I'm looking for a new bino for hunting. I don't abuse em but I'm very hard on em and use em hard nearly 4 months out of the year including travel. Alaska, Yukon, elk & deer hunting in lower 48...you name it I put them thru their paces. I burned up a set of 10x42 SLC a few years ago and my Zeiss 10x42s are now down for the 2nd time for a new twist on eye cup???? Can anyone say how the Leupolds hold up under hard use. Any others built like a tank with premium grade optics?? Thanks, 163bc
