It's a microscope with a camera mount on it. here's the specific one he uses
recomment with full damn link monster because of stupid rules
I've been using one of these... https://www.amazon.com/AmScope-7X-45X-Simul-Focal-Lockable-Microscope/dp/B01H4FOLVM/ref=sr_1_15?crid=2FD9AHHHTT3BA&keywords=amscope&qid=1640333905&sprefix=amscope%2Caps%2C119&sr=8-15
It's nice with a camera in the third eyepiece.
I think this is the one I have. It's stock except for the 0.5x Barlow Lens and a light ring. I don't have a set magnification. It's just adjusted as needed.
I know what you mean about the Mantis. I have one at work. I wear glasses and not having to perch them on top of my head is nice.
I have this one. Optics are fine. Don't buy the AmScope ring light, it's a piece of crap.
Got this.. plus HD camera ($100), and .5x adapters on both ends..

Trinocular is the way to go. You can record what you are doing WHILE using both eye pieces. Some will get a version that you have to disable one eye piece to see the visual to the camera.. the one I got uses all 3 at the same time. So if you want to record.. or put up on a big screen (hdmi out).. you can.
There are smaller models with 7x to 45x zoom as well. Honestly I don't think you need even 45x.. 20x and you're more than zoomed in enough. It is a little odd looking through eye pieces while you solder.. but the two eyes allow you to see depth of field better. If you can work on an HDMI only option.. e.g. can work around the depth of field issue.. you can get a cheaper $100 digital camera.. and those work well.. basically just like the 3rd port on this one I linked.. use an HDMI screen, etc. I couldn't figure it out. Trying to match up the solder in left hand with iron in right.. was too hard.
