Previously available to government customers only, the ECOTI is a small thermal monocular that clips on to a traditional Inight vision goggle, such as the PVS-14, RNVG, DTNVS, BNVD / PVS-31A, BNVD-1531, TNVC-BNVG-M (Artemis), AN/PVS-31D/F5032 SBNVG/EOTech BINO NV, and GPNVG. While some thermal systems have previously been available commercially, they have typically been a generation behind the latest military systems or with uncertain origin.

The AN/PAS-29B ECOTI is an improvement over the legacy AN/PAS-29A COTI first introduced almost a decade ago by Optics 1. ECOTI has a 640×480, 60Hz sensor (compared to COTI’s 320×240 / 30Hz), and has increased field of view by 50% from 20o to 30o. It provides the user with a high definition, real-time thermal overlay. Users can select between Outline, Patrol, and Full Thermal modes, as well as white and black hot polarities. It also has pre-programmed environmental settings to provide the best possible detection in a multitude of operating environments.

Despite the numerous enhancements in performance and capabilities compared to the legacy COTI, the ECOTI is almost a full two ounces lighter. To lighten the load even more, ECOTI is also available without the internal CR123 battery and powered by the Optics 1 6-Cell GPS-enabled External Battery Pack.

ECOTI has a multitude of applications for law enforcement and civilian customers. The thermal detection capability is useful for SAR operations, fugitive and suspect pursuit, and hunting in thick brush or heavy vegetation. Unlike other weapon-mounted thermal scopes and handheld thermal monoculars, ECOTI allows users to be heads-up and hands-free.

Unlike Image Fusion systems such as the FGE and ENVG-B, the ECOTI is a clip-on thermal overlay with a dedicated power supply. A loss of power or damage to either the night vision goggle or ECOTI does not deadline the entire system; users can use one without the other. They can attach the ECOTI to its Eyepiece Adapter and used as a handheld thermal monocular.  Image Fusion systems have complicated and costly maintenance and repairs, leaving users blind in the night.
