What are advantages and disdvantages of using a monocular goggle versus a binocular model? I would imagine that using NV devices on both eyes would provide depth sense, which would be fundamental for night operations. However, as military forces seem to prefer the monocular version they should offer more advantages. I'd appreciate any comments and suggestions. Thanks in advance. |

generally speaking "binocular" goggle models aren't, they use both eyes but offer no more depth perception then TV both are easy to drive with, but walking is a huge pain with goggles compared to a monocular a monocular is much easier to use with weapons as well, either mounted on the weapon or head mounted (weak eye) with a reflex site - your brain will super impose the reddot on what your other eye sees, it takes a bit of getting used to but works fine for me I honestly can't think of any advantage goggles have over a monocular, and they are usually more expensive as well |

Quoted: Binocular night vision will give you depth perception - a monocular won't. Little importance - big cost. I think he means the "goggles" I doubt anyone is willing to pay for or carry around the HUGE binocluar goggles, they are to big to walk around with, and most of the goggles like anpvs7's are not really binocular, even most of the twin tube models are not binocular |

Thanks for the replies! Yes, I was talking about binoculars. That is, two tubes. I would use an IR laser in combination with it. Would the solution above be a better close range solution than a monocular and an Aimpoint type device used in conjunction? I'm trying to understand the pros and cons of each in order to make a decision. Cheers! |

I've got a pair of PVS-7Bs and a PAQ-4C, they work just great. But, if I had to do it over again (or had a lot of cash again) I'd buy a AN/PVS-14 or USNV-14. Moving around with a monocular is much easier than the goggles at night. It also works just as well, leaves one eye dark addapted and is lighter. Even if using an IR laser, go monocular, I wish I had, even though my AN/PVS-7s are prefectly serviceable and will keep using them. mrf2 |

I have both dual tubes and single tube systems, so here goes.... dual tubes pros: stereoscopic view - much safer when operating a vehicle -, slightly better depth perception than a single tube, but still rather limited. redundancy - if one tube goes out, you still have another less strain on the eyes because both eyes are working in conjunction the night vision better performance Cons: higher cost - paying for two tubes heavier....not as comfortable under prolong condition one tube could be brighter than the other - no two tubes are exactly alike need to focus each eye objective independently - two to mess with eyes may encounter temporary blindness if goggle/binocular were to be accidentally knocked off while operating it in darkness Single tube pros: lighter in weight and less bobbing/movement when running allows the un-aided eye see normally - e.g. read instrument or map un-aided eye won't go temporarily blind if the monocular were to be knocked off in darkness weapon and camera/camcorder mountable Cons: not recommended for driving, but could be done with practice. dominant eye issue - generally want to wear the monocular over dominant eye lack of stereoscopic view |

Do you guys actually own this stuff. I'm just curious. I'll tell you the truth, it just doesn't come up all that often for me. And I don't have open access to that stuff anymore since I retired (something I definitely took for granted and miss). But I live out in the desert and I'll tell you, there ARE times when I wish I had a set of company NVG's in the trunk. It's amazing what you DON'T see at night because you can't see in the dark (see Gulf war's I & II). I just got around to buying my own GPS! Guess I took having free access to those for granted too? I need to catch up. |
