Now as to why I replied to this thread. It was asked about a Thermion holding zero. At least for me, with my one unit, I can speak to that.
2 years ago I had saved up and bought a Trail XQ50 LRF. Pretty much right from the beginning I had shifting POI issues. Very significant POI shifts. I do lots of precision rifle shooting and a rock solid zero is important for me. I did lots of testing using a very accurate, repeatable rifle and documented my issues thoroughly. My dealer backed me up on it and I got a full refund from Pulsar. After reading about all the Trail POI shifting issues I just was not ready to go back down that road. The Trail 2's were not out yet and not expected for 6 months or better.
To replace the Trail I got a Thermion XQ50 with the dual lever American Defense QD mount. Over the last 18 months I have tested that unit hard. On the gun, off the gun, hot, cold, swapped around on different rifles using different zeroing profiles, you name it. There may have been a few minor shifts here or there that could easily be attributed to poor shooter form, a freshly cleaned rifle, or some other type of issue that can happen with any optic (thermal or daylight). But by and large it has stayed zeroed exactly where I put it and I have not seen anything that has made me question the optic itself.
After my initial experience with the Trail shifting zero it took quite a bit for me to trust this Thermion fully. But I do now and never give it a thought any more. I have killed over 150 pigs and coyotes with it in the last 18 months or so. Ranges from 26 yards to well over 300. It has been solid for me, I trust it.
That doesn't mean someone else somewhere may not be having issues with one. I can only speak for me.
Your experience with the thermion has been exactly what I have experienced. Set it and forget it. I ran the Thermion XP50 for 2 seasons and never once had to make an adjustment...it didn't matter whether it was hot, cold, daytime, night time, summer or winter...when I would just check it to see...it was always only a one shot check...dead on where it was set from the beginning...and when I say dead on, it is exactly dead on...not this 1/2", 3/4" or more off stuff...dead on! I upgraded to a Thermion 2 XP50 this year and it has been the same...I have not had to change from my original settings that were done in September and I have checked it twice so far and it is dead on...again...not just close enough...I mean dead on! In fact I just checked it today before posting this and it is currently 12* with a 14mph wind that puts it close to 0* windchill and it's exactly dead on.
The other convenience of the Thermion is the fact that it will mount on a bolt rifle or AR with no extra extended rails needed and you really don't need any special kind of mount. I just use a set of 30mm scope rings and that's it. The videos are very good and sharp and the internal audio is good and clear. The Thermion 2 XP50 has a slightly clearer image over the straight Thermion XP50, but a lot of people may not notice it. As for batteries being an issue, I have never run out of battery running it for 6-8 hours and using the sleep mode a lot when on stand...I honestly think I could get 10 hours of run time doing it this way. I am using the APS3 battery and carry the APS2 as backup, but have never had to change batteries.
So I guess I am a Thermion fan and this is not just internet BS...my hunting buddy will back this up and he too is running a Thermion XP50 with the same experiences. For the record, I started out with a Trail XQ38 and ran it for 3 years and never experienced any POI shifting with it.
I wouldn't mind trying a Super Yoter at some time but for now things are working.
