by the way no ir was used in any way here, unless it was to aid in getting a better fucus (i only did this maby twice) i still dont have the battery for the famous trails irtazorac wrote:okay, i've used it outside at night and i was amazed! the conditions were overcast, but i live near a city, near teh water, so tehre was alot of light bouncing off the clouds, they GLOW orangy-red across teh water (not directly abouve me, alot of the situatoins were shilded from this)!compaired to my night owl the famous trails ft-300 performed better in all curcumstances i could find. it was very noticabley better with image contrast, and overall brightness. the only thing my night owl did better in was close up clarity, i think becuase the front lence may be slightly higher quality. you could see ferther and clearer with it simply because of the contrast. i spent maby around an hour finding different situations. at the end i was walking back to my house and i noticed a white fuzzy round object that wasn't moving, i thought it was a cat (a cat had been walking around our house earlyer) i brought out my famouse trails night vision, and i could clearly see it was a cat. (as well as detail on its face ect. it got up a sec later, and i followed it as it waked down the street. after it was a good 50-70 yards in front of me i took the night vision away from my eyes, i couldn't see it- even though i knew where it was, WOW! cool! then i took out my night owl and fired it up, i could see the cat, but not nearly as well as i could with my famous trails! i folowed it a bit more then went back home. in the time it took to walk back home, get inside lock the door, get a glass of water, go downstairs, turn on my computer and write this entire review the thing is STILL glowing! i dont know whats up with it but it glows for maby 20 minits after you leave it!!!
you jsut have to use it for a min then recharge it then it behaves this way, i dont know how it does it! this was a great buy! thats all for now!
i think mine is alittle different then yours, mine doesn't have a big lever, you would have to look at it for a sec to realize it was squeeze powered. http://www.onlinesports.com/pages/I,FMT-103007.html my expeareance was in seattle, wa. (not too far away) it rained last night, so that might be why, but sereously, one squeeze and your set for the rest of the night! it was amazing! but this morning it was back to a min maby! odd... by the way, do you have a link, or could you tell me how the piezeo crystrals work?Kalua1969 wrote:That self-powered unit is pretty much the same as an old Gen. 1+ of mine (Tasco NV150-L).... http://www.nightvisionforums.com/viewtopic.php?t=449
I experienced that same oddness of inconsistant viewing times, but in my case, I'm pretty sure it was due to extreme humidity. When I tested it out while here at my home in Hawaii, I would get perhaps 15 to 20 seconds till it quickly faded to black. When I'm at my regular home in Vancouver, WA I'd get close to 5 minutes on one squeeze.... *huge* difference.
My assumption was that the extreme amounts of moisture in the air would lessen the piezo crystal's effects in producing a strong charge (that's also probably that sound you hear when you squeeze the handle down... the crystals are being compressed together). The air in WA is much drier, therefore, the crystals were not moisture-saturated.
As far as tubes go, they're all Russian surplus stock. These are packed and marketed by different companies... which is often the reason why you'll sometimes see the very same scope offered by two or three different companies using different model names. My Tasco scope is the exact same design as ones sold by Newcon and Famous Trails.

Actually, the only difference is your housing, but the internal tube and piezo compression mechanisms are basically the same. Piezo-generated power has been around for a long time in all kinds of stuff (like your old quarts crystal wrist watches). Here's a quick link on piezo crystal technology...

Oh, just to let you know, I received the Infratech unit this afternoon. I plopped in a battery and powered it up with its daylight cap on. The image is sharp (virtually no geometric distortion), but the tube is obviously of lower grade when compared to my AN/PVS-7 Delta. There are about 6 or so tiny black spots, but I really don't see it as being a problem (considering that it only costed $500). Other than that, the unit is well-built and solid. I'll give her a quick test later tonight and see if I can post a review here tomorrow.

Nightvisionmall and OpticsHQ are based in California. I merely help Michael and Felix (owner and webmaster) out here in the forums with answering basic NVD questions, product recommendations and such.
