If you're simply getting into night vision, you've possibly realized that selecting a j arm and rhino mount is the nearly all common starting stage for a cause. It's the traditional setup that provides seen countless hrs of use in both military and civilian circles. While there are certainly fancier, more expensive options hitting the particular market every yr, this specific combo remains the "old reliable" for anybody running a PVS-14. It's rugged, relatively inexpensive, and once a person understand its quirks, it has got the job done with no lot of unnecessary fuss.
The beauty of this set up lies in its simplicity. You possess a helmet, the shroud, the mount, and the arm that holds your monocular. When you've ever actually attempted to walk with the woods with several thousand dollars of optical technologies hanging off your own forehead, you understand that "simple" doesn't always mean "perfect. " There's the bit of an art for you to get almost everything dialed in therefore you aren't fighting your gear all night.
Why the Rhino Mount Still Holds Up
The "Rhino" mount—officially the Norotos Titanium Fixed Front Bracket or maybe the older swing-arm versions—earned its name due to the distinct user profile. When it's turned up, it looks a little like the rhinoceros horn. It's been the standard-issue piece of kit for the US ALL military for years. The reason it's still around is that it's built just like a tank. It's designed to be bumped, dropped, and dragged with the mud while keeping your NVGs attached to your head.
One of the best things about the rhino mount is the "force-to-overcome" mechanism. You don't have to faff around with tiny buttons when a person want to proceed the goggles out there of your line of sight. You simply push the unit up, and this clicks into place. When you need it back, you pull it lower. In a high-stress situation or actually just when you're tired and walking in the dark, that tactile, mechanical simplicity is a godsend. You aren't hunting for the release lever with numb fingers or even thick gloves.
However, the rhino mount isn't without its downsides. Many of these models work with a "bayonet" or "horn" interface. This is the socket where the j arm snaps in. Because these parts are often mass-produced or sourced from surplus, the tolerances may be a small loose. If you've ever felt your NVGs "wobble" or even rattle while you're walking, you're experiencing the classic rhino mount shake. It's annoying, but it's something almost everybody works with eventually.
The Role of the J Arm
The j arm is the literal bridge between vision and the mount. It's a curled piece of plastic material (and sometimes metal) that screws to the threaded hole on your own PVS-14 and after that snaps into the particular rhino mount. It's called a j arm because, properly, it's shaped such as the letter J.
What makes the j arm so important is its ability to swing. Since the PVS-14 is the monocular, you need to choose which eye you need to use. Most individuals possess a dominant attention, but sometimes you need to switch things up in order to avoid eye fatigue or to make use of a handheld thermal with the other eye. The j arm enables you to "clock" the optic, swinging it from your left side to the right side by loosening a browse screw.
This also contains the permanent magnet switch that informs your PVS-14 to shut off when you flip the mount up. This can be a battery-saving feature that furthermore keeps you from accidentally "glowing" in the dark. When you've ever seen a faint green glow coming through someone's helmet whenever their goggles are usually flipped up, it's because their j arm isn't interacting right using the mount, or the sensor is misaligned. Once the j arm and rhino mount work together correctly, that auto-shutoff is the seamless part associated with the experience.
Fixing the Notorious Wobble
In case you spend enough period on gear community forums, you'll see people going on about the "rattle" of a j arm and rhino mount combo. Because these are mechanical interfaces with moving parts, they tend to develop a bit associated with play over time. If you're running or even even just walking briskly, that little bit of movement can feel like your goggles are jumping everywhere.
The good news is definitely that you simply don't need a degree within engineering to solve this. Most guys use what we contact "the bungee technique. " Most modern helmets come with two bungee cords attached to the particular shroud. You connect these onto the PVS-14 or the particular j arm itself. This creates continuous tension, pulling the particular mount back towards the face and eliminating virtually all the move.
In the event that your helmet doesn't have bungees, a little bit associated with electrical tape or even even some thin adhesive-backed Velcro around the "horn" of the j arm may tense up the fit in the rhino mount socket. It's a low-tech solution with regard to a high-tech item of gear, but it works wonders. You need that connection to feel solid, like it's a part of the head protection, rather than something dangling off this.
Adjusting intended for the Perfect See
One of the biggest mistakes newcomers make with a j arm and rhino mount is not spending plenty of time on the particular initial adjustment. A person have three main points of movement: up and down (up and down), tilt (the angle of the optic), and eye reduction (how close this is to your own face).
The rhino mount generally has a slider for eye alleviation. You would like the PVS-14 close enough that you get a full "circle" of vision without your sexy eyelashes hitting the lens. If it's as well far away, this feels like you're looking through the soda straw. When it's too close, the lens may fog up from the heat of your face.
The point is arguably the most crucial. If the angle is off, you'll find yourself craning your neck in odd ways to see clearly. You want the optic to be perfectly parallel to your line of sight. The j arm and rhino mount allow for these micro-adjustments, however you have to be affected individual. I suggest setting up it up in the daytime (with the pinhole cap on, obviously) so you can see what you're doing before you're out within the message black.
Bayonet vs. Dovetail
You might listen to people talking regarding "upgrading" to a dovetail system. While dovetail mounts are generally more safe and have much less wobble, they also require a different type of arm and mount completely. The bayonet-style j arm and rhino mount are the particular standard for the cause: they are all-pervasive.
In the event that you're on a budget or simply beginning out, the bayonet system is properly fine. You can find excess rhino mounts regarding a fraction associated with the cost of the high-end dovetail mount. And honestly, with regard to 90% of users—whether you're hunting hogs, doing stargazing, or just practicing movements—the bayonet setup is more than enough. It's the "Mil-Spec" standard, and while Mil-Spec isn't always the "best, " it really is consistently "good more than enough. "
Sustaining Your Gear
Since the j arm and rhino mount are mechanised, they actually need a little love today and then. The particular thumb screw on the j arm can work by itself loose over time due to oscillation. It's a good habit to give it a quick turn before you head out. Also, check the electrical contacts. The brass pins on the j arm that tell the unit in order to turn off whenever flipped up may get dirty or corroded. A quick wipe with a cloth or perhaps a Q-tip with a bit of alcoholic beverages keeps the connection snappy.
The rhino mount itself offers a lot associated with little springs and pivot points. In the event that it starts experience "gritty" whenever you turn it up or down, a small drop of dried out lubricant can make it feel brand new. Just prevent anything too greasy that might attract dirt or sand, as that will just make the problem worse over time.
Final Thoughts for the Classic Combo
At the end of the day, the j arm and rhino mount combo is really a traditional for a reason. It's the gatekeeper to the world of night vision. Sure, you can spend $500 on a Wilcox mount and a specific arm, and you'll definitely notice a difference in build quality and "cool aspect. " But in case you want a setup that is proven, rugged, and gets the job done, the j arm and rhino mount are impossible to beat for the price.
It's all regarding obtaining the gear out of the way so that you can focus on what's ahead. Once you've shimmed the particular wobble and dialed in your attention relief, you'll realize that this "basic" setup is actually the very capable item of equipment. It's not about getting the most expensive mount on the range; it's about possessing a setup that remains put when you need it to and allows a person to see clearly into the evening. Don't feel like you need to rush into the priciest updates right away. Spend time with the rhino and the j arm, learn their quirks, and they'll serve you well with regard to a long time.
