Looking at bringing some thermal into my hog hunting. These are the cheapest I can find that still having a good reputation but the reviews I have find are really not great.

Main use will be seeing 100-200lb hogs at 100-150 M

Does anyone have any experience with them?

The refresh rate is what is lacking in the lower priced units, but they will allow you to see a hog in the dark.

I have the Leupold Tracker 2, non HD.

It picks up deer out to 150yds for me, but beyond that it's just a heat blob, you can't tell what it actually is. It really excels in finding the blood trail (hence the "Tracker" name).

I do like the different color setups that it offers, and being able to select the "high ambient" to not get a warm tree covering an animal.

I got it with some Cabelas gift cards I got through work, not sure i would have spent the 700 if it wasn't for that.
