The weird thing is there *is* a safety screw hole in place there, but it doesn't matter if you take it out.

@@YAGERMFG interesting, what I was saying was simply a guess anyhow.

Yes, it can

The flickering isn't just about being ugly and annoying (although it is) - it's about what it tells you about their electrical engineering (probably not good). If a competent electrical engineer had their say on this design, they would probably either use a much higher frequency PWM or a constant current regulator. The flickering suggests to me that there was either a poor design process or cut corners.

@@YAGERMFG It's most likely intentionally done instead of a poor design process. It's to increase battery life in comparison to the EOTech design. In order to completely eliminate this (it's called the phantom array effect, visible only during very quick lateral movement), an extremely high pulse frequency rate is demanded. To entirely eliminate it will want nearly 2000 Hz. Trouble is in order for the laser diode to have a stable wavelength (which is necessary for undistorted reconstruction of the reticle hologram and point of aim shifting from the point of impact), avoid multi-mode operation, and keep the diode from generating so much heat it kills itself the only method left (besides something physically in the path of the beam like a polarizer that could be rotated) to be able to adjust perceived brightness to the user is to run it in duty cycles with pulse width modulation to exploit persistence of vision. Combining the two, pulse width and pulse frequency modulation requires confronting the constraints imposed by a laser diode. Generating that high of a frequency requires pulses that are separated in nanosecond scales. In the EOTech design a microcontroller was needed to send 2 pulses at once through separate circuits that have slightly different resistance from one another. It is IMO a poor design decision by Vortex but there have been some issues with parasitic battery drain, so I can understand Vortex not wanting to exacerbate that if they have been unable determine the cause of the excessive drain some of them have. If they have though they should just bite the bullet and accept the lower battery life to avoid the phantom array issue. People who see the value in holographic sights do not care too much about the battery life, they expect it to be short.

@@RocketPropelledGuy interesting explanation, but frequency and modal stability under ~1-2kHz PWM with, say, 10k:1 max duty cycle ratio, should be very doable with modern diode lasers.

@ right, this is why it seems more like intentional, a poor design choice rather than someone not pointing that out

I would not recommend EOTechs due to their gas leak problems (I have killed several that way), and I would not recommend vortex for the reasons given in this video. Just stick with aimpoint if you want an RDS

The battery pack has electronics in it. It has significant parasitic drain even if not connected to the thermal imager.

@@YAGERMFG weird if I use the power button on mine it doesn’t drain at all when hooked up I figured it out cause it used to if I left the battery pack on even when device off maybe test out what I said in first comment

@@YAGERMFG I’ve had mine plugged in and all hooked up for almost a year now without touching it and it turns on and ran for hours use the power button on batt pack if u dnt shut the pack off it will drain mine used to till I figured it out

If you would like to buy me a $10k safran unit, I would be happy to do a review

The flickering reticle is evidence that it's poorly made, which you will definitely notice if it breaks during a realistic use situation. Low frequency PWM = low quality electronics design.

@@YAGERMFG If that was the case, you would hear about that failing. As of right now, battery drain is the issue everyone complains about. Haven’t heard of the reticle dying.

Battery drain is related to the quality of electronics.

I used to work in a research lab that did a bunch of optics work, but I'm also just a big time optics nerd

Yep!

Read through the comments - someone else asked the same. Short version is "depth of field"

What Micro 3x are you refering to?

@@jerryshafer1688 there is only one micro 3 it’s made by vortex eotech has there brand and holosun has there’s

@@jerryshafer1688 so the g43 is made by eotech and hm3x is made by holosun vortex is the micro3x bud so that’s the one I’m referring to

what? this optic is extremely heavy haha. theres nothing light weight about it.

@@maximusjoseppi5904 well if you lift weights and workout and not lay around it wouldn’t feel heavy ha ha ha . I run it with a micro 3x and it’s great and not heavy ha ha

Regardless your optic is completely separate from the laser/illuminator. You don't shoot your laser through your optic. You actively aim with the laser. If you want to shoot passively. Without a laser, You need an optic with night vision capabilities to shoot decently.

What has the optic to do with the laser?

They're my corporate sponsor

I'm not sure, but I would suggest spending the money to upgrade your monocular before buying thermals

@@YAGERMFG ok thanks

Objective lenses, either on a camera or on NVGs or elsewhere, effectively gather a separate copy of the image from every point on their surface. We're just blocking a few of those copies. If you take a small object and hold it directly in front of your pupil, you'll be able to see "around" it as well.

I just set the camera to max white balance adjust. Could also do it in post as long as your camera has WB lock
