So - relative to NV costs - I'm on a relatively shoe-string budget in trying to put together my personal NV gear - but I was pretty sure from the get go that a dual tube binocular setup was where I wanted to end up - it took a lot of searching, researching (and re-searching), and horse-trading to get here, but a lot of folks here in the NV forum have helped me out along the way.
I think I'm pretty much set in terms of the device itself, minus a couple small things that I'd like to do - until I can ever afford an actual BNVD setup, which will likely be a long while off.
While it's not the perfect or most ideal setup, it works good-enough, and I'm pretty satisfied with what I ended up with for the time being - over the course of the past year, I've been able to horse-trade into two PVS-14s - unfortunately, they were pretty different, specs-wise, and I had some initial concerns about how well they would work together - one is an OMNI VII autogated tube, while the other is an OMNI III non-gated tube -
So - in order to determine whether it was even worth trying to tether them together - I put together this proof of concept:
Needless to say, it wasn't the most stable, durable, or practical setup - but it told me what I needed to know - that I could get my eyes to integrate the images from the two disparate tubes into a single, worthwhile, dual tube, stereoscopic picture.
Once that was settled, TheHorta was (is being) kind enough to let me borrow his MOD Armory PVS-14 bridge - which is a great unit, with lots of features - and well engineered - but a little heavier and taller than I would have liked to have been. The height issue essentially forced me to crank the elevation adjustment on my old-school Norotos TATM further than I had wanted in order to get it to align properly (adjusting the mounting holes of the mount on the AKA2 mounting plate probably would have quickly solved that) -
Not long thereafter - I was able to score a great deal on a used N-Vision "standard" bridge mount (not the Advanced), which I had determined would probably be my best bet based on what I was looking for versus weight (at least until the Wilcox bridge comes out, and I'm left salivating at another piece of Wilcox gear I can't afford yet
).
In the "factory" configuration - it's a pretty good, pretty simple and relatively lightweight mount:
Because of my relatively close set IP distance - in this configuration, it was still a little taller than I might have liked - and the location of the dovetail was a little too far forward for my liking - more on this later. Inevitably, the urge to tinker came about, and I ended up disassembling the entire thing into its component parts:
I then reassembled it with the mounting hardware backwards, and the rings "upside-down" in the mount:
Doing so allowed me to adjust the screw for the friction fit of the adjustment "just right" so that they would generally stay in place - and as a bonus, with the screws to tighten the rings for the monoculars oriented inside now, rather than outside - when the monoculars are brought as close together as they will go, the IP distance was
perfect for my eyes/face.
Turning the mount around, likewise gave me more lateral adjustment fore and aft, which, combined with re-orienting the rings, opened, at least for me, a whole other set of possibilities -
In this configuration - here it is with the proper eye-relief for use/regular wear:
Extended to full forward adjustment, it looks like this:
(it's hard to tell - but the edges of the monoculars just barely clear the lip of the helmet)
The sum result was to allow this:
Seen as worn during "normal" use -
Stowed -
Stowed - with the monoculars folded back -
Better yet, though - with the NODs pushed all the way forward on the mount, and clearing the lip of the helmet -
One monocular can be rotated up - it's not a perfect and clear unobstructed view - you can still see the bottom edge of the monocular, but essentially, it's a 90% solution if, say, you're going from a deep brush area to a more varied illumination urban area, for example.
You can also do this -
Once again - while you can still see the monoculars in the top of your field of view, the upside-down rings allow you to get the monoculars pretty "flat" when stowed - getting them almost entirely out of your FOV.
Here is where the "on the fly" elevation adjustment of the Wilcox mounts could be pretty useful compared to the more precise, but much lower, and much more awkward to operate Norotos screw adjustment - as bringing the mount to max elevation gets the monoculars even further out of your FOV - as does being able to bring the NODs out far enough to clear the lip of the helmet.
They're certainly not perfect - they're still heavier than they need to be (by sheer virtue of having independent controls and power supplies), while independent controls complicate operation (though I suppose they make the
ad hoc monocular configuration possible), and perhaps are not as solid as a purpose built unit might be - PVS-15s, BNVDs, or Sentinels, these are not - and I'm sure I'd be even happier if the tube specs matched more closely - but I'm pretty satisfied with what I've got - and I think these will keep me happy, likely for several years until if and when I have a major change in income flow and can afford one of the aforementioned purpose-built units.
The only things I really want to change now is to replace the dual-AA power supply on the one monocular for a lighter and more streamlined single-AA power supply, and get my grubby little paws on a Wilcox G24 mount - the TATM is a great mount - but IMHO, there are definitely things (having had the opportunity to try one out for a while) that the G24 will lend to this configuration, such as the "on the fly" elevation adjustment.
No "in-action" shots yet, unfortunately, but I've taken it out a good bit so far, not as much shooting as I'd like - but overall, it's a great setup for me and my needs - hopefully I'll have more to add soon!
P.S. - I notice now that with the chinstrap tightened and the rest of my face blacked-out, my chin pubes look awfully scraggly and disgusting... I'd like to point out that I shave once a month on average, and these photographs just happen to be from about a day or two after one of those occasions.
