As I stated earlier, I own and use a Leica Calanox clip on. It is superb. You might try a step up in quality before deciding all European thermals suck. I am unaware of a truly advanced Chinese option of equal quality.
I am going to own it, I don't agree. I have used a lot of the European and Chinese models that Frankonia carries up to $3500. Spent days outside behind Zeiss, Leimke, InfiniRay and HK Micro.
Up to $3000, would not consider a European company.
$3000 and up to $5000 the European models will be woven into the better tiers, but not the best.
$5000 and up. There are damn few Asian ones in this price point. The top Zeiss, Swarovski, Leica and Leimeke/Blasers are in this price point.
All of them have the same Schott or Funjinon glass and features once you et to a certain price point.
Most of the European models are either wholly made in Asia, or mostly built in Asia and final finished in their European factories.
The Asian models are being updated multiple times a year. No European company is doing that.
I bought a HK Micro 35 series last year, for what the new 50 is upgraded to. My dealer told me that he doesn't know if he is going to get the Falcon 50's he ordered as they have updated them again and they are telling him he is going to get the more recent model as they figured out new tech and updated the manufacturing process again.
Every time I go into a gun shop in Germany they are all saying the same thing. The Chinese are winning the Thermal optics race.
My 35 is 18 months newer than my PH's 35 and has totally different letter series behind it. What a difference 18 months makes.
The clip ons are funny. I was on a hunting party about 15 years ago where one of my hunting friends shot a bovine heifer calf on a spotlight hunt. I am deathly afraid of shooting something and not seeing it 100%.
I really like night vision vice thermal on the rifle. Or at least I do right now.
Going to Slovenia next weekend. I am going again this fall. I am going to visit Optics Trade and see what they have and how they feel about it. They have thermal rifle scopes, hand held and binoculars. We are not allowed thermal rifle scopes in Germany. So I have not touched one.
