Short distance scanner
PAS-29/COTI, 10mm 1x 320(30)
PID inside 150yds ... detection ... 500yds ... besides short distance, the main downside of this device is no battery pack. In zero-F weather, i get about 15m max before having to change the battery. Fortunately the battery cap is easily accessible with the device on my head and battery changes with gloved hands can be done. The plus of this device is that if I see critter with the thermal, I can shoot it with the laser ... as the images are aligned.

Medium distance scanner
ATN ODIN, 17mm 1x 320(30)
PID out to 500yds in some conditions ... detection ... out to 1200yds in some conditions ... with IRD ext. battery pack runs on helmet for 1 month plus. Has PVS-14 form factor so runs in dual mount beside 14. Allows critter detection while rolling on 4-wheeler. Main down side is image is not as clear as OASYS core devices. But surprisingly useful, given that it is olde ATN device. I use an olde Aaron amber glass filter screwed on the back to reduce brightness to below headache inducing limits. The glass amber filter is MUCH clearer than the wilcox plastic ones.

Long Distance scanner (no pic yet)
TEO Mk3 60mm 4.5x 640(60) just upgraded my 35mm to 60mm and still getting used to it. Almost useless for coop patrol now (which leaf is that I see !?
) but scanning items 400+ yds away it is good at.

New Medium distance scanner (no pic yet)
I ordered an IR-Patrol ... and a 3x magnifier. I am hoping this will replace the ODIN on my head in 1x mode and the Mk3 35mm on rifle with 3x magnifier for coop patrol ... though 1x unmagnified might work better.
I will switch the ODIN to the .22lr for (semi) permanent rat patrol ... got M-69 mount, but need to carve on it a little. The ODIN is apparently an L-3 housing whereas the M-69 is carson housing compatible..
