Reviews & Ratings for SiOnyx Aurora Pro 1-3x16mm Explorer Night Vision Monocular — 1 review — Page 1

This thing is pretty cool.

It's pretty shocking how much better it can see in semi-dark areas compared to the human eye, especially if there is a bit of ambient IR light around.

You can't use this to walk around at night. Maybe you could drive with it if you mounted it on the front of a car or boat.

However, as a semi-dark camera, video recorder, and stationary observation scope, it works great. (But where's the lens cap? Really, folks...)

It turns out that the included 32-GB SD card only works for files up to 4 GB, which is only big enough for 2 hour videos at some of the lower settings (24 fps, 360p). This is because of the Fat32 format on the card.

AND... if you try to reformat it to exFAT yourself, to support larger files, the Aurora won't recognize the card and demands to reformat it (which it does, back to Fat32). I tried formatting the 32-GB card to exFAT on both Windows and Linux, and the Aurora refused to read the card.

I've now purchased a 64-GB SD card, and that came with exFAT, which *is* recognized by the Aurora.

Even more strangely, if I reformat the 64-GB SD card with exFAT using Window...
