    Field of View

    Thank You Henry, This thermal has a base optical setting at 6X with additional 2X and 4X digital zoom - so, at 100 yards I'm only observing 15' of terrain at base optical magnification? Probably have to look for a 1.5X or 2X optical base magnification for a decent FOV at 100 yards and closer.

    Field of View

    I have a question that possibly someone here has the knowledge to answer. I was looking at a thermal night scope that expressed the FOV as 3*X2.5* with an optical magnification of 6X with a lens diameter of 75mm. I would like to know the formula to determine the FOV in feet/meters at 100 yards.

    Vortex Viper UHD beats Zeiss SF and Leica Noctivid!

    Yup, some optic companies have great warranties and customer service here in the USA. Votex and Leupold are but just two of them. I know a fellow who had his Vortex Viper become separated from his ATV at 25 mpg on a very rocky trail. He told me he thought the view through them wasn’t quite...

    P900 in cool wearher

    Does anyone know if one could take pictures with the P900 in weather conditions of -15*F without possibly damaging the camera. Wouldn’t be in those temperatures for more than 8 hours.

    Nikon Monarch 7 8x42 or Nikon Monarch HG 8x42 if the price difference is $750 CAD ?

    The OP seems like he wants “quality” and the idea of “what if” will always be in the back of his mind. If that’s the case, by all means return them to Amazon and get the HG. That extra $750 Canadian will bring you peace of mind and better glass to boot. Whether or not your eyes are good...

    New Ultravid HD-Plus 'Customized'

    Permethrin is the active ingredient found in ThermaCell pads, which performs great in certain environments. We use 4 units at each corner of our A-frame cook shack that has excellent ventilation. I have tried several different means of mosquito protection to include 100% Deet. Once you...

    New Ultravid HD-Plus 'Customized'

    Back in the late 50’s and early 60’s in a far away land, men of the 101st had little green bottles of 100% Deet to keep any and every biting insect away from their flesh. Worked for that purpose as well as molding your fingerprints to steering wheels and giving a tinny taste in your mouth...

    Best mechanically built binoculars today ?

    Binastro, post 45. I’m still smiling after reading that post. If you didn’t have bad luck, you wouldn’t have any luck at all. I’ve actually fell from a 6 foot hide while hunting, but as any good sportsmen will tell you - you protect your firearm and optics at all costs - meaning your body...

    When will the current alphas become 'obsolete'

    I would think if the military feels the need for digital binoculars it will come to fruition in short order. I doubt the military feels the need, as drones can see in all conditions. Years ago there was a small niche for civilian thermal rifle scopes, as the price for a good one exceeded $25K...

    7-8x boat and birding

    I usually have a binocular in the boat/canoe and keep it in a zip locked baggie usually in a soft shell case that will be open, if I think I'll have quick use for them - same with a small zoom digital camera. I can retrieve my binocular and have it up to my eyes in 5 seconds if need be - takes...

    Large back pack for camera gear.

    Depending if you want dual use from your backpacks - maybe look over some items from these manufacturers: Equipment from these vendors will last several decades with hard use but the initial up-front cost is rather high. If you're not into outdoor camping where you spend several hours getting...

    Binocular Classifieds

    Sniper's Hide occasionally will have great deals on slightly used binoculars and spotting scopes, although the vast majority of optics sold are rifle scopes.

    Diopter Setting Consistency

    Well, that's close enough for Government work to be called West Texas.|=)| I adjust the diopter on my 1st use and after that I never think of it again - really don't know why I adjusted on my 1st use, as the focus knob always works great - could be my father talked about it many decades ago -...

    83x anyone? The new Nikon P900

    Got in another hour of training and now know a little more relative to photography. I now understand how to use the "program mode", whereas previously, I never had a solid understanding as to how the shutter speed/aperture/ISO danced together to produce the "best" picture. I kinda...
