This is how it appears for me. Or rather I should say this is as close as I could edit the video to represent the actual image.

The thermal image will not be perfectly overlaid and will lag behind the analog image.

The thermal is a FLIR Breach mounted on one of the mini-rails to achieve a “portrait” display image. This is only possible with the Breach AFAIK so with other thermals the image will be in landscape but otherwise appear similar in terms of how it overlays. I find that the Breach’s Outdoor Alert and the Sidekick’s Target work the best in this type of setup. The partial “hits”do a better job overlaying than a complete thermal image.

Hopefully this gives you an idea.

As for whether to do it or not - some guys love this setup and others hate it. I only recommend doing it if you have a reason to utilize a head mounted thermal for longer term scanning or use of thermal such as a hunting. Otherwise, I personally recommend to skip carrying the extra weight on your head and just use a handheld.

We haven't had one of these threads for a while so I'll give some more info learned from my experience using dual band setups.

If you're chasing a "fusion" system then know that a dual band setup like this may not deliver the results you are looking for.

Some individuals can make it work, others can't, as well as the thermal itself may not be capable of it. To have the best results the thermal should be optimized for use as a monocular (big as possible display and 1x magnification) and have a X/Y screen adjustment capability.

With the X/Y adjustments you simply "walk" the thermal image over on top of the night vision image while looking through both devices. The bridge also factors in. You need a bridge that can mechanically optimize the position of the thermal with IPD adjustments to assist the X/Y screen adjustments. The Rayvn Rail and the new Noisefighters Panobridge M1 are the best choices. You will need an adapter with the M1 and they have two choices - a QD dovetail or mini-rail. Select the one based on the thermal. The Wilcox can also work well with a thermal with a dovetail shoe except the j-arm that comes with it doesn't position the PVS-14 in an ideal manner to be compatible with all thermal devices for right eye use of the PVS-14/NV monocular.

I always tell folks to plan on using them individually one at a time. This way if you can't make the thermal overlay work then you won't be as disappointed because you already know going in that you may use them individually. Some guys will simply close the eye they don't need vs articulating up/down the devices.

Honestly, if you don't have a real need to be on the thermal al of the time, then I would just use it as a handheld. Also, depending on your area/use you may actually want something with a higher base magnification (2x for example) vs a 1x. 1x is what you'll want for a dual band HMT (head mounted thermal) setup. If a 1x magnification works for you (mainly shorter distances say under 300 yards) then I think it's worth a shot if you're okay spending the $375-$500 on the bridge that might sit in a drawer. If you live in big wide open spaces then you will likely be happier with a higher magnification in order to better detect/ID things way out in the distance.
