First range test under our belt, and I'm very impressed with some things and a little more grounded in my expectations for these units.
Brought a handful of rifles out, and did a shooting test with a mk12-style AR with the 2.5-10x42 NF and a buddy's set up similarly but with the 4.5-14x50 mk4. Got a few more pics through the 1-10x24 vortex, but didn't shoot the thermals on the SCAR this time. We used some of the 1" ThermBright target repair stickers as aiming points on cardboard at 50yd. I believe
@DownRangeThermal sent those out to the lr night shoot we did in OH 2yr back. Based on the resolution we were getting on target, I think we'd have to cluster 6 or 8 of them together if we wanted to shoot at 100yd. Conditions were overcast with crunchy snow on the ground, at 24degF.
Here's an image showing the vertical offset with this particular setup. Definitely not perfectly centered, but pretty close.
The procedure outlined in the VooDoo-S manual and quick-reference card has you hold the rifle steady and flip the thermal back and forth in front of the scope to check for noticeable shift in the POA image. These images don't represent the shift, just the change in view for a target at 50yd. You can see the Wilcox mount blurry there at the corner of the scope image, as it wouldn't flop completely out of the way while the PEQ-2 was still attached. I didn't observe any significant shift when doing this first step - the thermal image seems to line up quite nicely in the scope.
Here was the shooting order we went through on this first rifle -
- Started with 10rd shoot-in after having cleaned the barrel recently, on dot torque dot #8
- A) 5rd 'zero' group with IMI 77gr, marked (A), showing POI offset approx 1" low and 0.5" right
- B) Install VooDoo-S in Wilcox mount, factory-reset and focused. Shot three rounds at (B1), removed from mount, reinstalled, fired 3 more rounds at (B2)
- C) Adjusted POI on VooDoo to +1 vert, +2 horiz, shot 3rd at (C)
- D) Adjusted POI to +0 vert, -2 horiz, shot 3rd at (D)
- E) Adjusted POI to +0 vert, +1 horiz, shot 3rd at (E) and was satisfied with matchup to day scope
Final adjustment to match up with the 2.5-10 setup was 1 click of horizontal.
We repeated the factory reset and got it back to 0/0 and put it on the other mk12-style rifle, which had 4.5x at the low-end and a bit closer alignment -
Did another zero confirmation before shooting with the thermal, then shot a group with it flipped into place and found zero offset between POA/POI at 0/0 adjustments on the VooDoo. Here's an example of what the target looked like at 4.5x -
After doing the shooting, we cleared things out and put the VooDoo on the SCAR that had the gen3 1-10 on it. Thanks for being our downrange thermal targetry,
@DOC-PGH ! This first shot shows the target backer at 50yd and the second shooter at 200yd, zoomed to approx 2x. The VooDoo screen tunnels out at 1x, showing the full rectangular perimeter in black.
Next is the same view, but at 4x -
And here's 10x -
I wasn't able to get a great shot through the 1-10 + the SkeetIRx, but here's one at the 50yd target. Its much wider FoV means less pixels in a given area and lower resolution on the target. The thermal target stickers got very mushy and it didn't like much zoom at all. This is about 3x, sorry again for the bad photo quality - the lens of the Skeet seemed to distort much more at the edges and throw off the camera focus.
Upcoming comparisons will include digital zoom added on top of the 1x unity perspective, and I'll probably continue using the 1-10 as it really seems like the best fit for something like this that gets quite pixelated above 4x.
In summary, it seems like a really great short to midrange clipon that delivers on the promise to deliver very minimal shift when set up correctly. Stretching much past 4x is probably not a great idea, and you don't get much resolution on warm targets past 200 that would tell you what they're holding, etc.
The manual (which is marked ITAR controlled) shows multiple examples of rifle setups and stresses the importance of the vertical offset between thermal and day scope. It mentioned spacers available to change the height of the VooDoo. You'll see here an EOTech on a Unity riser is obviously much too high to view through when using the Wilcox mount, and you'd need to raise it up on another riser or other solution to work well.
It's a really nice small size and feels quite sturdy. With the longer rifles we could barely feel the added weight on the rail. The knurled battery cap is a huge upgrade and the eyepiece stands out far enough to clamp a camera mount on.
By featuring a 15deg horizontal field of view, the VooDoo-S is a bit wider angle than the base LWTS (12.4deg), NOX-35(12.2deg), and incoming ClipIR (12.4deg), but not quite as wide as the iRay MH-25 (17.5deg) or certainly the SkeetIRx (22deg) or NOX-18 (24.3deg). It seems to really like a base 2-3x magnification, and gets too pixelated for my tastes above 4x.
Here's a few side-by-sides with the Skeet to show the difference in 22 versus 15deg FoV. While they're both presenting a 1x image to the viewer, the FoV on the Skeet presents much more of the scene and fills the eyepiece much more like a PVS-14 does. The VooDoo definitely feels like a small screen placed a distance away and needs that extra 2-3x to make the most of its resolution. I wouldn't take these images to represent comparative crispness between the two units, just a comparison of field of view. When zooming into the VooDoo, you would certainly have more "pixels on target" for a given subject. You'll notice each object within frame is the same size between the two, but the Skeet (on top, more blue) shows more of the periphery.
Here's a quick overlay to show relative screen size between the two units -
Looking forward to some more range time tomorrow, where I'll be focusing more on capturing video through the units to show how nice the thermal image really is at the distances it appears to be designed for. Will try stretching things a bit more and get some cows at 4-500yd, etc.
