content: I would really like to see the constructions inside these Boson based scopes, but zero info are on the internet. Anyone?

content: Here are some. The core was removed. A DIY battery compartment is shown here, you can use three 18650 batteries.

content: I've read the manuals for them, it seems they all use the same eyepiece LCD, and have ability to save photo+video onboard, and UVC output. Scion have GPS+WIFI+BT, while Breach and ThermosightPro don't have GPS/WIFI/BT, am I right?

content: I don't have the Breach and ThermosightPro, but got one PTM and two OTM cameras. PTM and OTM series have ability to save photo+video onboard (or a external TF card), they have digital UVC output (It's a great pity that there is no analog video output) , and GPS+WIFI+BT. You need a special app to stream to your phone. The Flir recommended App has significant latency and seems to be useless.

content: Thank you.I think GPS and WIFI streaming are OK (GPS do not have overlay?). But BT for microphone(instead a $1 mic inside)? NFC for wake-up? It's a professional monocular, not a phone-connected toy!Yes I prefer analog video as in Scout models, but those don't have photo/video capture capability... They just cannot make a perfect product.

content: I didn't test the GPS outdoor, just put it near a window but can't get any satellite signal. Never try the BT and NFC. But I have to say the display (Quad-VGA, 1280x960) is far better than the Scout. The Scion series, though, is relatively big and heavy, especially the PTM466; it gets a bit heavy once fully equipped with batteries. The Scion series also seems to have a power protection issue. If you remove the batteries right after turning it off, the device sometimes won’t power on—you have to wait a few minutes before trying again. Many buyers have run into this too, thinking the device is faulty.

content: Quote from: RRtheone on September 29, 2025, 12:57:48 amThis is good news, since the scout display is ridiculously bad: narrow FOV combined with low contrast.The scion/breach still don't have a wide enough FOV, from the datasheet they are around 24 degree horizontally. (Scout series don't even have that data.)Any ideas on how to enlarge EVF's FOV/magnification?

content: Not sure why you would like to enlarge EVF's FOV. The EVF is a OLED or LCD.You said "scion/breach still don't have a wide enough FOV, from the datasheet they are around 24 degree horizontally", this FOV is determined by the objective lens and the thermal core.See here:https://oem.flir.com/boson-family/boson-fov-comparison/

content: Quote from: RRtheone on October 09, 2025, 02:24:23 pmScion/breach have many different objective lens configuration options, but their eyepiece FOV are always 24 degrees HFOV, relative to human eye. ThermosightPro are even narrower, at 18 degrees HFOV, maybe because their longer eye relief?

content: Quote from: 5au12 on October 09, 2025, 01:37:32 pmYes I just checked other forums and absolutely no one understand me, I'm so frustrated. Is there anything wrong with my expression? If so please suggest me a better way to express my meanings.Well I'll try it again, think about two video glasses both connected to a PC showing the exact same thing(maybe a BIOS error screen). One glasses is a cheap old FPV glasses, the other one is a VR glasses. So they now both showing the same picture with same total pixel counts, but to naked human eyes, one is much bigger than another.

content: You are describing “Eyepiece magnification”.The FLIR products are infamous for having poor magnification of the Kopin miniature LCD panel. A larger LCD panel is the preferred improvement rather than higher magnification EVF optics but this is a decision made during design and not a modification that I can recommend. To increase the magnification of a standard FLIR EVF you would need to source new optical elements and that would not be simple. Camcorder EVF assemblies might provide the required parts but camcorders often use a larger EVF LCD display size so you gain nothing in terms of optical magnification. Most users learn to live with the FLIR EVF or change to another brand of thermal scope that uses a better EVF design. Some users fit an external field monitor and use that instead.Fraser

content: I did a quick search and it appears that there are viewfinder magnification attachments for photographic cameras. This may be an area worthy of your investigation. Do remember that you could lose eye relief.https://www.fujix-forum.com/threads/magnifying-your-x-t30-evf-to-the-larger-size-of-x-t5-or-x-t3.148539/Fraser

content: Thank you very much Fraser, finally someone knows my needs.Well at this point it would be the best option to just take out the Boson and use it with a monitor.The add-on lens reduce eye relief, and the magnification is not even close to what I need.There's no off-the-shelf UVC monitors.

content: I'm also thinking, what if I use a small microscope? The display itself is a plain surface, just like specimen stage. What are the common microscope FOV to naked eye?Or a CCTV camera with a suitable lens focal length, then connect it to a monitor.
