (which also saves power). Additionally, by rotating both pods out of the way (as opposed to flipping the device onto the helmet), the user can quickly collapse both pods for fast use without needing to flip the goggle down from the helmet. This creates additional flexibility for moving in and out of tight spaces like vehicles, where the user might otherwise accidentally strike their goggles on a door frame or other object when flipped up.
The auto-shutoff feature is optional can be disabled if the user has a need or preference for "always on" or can't risk an accidental shutoff (fast-roping, climbing a ladder, etc.)
Battery Life: The DTNVS uses a single CR123a battery which provides over 25 hours of run time - about 2x that of similar binocular night vision devices that use a AA battery. While some BNVD's with a AA battery include a battery port for an optional battery pack, the DTNVS does not, as its better on-board battery life didn't necessitate taking up additional space on the goggle for a connection port.
Servicing / Maintenance Flexibility: Compared to proprietary or factory built BNVDs like the PVS-31A, the DTNVS uses PVS-14 style optics. As a result, the DTNVS includes an adjustable diopter to closely tailor the focus to the user's eyes (helpful for those that require corrective lenses). Additionally, it provides more flexibility for servicing the device (ex. replacing a scratched or damaged lens) or upgrading the lenses to a lightweight alternative. Inter-pupillary distance stops may be purchased separately and are easily installed (though the majority of users opt to use the device as-is, without them).
Streamlined approach: The DTNVS uses mx10160 format tubes which have automatic gain (brightness) that have become popular in binos like the RNVG and are used in a variety of other goggles such as the GPNVG, PVS-23, ANVIS 9, and others. Controls are simple and familiar: one knob for OFF->ON->IR.
