New member here. Been doing some reading here & liked the thermal comparison you guys did. Wow! Thanks for doing that, what a lot of work! I don't know if I will be in the market for a thermal this year but did hope to learn from you guys. My hunting would be limited to coyote & fox in the cold weather we have here in illinois. I understand 30 hz is sufficient for calling coyote and higher hz isn't really needed. I also read the OLED display is better for cold weather use. There are several models that catch my eye. Pulsar apex 50s, Armasight Zeus, & ird mark 2. This scope will be on an AR platform in 204 ruger. Most shots will be between 50 yds & 200 yrs. Do you guys recommend renting each before buying? Does anyone here do that? How do you guys feel about positive ID with thermal scopes? I read a lot of guys saying you can't ID with thermal & run the risk of shooting someone's dog etc, etc. I have a Pulsar hd19a and at times use the animal's movement characteristics to help me decide what it might be but use my gen 2+ scope to ID & shoot. What makes the mark 2 worth so much more money? I appreciate & look forward to you sharing your experience & insight. Thanks!
