Preface
Maven Optics has worked very hard at producing quality optics and selling them direct to customers. Their products are built in Wyoming (one of my favorite states) from high quality components sourced from places like Japan. I am not new to Maven’s products, and I’ve been very happy with my experience so far. You can read more about other Maven products I’ve used here. But today we are looking at a more recent product, the Maven M.2 12x50mm Monocular. A compact handheld 12X monocular, basically a handheld spotting scope.
I love optical devices like this one, but my immediate thoughts were whether or not I would want this monocular over binoculars. Or if I would leave my spotter in the truck to carry this instead. Hunters love reducing their loadout weight, so carrying an extra optic might be a big ask. But what if it fits in the palm of your hand?
The Maven Optics M.2 12x50mm Monocular
I eagerly opened the box containing the Maven monocular, and was impressed with the packaging and quality. The monocular came with a soft Maven cinch-bag, as well as front and rear rubber lens covers. It also came with a wrist strap that attaches to the lens body, but can be quickly detached by a clip if needed.
The controls of this thing are as simple as you’d expect. There is an adjustable eyecup at the rear, and a ring around the center of the body to adjust focus. That’s about all there is to it, as this thing was made for looking.

I spend a lot of time in the springtime Rocky Mountains, mainly chasing Rockchucks. I couldn’t think of a better reason to break the little Maven M.2 out, it would be great for glassing up some chucks.
In the Field
On a beautiful spring day, my son and I climbed to the eight-thousand foot peaks near our home. And in the cool breeze we sat in the sunshine, looking for varmints that might be doing the same thing.
In the process I got very comfortable with the M.2. I was impressed with how small it is, and how great the image is when looking through it. Whether we were looking close at 100-yard targets or across a deep canyon, the M.2 provided a great picture. It’s 50mm objective lens is likely responsible for taking in so much of the view.
I was also surprised at how sharp the focus was, and particularly how close you could focus on things. It was also impressive that I could focus on things across my kitchen, as well as across a canyon. I wish I could attach this little monocular to my phone for taking pictures.
The rubberized eyecup is nice, and rotating it you can accommodate your preference from the eye. Both front and rear lens covers are made of that stretchy and sticky rubber texture. This makes them more likely to stay in place. It also made it a little more challenging to put into the cinch-bag. The sticky texture of the rubber doesn’t like to slide against the fabric. Not a big deal, but slightly annoying as I like to keep it inside the bag to keep it clean and dust free.
The small strap loop built into the bottom of the housing is perfect for attaching the sling and lens cover lanyards. The wrist-strap is nice, but not sure I’d use it much. I almost wish they’d have put a small threaded boss in the bottom to allow attachment to a tripod. But I have no problem just setting it comfortably in one of my rifle saddles just as I do with binoculars.
Optical Clarity
I have been quite happy with the optical performance of this unit since I first looked through it. The images are very sharp and detailed, giving excellent observational use. Low light conditions like just before dark or as the sun rises are also seen very well through the Maven M.2. The large objective does a great job compressing the landscape into a smaller high definition package for the eye.
With its 12X, some might feel it is a bit much for a handheld device. As I only plan on using it supported, its almost like having a tiny spotting scope in your pocket. When supported by a tripod or backpack, it allows impressive definition of targets and their surroundings.
Usability
This thing is much smaller than I anticipated, which is great news. You wont believe this, but it just like having… half a binocular…
It fits great in the pockets, and is easily used single handedly while your other hand holds a gun or tree branch. The real question when it comes to usability is whether you want to carry the M.2 monocular AND a pair of binoculars, or the M.2 monocular OR a pair of binoculars. It seems not only superfluous to have both, and perhaps even a bit gaudy if you throw a rangefinder into the mix as well.
Durability
As with other Maven products I own, this M.2 Monocular is very well built. Everything is tight and tucked neatly together, I have every expectation that this optic would last for years. There is very little to wrong with it, so unless it gets dropped or run over I don’t see how it might otherwsie fail. And even if it did, Maven has a great unconditional lifetime warranty.
Value
Looking for comparable monocular choices, I found very little that is even close. There is a wide variety of monoculars for significantly less money than the M.2, but they don’t look to be anywhere near the same class either. Most other monoculars that cost more are thermal monoculars that cost thousands not hundreds.
That said, I think you really need to want this monocular in order to justify it. For around the same price you can get a similar pair of binoculars from Maven. Unless you are a one-eyed pirate, there must be a good reason to want the monocular configuration.
Pros and Cons
One reason you might want a monocular is because they are lighter than binoculars. This unit is surprisingly light for what you get from it. If I was on a very remote hunt where every ounce mattered, the lightweight of this unit would be appealing. Its amazing views would be very helpful for both identifying and evaluating trophy animals. As well as general observation. The controls are tight and feel very smooth.
The only downside I can think of is that if you already have comparable binoculars then you probably dont need this. In my opinion it would be an excellent optic to keep handy, unless you already have a pair of binoculars for the same purpose. This does fit easily in the glove box of the truck, giving me an always available high quality optic for observing.
Last Thoughts
Whether you use this as your main spotting optic, or like me, as a capricious indulgence, the Maven M.2 is a very nice addition to your kit. Its quality build and excellent imagery make it suitable for just about anything you need to look at.
