    Night Vision N-Vision Optics Halo/Halo-LR Technical Questions and Comments

    @wigwamitus SureFire batteries work just fine. Pretty much any battery with positive contact sticking out more than 0.04" should work fine (mechanically). Electrically, we have not seen any batteries that are causing problems. With full charge rechargeable CR123 go up to 4.2 V and...

    Night Vision Halo LR not holding zero

    @Eirerogue sorry about your troubles. In the future, it may be beneficial to write down your zeroing numbers for fast recovery in case of power failure. Please see my detailed explanation in the technical thread.

    Night Vision N-Vision Optics Halo/Halo-LR Technical Questions and Comments

    @wigwamitus Goog catch about our manual and the statement there about rechargeable batteries. Unfortunately, we were not able to come up with the list of "good" batteries or batteries that we really like. I will have to re-visit our manual. However, we strongly recommend the use of...

    Night Vision N-Vision Optics Halo/Halo-LR Technical Questions and Comments

    @Killswitch Engage, I was referring to the mount to the scope interface. It's the potential problem that is detectable in production. Mount to the Picatinny rail attachment is user-specific and we have no control over it. We can only hope that the user makes appropriate adjustments to the...

    @324matt Thanks for checking but I can't comment one way or another on our production or development plans. I hope you understand.

    Night Vision N-Vision Optics Halo/Halo-LR Technical Questions and Comments

    @PlinkIt, Halos switch both ways between power sources giving priority to the external input. I strongly _suspect_ that if internal batteries are present and working the effect of the misbehaving external battery will be at the very least minimized if not completely mitigated. However, we are...

    Night Vision N-Vision Optics Halo/Halo-LR Technical Questions and Comments

    Greetings! We wanted to give an update on where we are with investigations into the case of “Halo failing to hold zero”. Based on our testing, we believe that there are two distinctly different subcases that have occurred. 01 - We have examined a few units (few being less than 5 in this case)...

    Night Vision N-Vision Optics Halo/Halo-LR Technical Questions and Comments

    @slim023 thanks for good comments and suggestions. It is possible. Unfortunately, due to some specifics of the BAE core, there may be some limitations. We are thinking about it. Thanks. We will consider adding a simplified reticle later. It makes a lot of sense. Noted. I don't know...

    Night Vision N-Vision Optics Halo/Halo-LR Technical Questions and Comments

    @PlinkIt The current software does not allow to choose enabled zoom levels the way you want it. Sorry. We'll have to think about it for future software releases. Maybe we can figure out a way to do it. Thanks a lot for the idea!

    Correct. For reticles 7 and 8 on Halo-LR. Double it for Halo.

    Night Vision Halo LR not holding zero

    One extra comment about the use of the RCR123 batteries. I would advise selecting protected batteries. As long as they are not too much longer than the standard they should work. In the long run, the use of the protected batteries may prevent some ugly accidents that require a complete...

    Night Vision Halo LR not holding zero

    @PlinkIt it's hard for us to recommend any external packs because we don't control them and have no connection to the battery pack manufacturers. This being said, I know that some people had good luck with Anker battery pack but we didn't do any kind of careful evaluation ourselves. RCR123s...

    Night Vision Halo LR not holding zero

    @dang472 yes, the Halo/Halo-LR always default to the external power. Even more, when the external power is connected the core is always running. Turning Halo off while it's connected to the external power only turns off the display and the processor but the core is still on.

    Night Vision Halo LR not holding zero

    @car16smg it's highly unlikely that Halo scopes can be affected by any kind of malware. The processor and software that are used in Halo are not a common target for malware attacks. The much more frequent cause of problems with external battery packs is that voltage from some battery packs...

    Night Vision Halo LR not holding zero

    @slim023 this sounds puzzling. While I _may_ speculate about reasons why your scope got reset back to the factory settings (good you saved your reticle numbers on your phone!), I really don't like the fact that your zero shifted. It can be only due to mechanical issues and considering your...

    Night Vision Halo LR not holding zero

    Back from the Shot Show... I checked the report on this scope. It was not a software issue but a mechanical problem that we were able to fix without replacement of the scope housing. As a result, the serial number and velcro stayed the same :)

    Night Vision N-Vision Optics Halo/Halo-LR Software Update Available

    @Pkennedy is your right angle connector much shorter than the one that we are shipping? From the image a few posts back it looks about the same but it's hard to judge without numbers.
