Bull...oney. I'm using the older Furnuni 600L for four or five years now and love it. I can see it fine in daylight even with my Costa's on. The new 620 has even better VIZ, so that's the only one on your list I'd consider.

That said, I also had a 582 on the Albe. The 600 will be good out to about 800' as previously stated, and is certainly all you need out to 500. Past 500' the 585 would be the way to go. I'd love to have the new 620 just for the gain knob. Wanna buy a 600L?
