We're big fans of dual mounting PVS-14's. It's a very popular way to get into a dual tube binocular type of system considering most users start off with one PVS-14. At some point every monocular user is going to want or be interested in duals. The options are 1) sell the -14 using the funds towards a bino device, 2) cannibalize the -14 using the tube and optics towards a bino, 3) keep the -14 as a loaner/backup and buy a bino, or 4) buy a 2nd -14 and dual bridge mount.
If you already have a -14 the odds are that you own it. Going the dual -14 route will be cheaper than a bino in terms of cash out of pocket at this point. A big reason we like dual -14's so much is that down the road if you decide to sell gear to help fund new gear, it's much easier to sell the -14's individually than selling a complete bino device.
If going the dual -14 route the single biggest consideration is weight. You want to keep the weight down as much as possible. The next item is how do you want them to function. Do you want articulation like PVS-31's, -15's, or other BNVD's? Do you want quick disconnect capability, need to attach something to the front such as a thermal COTI, or possibly use a FLIR Breach occasionally in place of one of the -14's? Do you want a dual mount you can start off with your single -14 and add the 2nd arm later when you buy a 2nd PVS-14?
Luckily, there are several mounts that fill these niches and at various price points. Here's a list of the most popular ones. We personally own the D-14 and TNVC NPBM which you can see in our videos. There's a D-14 mount mini-review in the first half of our Dual PVS-14 vs BNVD video that you can find on this site or You Tube. You can find the TNVC NPBM review there also.
Listed prices are in USD and the range is based on Google searches & vendor websites.
Highest to lowest prices:
- RQE (Red Queen Effect) Universal Dual Bridge $700 - $ 1,200 USD (bridge & additional shoe sets for -14's and other devices like FLIR and. Single & dual arms)
- Wilcox Binocular Bridge System $800 - $1,000 USD (single & dual)
- TNVC PBM (Powered Bridge Mount) $765 (dual arms only)
- Mod Armory/Integrated Components D-14 $575 (quick release function with additional arms available for FLIR Breach)
- N-Vision Dual PVS-14 Adapter $475 (dual arms only)
-Mod Armory/Integrated Components D-14 LW (Light Weight) $350 (dual arms only)
-TNVC NPBM (Non Powered Bridge Mount) $315 (dual arms only)
All of these mounts are great and offer their own distinct advantages & disadvantages. We can only share our opinion on the two mounts we have used in this list. The D-14 QD model is excellent for quick detachment capability, is very solidly built, and is heavier because of that at 5.1 oz. The TNVC NPBM is a very light weight at 3 oz, doesn't have QD capability, and is the lowest priced dual mount of this bunch.
We'll use the D-14 for when we'll be taking pics/vids as the QD function is a time saver for attaching cameras. The NPBM is the choice for when we'll be using our devices with no need for QD. Lighter weight makes a big difference when you're wearing duals all night long.
You ever get a chance to try this one from N-Vision optics? https://tnvc.com/shop/n-vision-dual-pvs-14-adapter/?doing_wp_cron=1562626991.0612978935241699218750
I've seen it used to bridge two ENVIS and I was thinking about doing that (I have thee ENVIS laying around) to have a cheap set of duals to beat on.
I haven’t tried one yet. It looks like a decent mount. Last I talked to N-Vision they weren’t making that one anymore. If tnvc has it I’d snag it before you can’t find them anymore new
