Great value for the money. - Armasight Sirius SD MG Multi-Purpose NV Monocular

Having used several gen 1 units before, I was expecting much better performance from this unit. I am highly impressed. The ajustable gain works great. Much less fisheye effect than gen 1. Virtually no artifacts or black spots in the viewing area. Well built. The gain control and focus rings are tight at first, but get easier to turn after a while. The diopeter adjustment only goes to about +/-3 though, not 5 as stated. Your eye must be very close to the rubber eyepiece in order to see the image though, as the exit pupil isn't too large. Using the armasight skull crusher mount puts the unit too far at an upward angle to be able to see clearly unless you place the head straps farther up on your head, which makes the whole assembly feel less secure. Will probably get a helmet mount adapter with more adjustments. The built in illuminator is only adequate for inside in total darkness. Not helpfull in either spot or flood mode outside unless you are looking directly in front of you at a map or other arm-length object. Use an external illuminator for better results. For the clarity, ease of use, and brightness, this unit can't be beat for the price. Buy two or even three for the price of a gen 3 unit. You'll still be able to see 85% as well as gen 3 for 1/3 the price. The package contains the device, a battery, and a soft carry case. You must provide your own mounts.
