Thought I would share my experience with this iray so far. I’m fairly new to NV and thermal so I won’t give any broad generalizations about what it is or isn’t, just some impressions from using it a week or so. Originally I’d wanted something like an Axion xq38. But thought I’d give this a try before getting one of those. Basically I wanted a pocket size unit that I can take for a lot of different purposes instead of feeling like I am having a dedicated thermal outing with a bigger device.
iRay FH25R, 640/12 um/25 mm/ 1280 display with LRF, <50 mK. all chinese ingredients of course.
-FOV is awesome. I would guess the base mag is about 1.5x or so. The intended use was for scanning woods hills / mountains. Definitely allows a quick scan.
-What I would call the depth of focus on other optics seems good. Meaning I am not constantly playing with the objective focus.
-The objective focus ring and lens cap are made out of a rubber that collects dust and small particles.
-The rubber eyepiece is a little too deep for my eyes. I guess someone with a flatter face tested this design
The solution is probably to trim the rubber down a little. Switching out the eyepiece with one of the other monocular models is another possibility.
-The LRF claimed range is 600m. I have not been able to test it much at distance. I am used to Geovid LRFs with instant numbers so it doesn’t compare with that.
-the size seems good to me but on the upper edge. any bigger and I’d have to start thinking about how big my jacket pockets are.
-The menu system seems solid and not too convoluted or deep. This is controlled by a line of three buttons on top. There are a handful of color schemes, 5 or so, and brightness, contrast, zoom. I have found myself using white hot the most. For me blackhot is just a little more natural for detection but then I don’t think this is very good at night even with the display brightness turned down to the lowest. I am not sure if this is related to the iray display or just a general tradeoff with all thermals. Whatever the case the white hot is effective I don’t feel like a lot is lost.
-It has PIP at 2x of the base mag and digital zoom to 4x. The PIP is nice. I don’t use the digital zoom.
-The spacing of the buttons on top of the unit are a little too close. Everything can work fine with some use, there is just not extra room.
-the display can we switched off to save battery with a fourth button on top. This does extend the battery but not to the extent of putting your laptop on standby or something like that. I believe the detector is still on and using power.
-This is integrated battery that charges via microusb. I would guess bat life around 4 hrs but have not ran it all the way down. Can be used while charging.
-The app works but is not polished. I was surprised how well the wifi streaming works. I normally don’t use these kind of bells and whistles however this got me thinking about mounting it outside of the truck.
