It clamps onto the objective lens of your PVS-14 or one tube of your PVS-31, and from then on a warm body glows on top of the green or white phosphor picture you already trust: the tube shows you the ground, the ADV-COTI shows you what is alive on it. A 640x512 thermal sensor with a 12 micron pitch, a 35 x 30 degree overlay at 1x, and an optical overlay that needs no calibration after install. Direct price $3,199.95. 640x512 clip-on thermals in this class sell for about $3,577 to $4,475 at US dealers today (read October 2026).\u003c\/p\u003e\n\u003cp\u003eThe ADV-COTI is an add-on for people who already own analog night vision.

The image intensifier tube amplifies light and shows the scene; the ADV-COTI sees heat and lays it over that same picture, so warm bodies stand out even when they are hiding in shadow or brush. It is a thermal imager, not night vision: it reads heat, not light, and it has no eyepiece of its own. It is the partner to your analog tube, not a replacement for it.\u003c\/p\u003e\n\u003ch3\u003eADV-COTI specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eThermal sensor\u003c\/th\u003e\n\u003ctd\u003e640x512, 12 micron pitch, uncooled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens\u003c\/th\u003e\n\u003ctd\u003eF\/1.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMagnification\u003c\/th\u003e\n\u003ctd\u003e1x, matched to a 1x night vision tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverlay field of view\u003c\/th\u003e\n\u003ctd\u003e35 x 30 degrees (horizontal x vertical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRecognition distance\u003c\/th\u003e\n\u003ctd\u003e275 m on a 1.7 x 0.5 m target (manufacturer test figure)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverlay method\u003c\/th\u003e\n\u003ctd\u003eOptical overlay into the night vision objective.

The tube amplifies light and shows the scene; the ADV-COTI sees heat and lays it over that same picture, so warm bodies stand out even when they are hiding in shadow or brush.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I have to calibrate or zero it to my tube?\u003c\/strong\u003e\u003cbr\u003eNo. The overlay is optical, so once the clamp is closed and the unit is on, the heat lines up with the tube image. Targets closer than about 30 m can line up less cleanly, and under 10 m the overlay is not meant to be used.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat thermal sensor does the ADV-COTI use?\u003c\/strong\u003e\u003cbr\u003eA 640x512 sensor with a 12 micron pitch behind an F\/1.0 lens, at 1x so it lines up with a 1x night vision tube.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it fit my Night Operators PVS-14?\u003c\/strong\u003e\u003cbr\u003eYes, with the clamp ring set that ships with every ADV-COTI from us.

You keep both tubes for light and add heat to one eye.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it work on other brands?\u003c\/strong\u003e\u003cbr\u003eThe clamp is built for the PVS-14 and PVS-31 objective family. Because objective sizes differ between makers, email info@nightoperators.com with your model before ordering for anything that is not ours.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it come with a remote?\u003c\/strong\u003e\u003cbr\u003eYes. A wireless 2.4G remote with the same three buttons as the unit (power, mode, plus\/minus) is in the box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the battery last?\u003c\/strong\u003e\u003cbr\u003eAbout 3 hours on one CR123A in the unit, and about 10 hours on the external battery pack, at 22 C. Cold shortens both, as with any lithium cell.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it waterproof?\u003c\/strong\u003e\u003cbr\u003eIt is rated to 1.5 m of water for 30 minutes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I see thermal on its own, without the tube?\u003c\/strong\u003e\u003cbr\u003eNo. The ADV-COTI has no eyepiece of its own; it is made to feed your night vision. For a thermal you can look through on its own, see the PREDATOR.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the ADV-COTI night vision?\u003c\/strong\u003e\u003cbr\u003eNo. It is a thermal imager: it reads heat, not light. It is the partner to your analog tube, not a replacement for it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much does the ADV-COTI cost?\u003c\/strong\u003e\u003cbr\u003e$3,199.95 direct. In a kit with a PVS-14 PRO or PVS-14 STANDARD at any FOM tier, $150 comes off automatically in the cart; with a PVS-31 PRO at any FOM tier, $200 comes off.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it ship outside the USA?\u003c\/strong\u003e\u003cbr\u003eYes.
