Overall this product was a disappointment for the money spent and there was clearly a lack of attention put into human engineering or operational application. It does have good color night vision and functions as described in that regard. The images are also far sharper than any image intensifier based device. While the image quality is good, the night/twilight/day selector is small and difficult to manipulate even without gloves, and the lens adjustment is easily bumped out of position when attempting to adjust the N/T/D switch. This is definitely below par for hunting or tactical use due to the direction arrow controls being so small, making them difficult to manipulate when wearing all but nitrile gloves or perhaps tight fitting pilot’s gloves. Typical Nomex gloves or Mechanix type protective gloves will make this problem worse. It is also a sound and light discipline disaster, due to readily visible green and red LED’s on initial startup, combined with a zingy noise. You shouldn’t have to be an operator to realize this; any hunter or surveillance specialist will pick this out as a problem immediately. This will give away your position day or night so attempting to use this for law enforcement, security, or military surveillance is a mission failure waiting to happen. These should be disabled from the start and require a menu selection to enable them. Another point of failure is loading and unloading the battery. The rear end has to be removed and has no retaining cord, strap, or cable. If you were attempting to change batteries in a moving vehicle or during a high stress situation, this could easily get away from you, possibly putting your NVD out of action. The release lever for the end cap / battery access is also very difficult to operate when you are wearing gloves, probably impossible for someone with big fingers plus gloves. The “instructions” are a flimsy folded piece of paper with tiny printing that is difficult to read in all but bright light conditions. For the amount of money this cost I’m irritated that Sionyx couldn’t provide an instructional CD or mini-disc with a PDF instruction manual, let alone print a proper instruction booklet, even in black and white. I’ve paid less for other NVD’s and IR/visible lasers that come with a paper manual that provides more information in a format that doesn’t require magnifiers to read comfortably. It also wouldn’t have cost the manufacturer too much to throw in one of the Picatinny mounts with the package deal, especially since another manufacturer sells 3 different heights for $1 more. Next time, Sionyx, please do better research and look at some mil-spec gear to avoid the problems inherent to the Aurora not-so-pro.
