Know the property well. Yes cows there, some brush, looking for the best image possible.
I do like that Nocpix slim mentioned above. That one looks nice
Sorry, crazy busy past week.
Since you know the property well, you should be able to get by fine without a range finder. Just know thermal flattens the picture so judging distance is much more difficult. Spend some time memorizing distances during the day and apply it at night.
Cows on property and pig hunting can make things interesting when calves are on the ground. That's where a higher res core or higher base magnification scope come in handy.
You didn't say thick brush which opens up your options on base mag. In heavy brush I recommend higher base mag. You give up field of view but also cut down on the amount of stuff within fov that can reflect IR back and wash your screen.
Best image possible is going to mean a higher res core or higher base mag. If you get both in a single scope, it's a bonus.
Pulsar uses both Ulis cores (France) and BAE cores (USA). Here's the break down:
XQ - 384 core Ulis
XP - 640 core Ulis
XG - 640 core BAE

Both fit your need nicely. The Talion XG35 runs $2600 and the Thermion 2 XG50 runs $4K at normal pricing.
iRay / nocpix has good picture quality. iRay was my go to when Pulsar was fighting supply shortages. I'm still a little unsure about their spin off even though it's been a year. It doesn't make much sence to me that they don't just rebrand rather than add to an already very confused market.
Want to make it really confusing?? Bering optics uses iRay cores but their own firmware...
Hope this helps rather than further muddy the water. Have any more queations, please fire away.
