I have a pair of Swarovski 8x30 SLC that are at least 25 years old. I noticed that they were not as clear as they used to be, so I sent them to Swarovski for rapair. I just got them back today, and they are better than ever! For about $300. they replaced and updated everything except the original tubes, over 40 parts including new armor coating. They did an excellent job and for about $300 I basicaly got a new set of $1,200 binoculars.
