Here is how I see the used Swaro binocular market.
Used current model SLCs - $1250 little more if you have the box and everything, little less if you just have the binoculars.
Used previous model (2010-2011 "first gen HD") $1150 ittle more if you have the box and everything little less if you just have the binoculars. Same as the current model except these also have an additional close focus mechanism which has been removed in the current version.
SLC NEU - this has swarobright plus additional coatings. People seem to ask $900ish
SLC "swarobright only" (15-20 years old) People seem to ask $800 but dont get bids on ebay
If you have "rarer" sized SLC like 10x50 or 8x50 people seem to ask a lot on ebay and get no bids. I think there are some 10x50 on ebay now for $2200....
Current EL Swarovision Field Pro model $2200+/- once again with the box.
EL SV non field pro $1800 +/-
EL non SV $1250+/- There are some at a pawn shop online right now for $1050 and havent sold for the last week I have seen them on there.
If you buy used always call Swaro to verify you aren't buying something stolen. If you ever send in your used Swaros they will check.
