Features:

• The most striking feature of the DTG-18N is the presence of four separate image intensifier tubes with four separate objective lenses arrayed in a panoramic orientation and can provide the operator more information.
• The operator sees the two center tubes somewhat overlapping the two outer tubes to produce an unprecedented 120° FOV. This is an absolute game-changer for the SOF community.
• They can also be easily removed and operated as independent handheld viewers. The IPD of the two system can be adjusted on the helmet mount.
• The DTG-18N is not only powered by a battery on the device, but also by a remote battery packs, tethered to the unit via a standard DC cable. It comes with a pack that accepts four 3-Volt CR123A batteries that tend to power the unit for 50-80 hours (IR off).
