Leica is very good about warranty IF you register the warranty card. Passport will cover anything but theft, fire, or loss (this is the territory of homeowner's ins).
Pete, if by Swaro HD, you mean the SLC HD, I agree with you that it is a great bino -- the best that Swaro makes for hunters. The EL Swarovision is also a great bino, but it has a field flattener. That is awesome for birding (and other short-term, stationary viewing opportunities), but you don't want a field flattener in a bino to use for long viewing sessions (grid glassing for game) or watching a lot of movement (sporting events).
