I got this for Christmas a few years back, but never really used it much. It is the Explorer Marine series (which is waterproof and floats), and I believe it has 3.1x magnification and is considered a Gen I night vision (don't expect it to look like the night vision off of a video game or the movies, but it works well at reasonable distances). It runs off of one Cr123a Lithium battery, and is in like new condition. It may have around 2 hours of total use on it...the lense cap has never been off in a lighted area, so it still works perfect.
I can't find the box that it came in, or the owners manual...so it is just the monoculer itself (but I'm sure the box is floating around in my basement somewhere, so I may still find it). Back when I got it, they were going for around $300...I'm sure the price has dropped some by now, so I'm looking to get $175 OBO for it. Located in La Salle, MI.
