Looking at thermals and am looking for experienced advice on if a 60HZ is all that much better than a 30HZ to justify the price increase.
Basically is there that big of a difference?

60 hz eats batteries faster than 30 hz, not necessarily twice as fast, but the difference is significant.

At 30 hz, things look pretty normal and you get streak/smear when you pan quickly, too quickly to make out detail usually anyway. At 60 hz, that streak/smear of panning too fast largely goes away. The result is better slow motion viewing of fast panning or overall a slightly better image when there is lots of motion involved.

I don't feel that 60 hz will improve your hunting capability in any appreciable manner, but it certainly may improve your enjoyment of the scope.

If you opt to use an external power supply with rechargeable batteries, I would go with 60 hz. If you are not using external power and don't like the expense or hassle of changing of batteries, I would go with 30 hz.

What's the minimum sensor size one should look at?

Well written advice by DNS. As far as sensor size, I would say 320 or 336 according to the manufacturer are the minimum you want. Go with 640 if the coin is there.

640, buy once, cry once.

Plan on using my IR Hunter on 30hz mode til I figure out if i want a battery pack.

The minimum sensor size I think you should consider is 320 or 336. That was the standard for a lot of years and it works well enough for folks at normal hunting distances depending on the native magnification of the scope. As Tyler's poll (somewhere on this forum) has indicated, very few people will hunt beyond 200 yards at night and most won't hunt beyond 100. If that is your situation and/or you are on a budget, get a 320/336 core unit. You can get coyotes out close to 200 yards and hogs should not be a problem at that distance at all.

So it really depends on your need and finances. "Buy once, cry once" is a weird mantra. If you cry when you buy, then you bought poorly. Let's face it, when most folks daylight hunt squirrels at 25 yards, they don't don't buy a $2000 Nightforce scope for the job unless they have money to burn, right? They buy the right tool for the job, relative to what they can afford. If you are planning on hunting at 100+ yards or 200+ yards as your typical hunting distance, I would suggest going with the 640 if you can afford it.

If you can afford 640, then by all means, that is the way to go right now, even at shorter distances. Some people do hunt squirrels at 25 yards with $2K Nightforce scopes.

Then it is a matter of which one you want to buy, native magnification, and lens size. Lens size will have a significant impact on performance and on cost.

Thanks for the educated, knowledgeable information.
I'm actually looking at the Armasight Zeus Pro 640-30-100 30 hz.
That's why I was wondering if a 60hz would make it appreciably better for hogs/coyotes. I just don't want to be in the situation where I'm saying "If I had only bought the other one"
That's why there's always used items for sale I guess.
