You want to avoid Gen 1 at all costs
Can you describe your typical hunting setup (walk & stalk) , ground blind, elevated blind, heavily wooded, wide open senderos, etc...
For your budget you are looking at either Gen 2 or digital technology
You can google:
Armasight Drone Pro
and from those companies above you can look at their Gen 2 products as well.
Lots of options, and yes very confusing.
